PROVISIONS APPLICABLE TO RESTRICTED SOFTWARE AND, SUBJECT TO SECTION 1, TO PUBLIC SOFTWARE (Articles 8 - 15): 8. Export Laws. Notwithstanding any provision of any Public License to the contrary, Quantum shall have no duty to deliver or otherwise furnish source code of any Public Software if it cannot establish to its reasonable satisfaction that such delivery or furnishing will not violate applicable US laws and regulations. You hereby assure that you will not export or re-export any Licensed Software except in full compliance with all applicable laws, regulations, executive orders and the like pertaining to export and/or re-export, including without limitation USA versions of the same.

Limitation of Liability. IN NO EVENT WILL QUANTUM OR ITS LICENSORS LIABILITY UNDER THIS AGREEMENT EXCEED THE PRICE THAT YOU PAID FOR THE INSTALLATION UTILITIES AND EMBEDDED SOFTWARE. FURTHERMORE, IN NO EVENT WILL QUANTUM OR ITS LICENSORS BE LIABLE FOR ANY LOST PROFITS, LOST DATA, COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES ARISING OUT OF OR UNDER THIS AGREEMENT OR THE APPLICABLE PUBLIC LICENSE. The limitation of liability set forth in this paragraph will apply whether or not Quantum or its licensor was advised of the possibility of the loss, liability or damages and notwithstanding any failure of essential purpose of any limited remedy. Since some states do not allow exclusions or limitations of liability for consequential or incidental damages, this provision may not apply to you. 11. Waiver. No delay or failure of Quantum to exercise any right under this Agreement, nor any partial exercise thereof, shall be deemed to constitute a waiver of any rights granted hereunder or at law. 12. Unlawful Provision(s). If any provision of the Agreement is held to be unenforceable for any reason, all other provisions of this Agreement shall nevertheless be deemed valid and enforceable to the fullest extent possible. 13. Applicable Law. Except with respect to any Public Software program for which the applicable Public License contains provisions expressly stating the applicable governing law (with respect to which the law so specified shall govern all aspects of such agreement, including the provisions incorporated into such Public License hereunder), the terms of this Agreement (including, to the extent allowable under the Public License, all software governed by a Public License which does not specify a governing law) will be governed by the laws of the State of California, without reference to its choice of law rules, and the United States, including U.S. Copyright laws. 14. Entire Agreement. This Agreement and all applicable Public Licenses supersede all proposals, negotiations, conversations, discussions, all other agreements, oral or written, and all past course of dealing between you and Quantum relating to the Licensed Software or the terms of its license to you, and may only be modified by writing signed by you and Quantum. 15.

Understanding the Guardian 4400 Status and Disk Drive Lights The server has two status lights, two network lights, and two lights for each of the four disk drives. Quantum recommends that you become familiar with the operation of these lights. Status and Network Lights The status and network lights are located to the right of the power button. When you look at the server from the front, the lights appear in the following order, from left to right: Power LED, System LED, LAN 1 (Ethernet 1) LED, and LAN 2 (Ethernet 2) LED. They operate as follows: • The Power LED displays the following states: • A solid green light indicates that the server is powered on. • A blinking green light indicates that the server is powered down, but connected to power. • An off light indicates that the server is powered down and not connected to power. 10 • Guardian Administrator Guide
  25. 25. Setting Up the Guardian 4400 • The System LED normally blinks green (once per second) after the server has booted up. It displays an amber light when there is a system error. • The LAN 1 LED is green when the system is active and connected to the network on the LAN 1 port. A flashing green light indicates activity between the system and other devices on the network. When the light is off, the port is disconnected or the Ethernet cable is not connected/linked to an active hub or switch. • The LAN 2 LED is green when the system is active and connected to the network on the LAN 2 port. A flashing green light indicates activity between the system and other devices on the network. When the light is off, the port is disconnected or the Ethernet cable is not connected/linked to an active hub or switch. Disk Drive Lights The Guardian 4400 has two lights below each disk drive. The left light indicates power. The right light indicates activity. The lights display the following states: • When the power LED is green and the activity LED is off, the disk drive is installed properly but is not active. • When the power LED is green and the activity LED flashes amber, the disk drive is installed properly and is actively reading/writing information. • When the power LED is amber and the activity LED is off, the disk drive is installed, but not working correctly. • When you remove a disk drive, both LEDs are off. Setup and Configuration • 11
  26. 26. Setting Up the Guardian 4400 Connecting to the Network The server has dual Ethernet ports that can connect to 10BaseT, 100BaseT, or 1000BaseT networks. A dual-port configuration offers added advantages, such as load balancing and failover. You may connect one or both of the ports. If you connect only one port, it must be the primary port (identified on page 9.) Use the provided Ethernet cables to connect the server to the network. When you connect the network cables to an active port, the network lights on the bezel (LAN 1 and LAN 2) are green.

Connecting to the Network The server has dual Ethernet ports to connect to 10Base-T, 100BaseT-, or 1000Base-T networks. A dual port configuration offers added advantages, such as load balancing and failover. You may also configure the Guardian 14000 with a single Ethernet connection. If you do, be sure to use the primary port, which is located beneath the two fans. Use the provided Ethernet cables to connect the server to the network as shown in the following illustration: Note: The Ethernet port (found below the two fans) is the primary port. Use this port to connect to the network. If you use only the Ethernet port on the NIC, the server’s IP address will not appear on the LCD. 18 • Guardian Administrator Guide
  33. 33. Setting Up the Guardian 14000 For information about configuring the Ethernet ports, see “Configuring Dual-Ethernet Options” on page 43. Connecting to the Power System When you connect the Guardian server to a power source, plug the power cords into two different sources. This strategy protects the server if one power source fails. Consider the following scenarios: • For the best protection from power failures, connect each power cord to two different UPS (uninterruptible power supply) units. Each UPS should have a minimum rating of 160 watt hours. • If you have only one UPS, connect one cord to the UPS and the other to a properly grounded electrical outlet. • If no UPS units are available, connect the power cords to two properly grounded electrical outlets on different circuits. 1. Plug the power cords (female ends) into the power connectors on the server. 2. Plug the power cords (male ends) into properly grounded electrical outlets. Note: Do not plug both cords into the same multiple-outlet surge protector or one two-socket wall outlet. Setup and Configuration • 19

The following table explains the fields in the NASManager console: Name Name of the server Model Name Model name of the server IP Address The IP address How Acquired How the IP address was assigned to the server (DHCP or static) OS Version The operating system version Discovery State The time the last discovery information was retrieved from the server 22 • Guardian Administrator Guide
  37. 37. Using NASManager Using NASManager NASManager has four basic tools: Get Information, Set IP Address, Administer via the Web Browser, and Reboot. Use the three icons in the upper left side to access the Get Information, Set IP Address, and Administer via the Web Browser tools. You can also select these three tools and Reboot from the Administration Tool pull-down menu, or by right- clicking on a Guardian server name. The following list describes the NASManager Tools that you can access from the Tools menu: • Get Information is a read-only screen that displays information about the server, including the server hardware, OS version, and server status. It also provides network information, such as IP address, gateway and Ethernet address of the primary Ethernet port. • Default Server Name is QNTMnnnnnn, where nnnnnn is the server number on your server. For example, number 140020 defaults to QNTM140020. • Set IP Address displays your IP address. If you do not have a DHCP server, use this screen to set or modify a static IP address. • Administer via Web Browser opens your Web browser to the Administration Tool for this server. • Shutdown/Reboot shuts down or restarts the server. • Edit Remote Server List adds or removes remote Guardian servers that are not on the same subnet. • Options specifies how frequently the NASManager refreshes and specifies a port address. • Refresh refreshes the NASManager screen. Opening the Administration Tool 1. Highlight a server name from the list. 2. Choose Tools > Administer via Web Browser. The Administration Tool login screen opens. 3.

  38. 38. Using NASManager http://1.2.3.4 4. Click Enter. Finding the Guardian Server IP Address The primary Ethernet port IP address is available from the following locations: • The LCD panel on the front of the Guardian 14000 displays the IP address. The 4400 does not have an LCD panel, so you must use NASManager to view the IP address. • The NASManager screen displays the IP address for any Guardian servers that are online. • The Get Information screen in NASManager displays the IP address for this server. • The Set TCP/IP screen in NASManager and in the Administration Tool displays the Dynamic Host Configuration Protocol (DHCP) assigned IP address or the statically assigned server IP address. Note: If your server LCD shows the default IP address of 10.10.10.10, it means that no DHCP server was found on the network, and that the Guardian server has not been assigned a static IP address. You may not be able to see the server on your network, and thus you may be unable to access the Administration Tool. In this situation, you must use NASManager to find the server and assign it a static IP address. Discovering Guardian Servers Use NASManager to locate other Guardian servers on the network. At startup, NASManager begins to broadcast discovery request packets to the network. Guardian servers that receive discovery requests respond with information. With Discovery enabled, remote servers that you specify on the Remote Server List appear in the same list as servers discovered on the same subnet. NASManager automatically refreshes server status information at a specified interval. By default, both Discovery and Auto Refresh are enabled. Discovery is limited to the current subnet. If you cannot find a specified Guardian, use the following procedure to manually add the server: To Add a Server 1. From the Tools menu, select Edit Remote Server List. 2. Click Add. 3. In the text box, enter the name or IP address of the server you want to add to the list. 24 • Guardian Administrator Guide

  54. 54. Reviewing Network Information Network Information Field Settings The following table defines the network settings: Port Name Ethernet1 and/or Ethernet2 IP Address Obtained by DHCP or Static IP Address The unique 32-bit value that identifies the location of the server. This address consists of a network address, optional subnetwork address, and host address. It displays as four addresses ranging from 1 to 255 separated by periods. Subnet Mask A portion of a network that shares a common address component. On TCP/IP networks, subnets are all devices with IP addresses that have the same prefix. Default Gateway The network address of the gateway is the hardware or software that bridges the gap between two otherwise unroutable networks. It allows data to be transferred among computers that are on different subnets. Domain Name Server The IP address of the network server that maintains the list of all host names. Domain Name The ASCII name that identifies the domain for a group of computers within a network. WINS Server The Windows Internet Naming Service server, which locates network resources in a TCP/IP- based Windows network by automatically configuring and maintaining the name and IP address mapping tables. Ethernet Address The unique six-digit hexadecimal (0-9, A-F) number that identifies the Ethernet port. Speed Status 10Mbps, 100Mbps, or 1000Mbps Duplex Status Half-duplex indicates two-way data flow, one way at a time. Full-duplex indicates two-way data flow simultaneously. Most hubs negotiate half duplex. 40 • Guardian Administrator Guide
  55. 55. Understanding Speed and Duplex Options Understanding Speed and Duplex Options The Ethernet ports are capable of 10/100/1000 Mbps speeds, half/full duplex, and autonegotiating configurations. The speed setting establishes the rate for transmission and reception of data. The duplex setting causes the Ethernet port to transmit packets in one- way or two-ways at the same time. Half-duplex Ethernet allows one-way transfer of data at a specified speed. Full-duplex Ethernet doubles the carrying capacity of a connection between two systems by allowing each system to simultaneously transmit and receive data. For example, a 100 Mbps/half allows 100Mbps transfer speed in one direction at a time. A 100/full allows 100Mbps transfer speed in both send and receive directions. Busy networks that involve large file transfers between multiple clients benefit most from a full-duplex Ethernet, since you can send and receive traffic simultaneously from several clients. However, you can only use full-duplex when the Guardian server is connected to an Ethernet switched port. Shared hubs do not support full-duplex. The Auto setting enables automatic negotiation of the speed and duplex based on the physical port connection to a switch. If you select Auto, the switch port must be configured to the same setting as the Guardian server. The Auto setting is the only allowable option for a Gigabit port. You cannot implement Gigabit support in a shared hub configuration. Do not try to force a Gigabit setting or you will encounter problems. Note: The networking switch or hub must match the setting you selected; otherwise, the network throughput or connectivity to the server may be seriously impacted. Configuring TCP/IP Settings Use this screen to configure or modify TCP/IP addressing for a single or dual-Ethernet installation. This screen shows the current network information for the selected Ethernet port. Consider the following scenarios: • If you did not complete the TCP/IP wizard, use this screen to configure the primary Ethernet port (Ethernet1). • If you use two Ethernet ports, use this screen to configure the Ethernet ports for standalone, failover, and load balancing. For more information on how to configure dual Ethernet ports, see “Configuring Dual-Ethernet Options” on page 43. To Configure the TCP/IP Screen The fields marked with an asterisk are required; others are optional. Networking Options • 41

If you manually configure speed/duplex settings, you must also configure the hub or switch with the same settings after you click the Save button. 4. Click Save to reboot the server. You must reboot the server to activate these settings. 42 • Guardian Administrator Guide
  57. 57. Configuring Dual-Ethernet Options Configuring Dual-Ethernet Options This section describes how to configure Ethernet1 and Ethernet2 for dual-Ethernet options. A dual-Ethernet configuration enables you to perform failover and load balancing functions. You can set up the two Ethernet ports as: • Two separate network ports. A pull-down menu that allows you to select Ethernet1 or Ethernet2 displays at the top of the TCP/IP screen. • A bonded channel that uses both Ethernet ports in a load balancing scheme. • A bonded channel in failover mode that uses the first Ethernet port as the primary network interface and the second Ethernet port as the backup. In a bonded configuration, the network uses one IP address for the server. When configuring the Ethernet ports for load balancing or failover, be sure to connect both ports to the same switch on the same subnet. Also make sure they have the same speed/duplex setting. Failover Redundant network interfaces ensure that an active port is available at all times. If the primary port (Ethernet1) fails due to a hardware or cable problem, the secondary port (Ethernet2) assumes its network identity. The transition is transparent to users, although some users may experience a few seconds of inactivity. If the failed port comes back online, it resumes its role as the primary interface. The Failover mode ensures server availability to the network, however it does not provide switch fault tolerance. Load Balancing Dual ports increase server bandwidth and help to keep users connected and files available. An Ethernet port on any server can become a bottleneck or single point of failure for a network. In a load balancing mode, the transmission load is distributed among aggregated network ports. An intelligent software adaptive agent repeatedly analyzes the traffic flow from the server and distributes the packets based on destination addresses. Load balancing can only occur on Layer 3 routed protocols (IP). Networking Options • 43
  58. 58. Configuring Dual-Ethernet Options Configuring Ethernet1 1. Select Ethernet1 from the pull-down menu. 2. Do one of the following: • Click the Obtain TCP/IP settings... radio button to assign your Guardian server an IP address from a DHCP server. • Click the Set IP address... radio button to enter the IP address information for the following fields: IP address (required) Subnet mask (required) Default gateway (optional) Domain Name Server (IP address, optional) Domain Name (ASCII text, optional) WINS server (optional) 44 • Guardian Administrator Guide
  59. 59. Synchronizing Time from a Network Service 3. Select the network speed and duplex setting combination from the pop-up menu, or enable the Auto default setting. You can configure the following speed and duplex options: Setting Speed Duplex Auto Negotiated Negotiated 10Mbps/half 10 Mbps Half 10Mbps/full 10 Mbps Full 100Mbps/half 100 Mbps Half 100Mbps/full 100 Mbps Full You must use Auto to take advantage of a full-Gigabit connection. 4. Choose one or more of the following options: • Standalone provides two separate interfaces (one IP address per port). • Failover enables Ethernet2 to automatically take over the connection if Ethernet1 fails. Only one port is active at one time. • Load Balancing enable both ports to share the transmission load while the primary port (Ethernet1) receives and transmits. 5. Click Save to update the network settings. Synchronizing Time from a Network Service Synchronization is essential to the smooth operation of network systems. A difference of milliseconds can cause problems in computer systems. Security mechanisms depend on coordinated times across the network. File system updates performed by multiple computers also depend on synchronized clock times. When you join an Active Directory Services (ADS) domain, the server synchronizes time with the ADS server.

  60. 60. Configuring Network File Protocols Configuring Network File Protocols This section shows you how to configure the Guardian server to accept Windows, NFS, AFP (Macintosh), FTP, Web, and DHCP clients. Configuring Windows Access Use the Network > Windows screen to configure access for (CIFS/SMB) Windows clients. The server provides the standard file-sharing services of a Windows server. With CIFS/SMB, you can: • Access local server files • Obtain read/write privileges to local server files • Share files with other clients The Guardian Server has been tested with the Microsoft Windows 95/98/Me, NT 4.0, 2000, and XP operating systems. To Configure Windows Access 1. Navigate to the Network > Windows screen. Note: The Guardian server provides most standard file-sharing services of a Windows 2000 server. It does not support other functions of a Windows server, such as printing. 2. To enable Windows CIFS/SMB, select Yes from the pull-down menu. Select No to disable access to this server via the CIFS/SMB protocol. 3. Enter the Workgroup/Domain Name to which the server belongs. By default, the Guardian server is configured as part of Windows Workgroup. 46 • Guardian Administrator Guide
  61. 61. Configuring Network File Protocols If you join a Windows domain through Advanced Security (Security > Windows), the domain name you entered displays here and can only be changed via the Advanced Security screen. 4. For Language Support, select the code page used by Windows clients when they transmit file and folder names in a single-byte character set: • North America/Europe refers to code page 850 (Western Europe including Afrikaans, Basque, Catalan, Dutch, English, French, German, Italian, Indonesian, Icelandic, and Spanish) • United States refers to code page 437 (US English, Indonesian, Basque, Catalan) • Nordic/Europe refers to code page 865 [Northern Europe including Danish, Finnish, Norwegian (Bokmål), Norwegian (Nyorsk), and Swedish] Note: The Guardian server supports the primary Icelandic code page (865), but does not support the secondary page (861). 5. You can enable or disable Oplock (opportunistic locking). Yes allows the Windows client to take advantage of opportunistic locking, which can help performance if the user has exclusive access to a file. No disables Oplock. 6. Click Save. Security and Authentication for Windows For information on security and authentication, see Chapter 5, "Security Management." Configuring NFS Access A share on a Guardian server is equivalent to an exported file system on an NFS server. NFS users can mount Guardian shares and access content directly, or mount a subdirectory of a share. NFS uses dynamic mounting with auto-mount or static mounting with automatic remount when the server restarts after it is shut down. The Guardian server supports NFS v2/v3. To Configure NFS Access 1. Navigate to the Network > NFS screen. The Valid Client Addresses list box displays the client machines that currently have access to the server via NFS. Networking Options • 47
