  3. 3. Purdue University ResNet Guide1. Before You Get StartedWith a ResNet (Residence Network Services) subscription, students living inPurdue University Residences may connect their personal computers to anyauthorized campus computing resource using industry standard 10base-TEthernet interfaces. Also, students, faculty, and staff living off campus mayhave the same type of access via dial-up or Verizon ADSL service. This guideprovides information that will help subscribers using Ethernet or DSL establishand use their connections. Set-up procedures for off-campus dial-upconnections can be found in the ResNet Off-Campus Dial-up Guide availablein MATH 231.As a subscriber to ResNet, it is your responsibility to provide your own"network ready" personal computer. You will probably need to purchase anetwork adapter (also known as a network interface card or NIC) in order tomake your computer network ready. The adapter must be compatible withyour computer and have an RJ-45, 10base-T Ethernet network connector. Youwill also need to provide an industry standard category 5 (CAT 5), twisted-pairjumper cable long enough to reach the ResNet outlet on the wall of your roomor your ADSL modem. Students living on campus may purchase jumpercables from the main office of your residence.Required Equipment for IBM compatible PCsUnfortunately, many older models of PCs are not adequate for use as networkclients. Therefore, the following requirements are offered as the minimum forwhich you may expect reasonable performance from your machine as well asthe minimum configuration for which we can offer support. System Component Minimum Desirable Processor Pentium Pentium II or later RAM 32 Mb 128 Mb or more Hard Disk Capacity 4 GB 10 GB or more Operating System Windows 95 Windows 98 or laterWhen you purchase a NIC, we recommend that you keep your receipt andpackaging so that the card can be returned in the event that it proves to beincompatible with your machine. If you install your NIC prior to arriving atPurdue, please keep the driver diskette(s) with your machine. You will needthe diskette(s) if you experience problems and need to re-install the driver.Also, in order to install the driver for your NIC, you must have your WindowsCDROM with you at the time of installation. All driver installations requireRevised 7/10/01 Page 1
  4. 4. Purdue University ResNet Guideaccess to the same ".cab" files that the operating system was installed from(which are located on the Windows CDROM). There are several differentversions of the Windows CDROM and attempting to use someone elsesCDROM for this purpose may corrupt your system files.Although we do not require anyone to purchase a specific adapter, theComputing Center does not have experience with or documentation for everynetwork adapter that you could possibly purchase. Therefore, we suggest thatyou purchase one of the adapters listed below if you are not comfortable withyour own ability to troubleshoot problems that may arise with your equipment.Should you encounter a problem, the Computing Center staff will attempt tohelp you, but the functionality of your equipment is ultimately your ownresponsibility.3COM Etherlink 10/100 PCI For desktop system with PCI bus(3C905B-TX-NM)3COM Megahertz 10/100 For laptop with PCMCIA slot(3CXFE575CT)Linksys Etherfast 10/100 LAN Card For desktop system with PCI bus(LNE100TX)Linksys Etherfast 10/100 PC Card For laptop with PCMCIA slot(PCMPC100)NETGEAR Fast Ethernet PCI adapter For desktop system with PCI bus(FA310TX)SMC EZ Card 10/100 For desktop system with PCI bus(SMC1211TX)Most of these cards are for use in desktop systems that have PCI bus slotsavailable. Cards for use in ISA slots are still generally available, but they nowtend to be more expensive than the PCI versions and they are typically harderto configure.Required Equipment for Macintosh PCsUnfortunately, many older models of Macs are not adequate for use asnetwork clients. Therefore, the following requirements are offered as theminimum for which you may expect reasonable performance from yourmachine. We are only able to offer limited support for Macintosh machines.Revised 7/10/01 Page 2
  5. 5. Purdue University ResNet Guide System Minimum Desirable Component Processor 68040 Power PC or later RAM 16 Mb 32 Mb or more Hard Disk Capacity 200 Mb 1 GB or more Operating System System 7.5.3 System 7.5.3 or laterDue to the improved network features of "Open Transport", it is recommendedthat anyone using a MacOS earlier than System 7.5.3 upgrade to 7.5.3 orlater.You will have to refer to your systems documentation to determine what typeof network adapter you will need to make your machine compatible with the10base-T network connection provided by ResNet. If needed, we recommendthat you purchase a Farallon adapter such as: PN502a AAUI to UTP transceiver for many systems with onboard Ethernet PN592a-TP NIC for LC family PN590a-TP NIC for MAC II familyIf you do not know which type of adapter to purchase for your specificmachine, Farallon has an excellent Ethernet product selector on their web siteat http://www.farallon.com/products/selector/. Please make certain that theproduct you purchase is the correct type for your model of computer.2. Program ResponsibilitiesThe success of the on-campus ResNet service is dependent upon thecombined efforts of the University Residence staff, the Purdue UniversityComputing Center (PUCC), and the network subscriber. The success of theoff-campus ResNet service is dependent upon the combined efforts of VerizonNetwork Services, PUCC, and the network subscriber. By understanding theresponsibilities of each of these entities you will be in a better position to seekhelp should you encounter problems.University ResidencesRevised 7/10/01 Page 3
  6. 6. Purdue University ResNet GuideThe managers and their staffs administer the on-campus ResNet service.They process the ResNet subscription requests, submit and track all ordersfor installation and removal of service, and handle billing/refund issues. If youhave questions regarding the subscription process, contact the main office ofyour residence.Verizon Network ServicesVerizon provides the ADSL transport portion of the ResNet service for off-campus high-speed network access. Verizon handles all billing and servicerelated issues for this portion of the service. Contact information for Verizon issent to each subscriber, along with his/her IP address information, via e-mailfrom ResNet, when they sign up for off-campus ADSL service.Purdue University Computing Center (PUCC)The Computing Centers Purdue Data Network division (PDN) is responsible formaintaining the overall functionality of the network at Purdue. Upon receivingrequests from the residence hall staffs, PDN staff members perform theactivation/deactivation of the network connections to student rooms. PDN alsoprovides technical assistance to subscribers (both on and off campus) thatexperience difficulties with establishing their network connection. TheComputing Center does NOT provide repair services or general softwareconsulting for non-university owned computers.PUCC staff members never visit off-campus residences for the purpose ofservicing ResNet related issues. On campus, PDN oversees the activities ofthe Resident Computing Consultants (RCC) and dispatches a technician ornetwork engineer in the event that an RCC is unable to resolve a problem.Network SubscriberAs a subscriber to ResNet services, you are entitled to the full benefits offeredby the program. However, you are responsible for determining whether yourequipment and software are suitable for use with the ResNet services and formaintaining their functionality. It is your responsibility to obtain and install thenetwork adapter as well as necessary software needed to make your PCnetwork ready. You will need to perform all setup of your equipment andsoftware. It is also up to you to report any problems that you have with yourResNet service.You must use the IP address that was assigned to you. If you have been aResNet subscriber previously, do not attempt to use your previous IPaddress! Never try to use any other address for your machine. Use of anRevised 7/10/01 Page 4
  7. 7. Purdue University ResNet Guideaddress that was not registered for your machine may interfere with someoneelses use of the network and/or render your ResNet connectionnonfunctional. Deliberate attempts to use an address different from that,which was assigned to you, are violations of PUCC policy that will not betolerated and will be referred to the Dean of Students Office for appropriateaction.Once your ResNet connection is established, the entire World Wide Web is atyour fingertips via the Internet. Your ResNet connection does, indeed, provideyou worldwide communications for e-mail and information retrieval. Thisfreedom to roam the world from your keyboard comes with equivalentresponsibilities. It is your responsibility, as a member of the Purduecommunity, to abide by all rules and regulations associated with the use ofPurdue University facilities. These include state and federal laws as well asPurdue University regulations and policies specified in the bulletin entitledUniversity Regulations, which is available in the Dean of Students Office.You should consult the Dean of Students Office if you have any questionsabout the interpretation of a university regulation or policy. Also, read thePUCC document ZZ-POLICY for a description of PUCC policies. This documentis available in paper form in the PUCC Information Center (MATH 231) orelectronic form, via the World Wide Web, from the Computing Centers website: http://www.purdue.edu/PUCC/. Violations of these rules and regulationswill be dealt with by the proper authorities.ResNet access to the Internet is a shared resource. PUCC may limit theamount of bandwidth that any one user may consume in order to fairlyallocate resources among all ResNet users.A few DOs and DONTsHere are a few DOs and DONTs to help you understand what constitutesacceptable and unacceptable activity as a ResNet subscriber. This is not anexhaustive list, these are only a few examples. Read the policy documents,described above, for detailed information.• DO use common sense and good judgment while communicating with others on the network.• DO abide by all local, state, and federal laws as well as Purdue University regulations and policies. Violators DO get caught!• DO enjoy your connectivity without infringing on others rights to the same enjoyment. Sending threatening e-mail, excessive amounts of e-mail ("mail bombing" or "SPAM"), or other attacks designed to deprive others of their rights to use the network without interference are not permitted.Revised 7/10/01 Page 5
  8. 8. Purdue University ResNet Guide• DONT try to start an on-line business. Use of ResNet to promote any commercial or non-Purdue sanctioned activity by e-mail, web site, or any other means is not permitted. If you absolutely must become an Internet entrepreneur, find an appropriate commercial site to host your activities.• DONT distribute copyrighted material. Copyrighted material should never be distributed without the permission of the copyright owner. Posting material in any publicly accessible location is considered "intent to distribute". It is illegal to post or make available any program, image, audio or video files containing copyrighted material without the permission of the copyright owner. This includes, but is not limited to, copies of commercial software tools, games, and MP3 files.• DONT distribute pornography or other illegal materials. Posting material in any publicly accessible location is considered "intent to distribute". Any items that you choose to distribute must conform to all local, state, and federal laws as well as Purdue University regulations and policies.• DONT download or use pirated software, games, or other illegally posted materials. Be aware that these illegal downloads often contain viruses or other "trojan horse" software that may give a complete stranger control of your computer or access to all of your files.Inappropriate use of your network connection will haveconsequences!3. Installation Guidelines for IBM compatible Personal ComputersThe best sources of detailed instructions for installing your equipment are themanuals that were packaged with the equipment. It is beyond the scope ofthis guide and simply not practical for us to try and provide detailedinstructions for installation of network adapters and associated softwaredrivers. Therefore, the following should be treated as general guidelines forthe process of getting your machine operational as a client of the Purdue DataNetwork. Your machine must be fully functional prior to attempting theinstallation of a network adapter. If you are aware of any hardware orsoftware problem(s) existing in your machine, correct the problem(s) beforeproceeding with this installation!Hardware InstallationUniversity personnel, including your RCCs, are not authorized to performhardware installations in student owned computers. Therefore, if you needRevised 7/10/01 Page 6
  9. 9. Purdue University ResNet Guidehelp with hardware installation, you will need to ask your computer vendor, anauthorized service center, a family member, or friend to help you install yournetwork adapter. To install the adapter in your machine:1. Read the information supplied with the card. If there is something you do not understand, find someone that can help you figure it out (see "Getting Help" below) before attempting to install the card. Insure that any jumpers or switches that need to be set on the card are in the correct position.2. Turn off your PC and disconnect the power.3. Remove the cover from the machine.4. Select an open expansion slot that is of the same type as the adapter that you are about to install. Refer to your systems manual if you are not sure which slot is the correct type. Remove the screw that secures the filler panel for that slot and remove the panel.5. Carefully remove the adapter from its package and insert it into the empty slot. Be certain that the card is fully seated in the connector and properly aligned with the back panel. Then secure it with the screw removed from the filler panel in step 4. One of the most common problems that we have found, when subscribers ask for help, is that they have not seated the card completely. When you press hard enough to seat the adapter, you should feel it go down into the socket.6. Replace the system cover and reconnect the power.[Subscribers that reside in locations where Ethernet is not available should refer to thesection entitled “ResNet 1-Meg Modem (on-campus xDSL)” or “Verizon ADSL (off-campus)” in this document for cabling instructions.]7. Connect the jumper cable between the connector on your network adapter and the ResNet outlet, on the wall of your room, which was assigned to you. If you are the first subscriber in your room, your outlet will typically be the one labeled with "-A" appended to the room number. If your roommate is also a ResNet subscriber, both the "-A" and "-B" outlets will be active. In this case, even though either outlet will work, you should still use the outlet that was assigned to you in order to avoid future complications. Do not attempt to use the "-1" or "-2" outlets. They are only used for telephone connections and do not work as data connections. In fact, use of these outlets could damage your Ethernet interface.Revised 7/10/01 Page 7
  10. 10. Purdue University ResNet GuideSoftware InstallationTurn on your PC and let it boot. If you have a PnP capable machine runningWindows 95, the operating system should automatically detect the new cardand install the drivers for it. If you are not running Windows 95 or youradapter is not PnP capable, you may have to run an installation procedureprovided by the manufacturer. Read your manual and follow themanufacturers instructions for installing the drivers for the adapter. [If youdont have a manual or installation diskette, then it may not be possible for us to helpyou even though we will do our best.] Once the drivers have been installed, youmust tell your system what it is called (machine name) and where it can befound on the network (IP address). You also need to provide some othernecessary information that is shown here as well as provided to you by themain office of your residence (on-campus) or by e-mail (off-campus).Windows 9x[The following instructions are specifically for the Windows 95 operating system. Thisprocedure also applies to Windows 98 and Windows Me operating systems (minordifferences are noted below).]1. Right-click (click using the right mouse button) on the "Network Neighborhood" icon, then select "Properties" from the menu that is displayed. [In Windows Me, the “Network Neighborhood” icon has been renamed to “My Network Places”.] -OR- Click the "Start " button on your task bar and select "Control Panel" from the "Settings" menu. Then, double-click on the "Network" icon in the "Control Panel" window.2. Look at the list of installed components on the "Configuration" tab of the "Network" properties sheet. Verify that there are entries which include the name of your network adapter, such as: Realtek RTL8019 PnP LAN adapter or compatible TCP/IP [Sometimes a NIC is sold under more than one brand name. Windows 95 may recognize your card as being a different brand than that which you purchased. The above example is for a "Genius LAN" card that shows up as a Realtek.] If your machine has more than one adapter installed (which will be the case if you have a Dialup adapter or AOL adapter already installed), theRevised 7/10/01 Page 8
  11. 11. Purdue University ResNet Guide TCP/IP entry will include the name of your adapter like that shown in the graphic. If your adapter card does not show up in this list, then the drivers were not installed – go back and install the drivers first.3. Select the TCP/IP entry that includes the name of your adapter card (if any) by clicking on the entry, then click the "Properties" button. If the TCP/IP entry is missing, see "Troubleshooting" below. Only perform the following steps in the TCP/IP properties for your Ethernet card. The TCP/IP properties for all other adapters should be set to “Obtain an IP address automatically.”Revised 7/10/01 Page 9
  12. 12. Purdue University ResNet Guide4. On the "IP Address" tab of the "TCP/IP Properties" sheet, click the bullet in front of "Specify an IP address". On-campus subscribers enter the IP address for your machine (128.211.___.___ from the information that your main office supplied you) and the subnet mask (255.255.255.0). Off-campus subscribers use the IP address supplied to them via e-mail and 255.255.255.240 for their Subnet mask.5.

Installation Guidelines for Macintosh Personal ComputersThe best sources of detailed instructions for installing your equipment are themanuals that were packaged with the equipment. It is beyond the scope ofthis guide and simply not practical to try and provide detailed instructions forinstallation of the network adapter and associated software drivers. Therefore,the following should be treated as general guidelines for the process of gettingyour machine operational as a client of the Purdue Data Network.Hardware InstallationMany recent Macintosh machines have onboard Ethernet. There is no need toinstall a NIC inside these machines. However, you may need to attach anadapter to make your "EtherTalk" interface compatible with the industrystandard 10base-T network connection in your room. Consult your ownersmanual to determine whether an adapter is required. If you do not have anonboard Ethernet, read the manual that is provided with the network adapterthat you purchase and follow the directions given to install it in your machine.University personnel, including your RCCs, are not authorized to performhardware installations in student owned computers. Therefore, if you needhelp with hardware installation, you will need to ask your computer vendor, anauthorized service center, a family member, or friend to help you install yournetwork adapter.Subscribers that reside in locations where Ethernet is not available shouldrefer to the section entitled “ResNet 1-Meg Modem (on-campus xDSL)” or“Verizon ADSL (off-campus)” in this document for cabling instructions.Connect the twisted-pair jumper cable between the network connector (oradapter) on your machine and the ResNet outlet, on the wall of your room,which was assigned to you. If you are the first subscriber in your room, youroutlet will typically be the one labeled with "-A" appended to the roomnumber. If your roommate is also a ResNet subscriber, then both the "-A"and "-B" outlets will be active. In this case, even though either outlet willwork, you should still use the outlet that was assigned to you in order to avoidfuture complications. Do not attempt to use the "-1" or "-2" outlets. They areRevised 7/10/01 Page 17
  20. 20. Purdue University ResNet Guideonly used for telephone connections and do not work as data connections. Infact, use of these outlets could damage your Ethernet interface.Software InstallationIf you installed a NIC in your machine, you may have to install drivers for it aswell. Follow the installation instructions provided with the adapter to do this.Machines with onboard Ethernet will already have drivers installed.You must tell your system where it can be found on the network (IP address).You also need to provide some other necessary information that is shown hereas well as provided to you by the main office of your residence. The followingdirections assume that you have MacOS System 7.5.3 or later.1. Open your main menu by clicking on the apple in the upper left corner of your screen. Keeping the mouse button depressed, drag the cursor down to "Control Panels" on the menu. This will open a sub-menu. Continue to drag the cursor down to "AppleTalk" on the sub-menu and release the button.2. On the AppleTalk window, select "Ethernet" from the drop down list beside "Connect via:" (Only one entry from the list is visible until you click on the text box.) Then close the window by clicking on the button in the upper left corner of the window.3.

Enter "cc.purdue.edu" (without the quotes) in the text box under "Search domains".9. Go back and double-check your IP address entry. It is very important that you get this entry correct! Be certain that you have not accidentally entered the gateway address in this location!10. Close the window by clicking the button in the upper left corner of the window. You are now ready to test out your network connection.Revised 7/10/01 Page 19
  22. 22. Purdue University ResNet GuideTroubleshootingIf you believe that you have correctly installed your network adapter anddrivers (if necessary), but your network connection still does not function,verify that all of the installation steps were performed correctly. Check thatthe IP addresses for your host, the gateway, and the name servers wereentered accurately. Make corrections to any entry that is in error. Once youare certain that everything is correct, try it again. If your system still refusesto function properly, see "Getting Help" below.5. ResNet 1-Meg Modem (on-campus xDSL)For residence halls and apartments where Ethernet is not available, theResNet service is provided by use of the Nortel 1-Meg Modem. This modemuses a new digital subscriber line (xDSL) technology that allows data ratesthat are many times faster than normal dial-up modems (currentlyapproximately 960 kb/s down-link and 120 kb/s up-link). Although themodems data rate is slower than that of an Ethernet connection, thedifference in speed will not normally be noticeable for most network activitiessuch as viewing web pages with a web browser, reading e-mail or logging intoa remote server using telnet. Unlike a dial-up modem, the network linkprovided by this modem is available 24 hours per day. The telephone can beused normally while you are on-line with your computer - data and voicecommunications are transmitted simultaneously on the same wire.Set-up procedures for your computer (described in this Guide) are the samefor a xDSL connection as they are for an Ethernet connection, with one minorexception.

  23. 23. Purdue University ResNet Guidenetwork interface card (NIC) plugs into the data connector on the 1-MegModem rather than the ResNet wall outlet. Set-up procedures for the 1-MegModem are described below.1. Connect your computer to the modem. Both ends of your 10Base-T data cable have RJ-45 connectors (8 contacts). One end should be plugged into the connector on your computers NIC. The other end plugs into the data connector on the modem (far right connector when looking at the back of the modem).2. Unplug your telephone from the wall jack. The telephone cable has RJ-11 connectors (6 contact positions, some only have 2 or 4 contacts inserted) at both ends. One end should still be connected to your telephone. Plug the other end into the telephone connector on the modem (second from the left when looking at the back of the modem).3. Connect the modem to your wall jack. Plug one end of the supplied telephone cable (RJ-11 at both ends) into the line connector on your modem (far left connector when looking at the back of the modem). Plug the other end into the telephone wall jack in your room.4. Connect the power adapter. Plug the cable that is attached to the power cube into the 16V AC connector on the modem (second from right when looking at the back of the modem). Plug the power cube into a power outlet in your room.5. Turn the modem power switch on. Depress the rocker switch on the side that has the icon showing a "1" inside the circle. At this point, theRevised 7/10/01 Page 21
  24. 24. Purdue University ResNet Guide Power and Loop Status indicator lights should be GREEN. If not, see "Getting Help" in this Guide. The modem is now ready for use.If, during use, your ResNet connection stops working for no apparent reason,it is possible that your 1-Meg Modem has locked up. Disconnect the powercable from the modem for approximately 30 seconds, then plug it back in toreset the electronics in the modem. If this does not fix the problem, see“Getting Help” below.Modem Indicator LightsIndicators are listed below in the same order that they appear, from left toright, on the front of the unit. Power Green: Power is on. Off: Power is turned off or disconnected. Loop Tx/Rx Green: Modem is transmitting to the network. Yellow: Modem is simultaneously transmitting to and Red: receiving from the network. Off: Modem is receiving from the network. No data transfer in progress. Loop Status Green: Modem in sync with network equipment. Yellow: Modem in process of synchronizing with network equipment. Red: Modem not getting signal from network equipment. Ethernet Tx/Rx Yellow: Modem is transmitting data to the computer. Red: Modem is receiving data from the computer. Ethernet Collision Off: No data transfer in progress. Red: Ethernet collision detected. Ethernet Link Green: Active Ethernet connection with computer. Status Off: No Ethernet connection with computer.6. Verizon ADSL modem (off-campus)Off-campus faculty, staff, and students that subscribe to Verizon’s ADSLservice with Purdue as their Internet Service Provider (ISP) install theirnetwork interface card (NIC) and configure their software as describedpreviously in this guide. But, they must connect their computer’s NIC to the10BaseT Ethernet connection on the ADSL modem, purchased from Verizon, asdescribed below. The instructions given here are only guidelines, your modemRevised 7/10/01 Page 22
  25. 25. Purdue University ResNet Guidemay be different from the one illustrated here. Please refer to the instructionspackaged with the modem if you have questions.1. Connect one end of the Ethernet crossover cable to the “DATA” connector on the modem. Connect the other end of the Ethernet crossover cable to the network card in your computer. The “DATA” connection is located on the back panel of the ADSL Modem. The Ethernet crossover cable is included in the ADSL Modem package.2. Connect the RJ-45 end of the ADSL cable to the RJ-45 jack on the wall plate. Connect the RJ-11 end of the ADSL cable to the “LINE” connector on the modem. The “LINE” connection is located on the back panel of the DSL Modem. The ADSL cable is included in the ADSL modem package. (RJ-45 and RJ-11 connectors look like those on your telephone. The RJ-45 end will be wider than the RJ-11. Also, some installations use a standard telephone wall plate. In those cases, a standard telephone cable, with RJ-11 connectors at both ends, is used as the ADSL cable.)3. Connect the modem’s power pack cable to the power connector on the rear panel of the modem and plug the power pack into an available outlet.Revised 7/10/01 Page 23

Purdue University ResNet GuideADSL Modem Indicator Lights Modem Light Description Power Indicates if modem is receiving power Modem Indicates a valid link to GTE’s equipment Data If the “Data” light is on, the modem is connected and communicating with GTE and is operating at full speed. If the “Data” light is blinking, there may be a problem your connection.When your system is hooked up correctly, all three indicator lights should beon. You can double-check your connection by launching a web browser andgoing to the Purdue University home page (http://www.purdue.edu).7. Multiple Connections[This section applies specifically to the use of mini-hubs and routers on campus. Arouter or hub can be purchased for use in off-campus locations to connect more thanone machine to the ADSL modem. The hub or router that you purchase may not be thesame as one of those described below, but the wiring configuration should be verysimilar. You will have to refer to instructions packaged with the device for detailsEach machine connected to the network must have its own unique IP address. SincePurdue issues only one IP address per eligible person for use with off-campus ADSL,one individual cannot use a hub to connect more than one machine. Instead, he/shemust use Network Address Translation (typically via a router) to connect more than onemachine.Revised 7/10/01 Page 24
  27. 27. Purdue University ResNet GuideHubs cannot be used to connect multiple machines to Ethernet ports in the residencehalls.]Since a 1-Meg Modem only has one network connector, an additional piece ofequipment is necessary to share that connection between two or morecomputers. In most locations, where there are only two residents per room orapartment, a mini hub is used to provide the additional connection. The 1-Meg Modem has a design limitation allowing only two network connections. Itis necessary to use Network Address Translation (NAT) in locations wherethere are three or more residents. Therefore, the Linksys Etherfast Cable/DSLRouter is used to provide the additional connections. Please refer to the set-up instructions (below) for the device that your residence provided you.Mini HubsThe 1-Meg Modem is capable of supporting two subscribers. If bothoccupants of a room that is serviced by xDSL subscribe to ResNet, the secondsubscriber will be issued a mini hub instead of a 1-Meg Modem. Instructionsfor connecting the mini hub are given below. Please note that both subscriberswill need to connect their PCs NIC to the mini hub – only the mini hubconnects to the 1-Meg Modem.On the back of the mini hub is a power connector (far right), four RJ-45 dataconnectors, and a slide switch. While referring to the diagram below, performthe following steps to connect your mini hub.Revised 7/10/01 Page 25
  28. 28. Purdue University ResNet Guide1. Insure that the slide switch is set to the "MDI [to HUB]" position (toward the outside of the box). Your ResNet connection will not work if this switch is in the wrong position.2. Connect the data connector labeled "4" (far left connector) to the RJ-45 data connector on the 1-Meg Modem (far right connector) using a 10Base-T jumper cable. If your roommates computer is already connected to the RJ-45 data connector on the 1-Meg Modem, then it will have to be disconnected first.3. Connect the network interface card (NIC) of each PC to the RJ-45 data connector labeled "1" or "2" on the mini hub using 10Base-T jumper cables.4. Connect the power cube cable to the power connector (far right) on the mini hub and plug the power cube into a power outlet in your room. The mini hub does not have a power switch. Therefore, the hub is "ON" as long as the power cube is plugged into power.Revised 7/10/01 Page 26
  29. 29. Purdue University ResNet GuideAssuming that all of the connections have been made correctly and that thepower is ON to all of the equipment, the Ethernet Link Status LED on the 1-Meg Modem should now be green. Also, the mini hub LEDs labeled "1", "2","4", and "POWER" should all be on. The LEDs labeled "1", "2", "3", and "4" arelink status indicators which are equivalent to the Ethernet Link Status LED onthe 1-Meg Modem. If your LEDs indicate different states than the onesdescribed here, you should go back and double-check all of your connections.The remaining two LEDs on the front of the mini hub are labeled "ACTIVITY"and "COLLISION". The activity LED will flash each time an inbound oroutbound data packet is detected by the hub. The collision LED lights whentwo PCs try to transmit at the same time and the data packets "collide" on theEthernet. This is a normal condition that occurs occasionally on Ethernetnetworks. But, if this LED stays on continuously, there is a problem - see"Getting Help" above.Revised 7/10/01 Page 27
  30. 30. Purdue University ResNet GuideThe Linksys Etherfast Cable/DSL RouterIn locations where there are three or more residents in a room or apartment,the Linksys Etherfast Cable/DSL Router is used to provide multiple connectionsto the network through the 1-Meg Modem. Due to the fact that the routeruses Network Address Translation (NAT), there is only one public IP addressassociated with the connection. Subscribers in these locations are issuedprivate IP addresses that begin with “192.168”. These addresses are onlyusable on the private network that is created within your room or apartmentby the four-port switch that is built into the Linksys Etherfast Cable/DSLRouter. Therefore, even the first subscriber in a room or apartment must usethe router along with the 1-Meg Modem in order to establish a usableconnection.In addition to providing multiple connections, the Linksys Etherfast Cable/DSLRouter also acts as a firewall between the private network in your room orapartment and the public network. This feature provides additional security,but as a result, has some limitations as well. The most notable limitation isthat you will not be able to use Microsoft File and Printer Sharing between yourcomputer and your neighbor’s computer (other than your roommates’machines on your private network). Also, since your computer does not havea public IP address, it is not possible to run a public server (FTP, HTTP, etc.)on your machine and have it accessible from the Internet. The router providesfor one exception to this rule: ONE machine can be set up to use IP address192.168.xxx.200 (where xxx is the subnet number of your private network –Revised 7/10/01 Page 28
  31. 31. Purdue University ResNet Guideusually your building number) which is called the DMZ address. The routerforwards all TCP/IP ports from the public IP address to the DMZ address.[It is not possible to disable the firewall function of the router due to the nature of NAT.]The 10/100 four-port switch built into the router is capable of port-to-portspeeds of 100 Megabits per second. So, file transfers and games playedbetween your machine and your roommates’ machines will be lightning fast ifyou are using 10/100 NICs in your machines. Data transfers to/from thepublic network will remain at speeds dictated by the 1-Meg Modem and/or theInternet route that is used.On the back of the router are a power connector (far right) and six RJ-45 dataconnectors. While referring to the diagram below, perform the following stepsto connect your router.1. Connect the data connector labeled "WAN" (far left connector) to the RJ-45 data connector on the 1-Meg Modem (far right connector) using a 10Base-T jumper cable.2. Connect the network interface card (NIC) of each PC to an RJ-45 data connector labeled "1", "2", “3”, or “4” on the router using 10Base-T jumper cables. [Do not use the “Uplink” connector.]3. Connect the power cable (with power module attached) to the power connector (far right) on the router, connect the power cord to the power module and plug the power cord into an outlet in your room. The router does not have a power switch. Therefore, it is "ON" as long as the power cable is plugged into power.Assuming that all of the connections have been made correctly and that thepower is ON to all of the equipment, the Ethernet Link Status LED on the 1-Meg Modem and the Link LED on the router should now be green. Also, onthe router, the Link/Act LEDs labeled "1", "2", “3”, or "4" that correspond tothe computers that are connected should all be on. If your LEDs indicatedifferent states than the ones described here, you should go back and double-check all of your connections.Revised 7/10/01 Page 29

Therefore, you have two options forsetting up your TCP/IP parameters on your computer. You can follow thedirections given in the “Installation Guidelines …” sections above to enter theparameters that were given to you by the main office of your residence or youcan set your machine to obtain the IP address automatically from the routervia DHCP.Revised 7/10/01 Page 30

If the LED is flickering, the router is actively sending or receiving data over that port.Full/Col If this LED is continuously illuminated (green), the connection made through the corresponding port is running in Full Duplex mode. If the LED is flickering, the corresponding connection is experiencing collisions. Infrequent collisions are normal. Too many may be an indication of a problem.100 or 10/100 The 100 LED illuminates (orange) when a successful 100 Mbps connection is made through the corresponding port. WAN Indicator lightsLink The Link LED illuminates (green) when a successful connection is made between the router and the 1-Meg Modem.Act The Act LED flickers (green) when the router is sending or receiving data via the WAN port.Diag The Diag LED illuminates (red) when the router goes through its self-diagnosis mode during boot-up. It will turn off upon successful completion of the diagnostics. If this LED stays on for an abnormally long period of time, you should seek help from the PDN staff (see “Getting Help” above).If you think that the router is hung up or not operating normally, you may trypressing the Reset button on the front of the router momentarily to clear thecondition. DO NOT hold the Reset button in for an extended period of time.This could cause the router to lose all of its settings (including its IP address)and revert to factory defaults. A PDN staff member would then have toreconfigure the router for you.Revised 7/10/01 Page 31

Using Your ResNet ConnectionRegulations and PoliciesYour use of the ResNet connection is subject to local, state, and federal lawsas well as Purdue University policies. Please refer to “ProgramResponsibilities” for details.Networking SoftwareThere are a few programs that most people find useful when taking advantageof their network connection. Two popular tools for TCP/IP networking aretelnet and ftp. Many versions of these programs can be found on Internetweb servers and FTP sites. Microsoft Windows includes basic versions of bothof these programs that can usually be found in the "WINDOWS" folder. Theother tool that most people find useful is a web browser. The two mostpopular web browsers are Netscape Navigator and Internet Explorer fromNetscape and Microsoft respectively. These programs are readily available inmost computer outlets or they can be downloaded from their web sites. Linksto these sites are included in the list of web sites below.The Internet is very much like a large city - a very large city! It providesliterally millions of big-city-like resources such as banking, communications,shopping, and education – not to mention fun and games. Unfortunately, italso has the criminal element. There are thousands of people using theInternet with one purpose: to take advantage of unprepared PC owners. Thesecurity of your computer is your responsibility. There are no firewalls orother security measures between your computer and the rest of the worldwhen you connect it to the ResNet at Purdue. All ResNet subscribers shouldhave a virus scanner running on their PC and should consider installing“firewall” software. There are free versions of both available to ResNetsubscribers. Follow the security related links on our web site for moreinformation.A few Web SitesA short list of web sites, to help you begin exploring the World Wide Web onthe Internet, can be found at http://www.purdue.edu/resnet/Links.html. Ifyou do not have a web browser installed on your PC, you will have to installone in order to follow the links in this list. Web browsers are typically severalmegabytes in size; therefore it will be helpful to use either a CD-ROM or Zipdisk to install your browser. It is also possible to download a browser from anRevised 7/10/01 Page 32
  35. 35. Purdue University ResNet GuideFTP site on the Internet. Obviously, you will not be able to access any ofthese sites from your own machine until you have your ResNet connectioninstalled and operating.9. Getting HelpIf you encounter problems while installing your network adapter or setting upyour machine for use with your ResNet service, there are several ways foryou to seek help. Often, the fastest, easiest way to get help is to ask a friendor roommate, which has already succeeded with his or her own machine, tohelp you with yours. He/she may be able to spot something that you haveoverlooked. Also, if you have Internet access, you may find answers to yourquestions on Purdues ResNet home page: http://www.purdue.edu/resnet.Subscribers that live on campus may contact your Resident ComputerConsultant (RCC). This is a student that lives in your residence and isemployed by the Computing Center to provide you help with your ResNetconnection. If you dont already know this person, you may obtain the nameof your RCC from the main office of your residence or from the ResNet homepage listed above.There are several other ways to obtain help with your ResNet connection.You may call the ResNet help line at 49-67500 or the PUCC InformationCenter at 49-49944. These numbers are not staffed 24 hours per day.Please check the Information Center’s Web page, http://labinfo.cc.purdue.edu,for current hours of operation. You may also fill in the Help Request Form onthe ResNet home page or e-mail to resnet@purdue.edu. Depending upon thenature of your problem, the appropriate personnel will be notified and they willcontact you to set up an appointment during which they will attempt to resolveyour problem.Other possible sources of help for machine configurations, though not specificto Purdue University, are the ResNet web pages for other universities. Thesemay also be a source of other interesting networking information. A list ofResNet web pages can be found athttp://rescomp.stanford.edu/directory/others.html.Revised 7/10/01 Page 33
