Straight through cables are typically used to connect different types of devices like computers to switches or routers. They have identical wiring on both ends. Crossover cables sometimes connect the same type of devices, like two computers, and have different wiring with the orange and green sets switched on one end. Proper cable installation and avoiding noise sources helps ensure reliable Ethernet connections.

1. A. Straight Through Cable
You usuallyuse straightcable toconnectdifferenttype of devices.Thistype of cable will be
usedmostof the time andcan be usedto:
1) Connecta computerto a switch/hub'snormal port.
2) Connecta computerto a cable/DSLmodem's LAN port.
3) Connecta router'sWAN portto a cable/DSLmodem'sLAN port.
4) Connecta router'sLAN port toa switch/hub'suplinkport.(Normallyusedforexpanding
network)
5) Connect2 switches/hubswithone of the switch/hubusinganuplinkportandthe other one
usingnormal port.

cable can be usedto:
1) Connect2 computersdirectly.
2) Connecta router'sLAN port to a switch/hub'snormal port.(normallyusedforexpandingnetwork)

2. EthernetCable Tips:
 A straight-thru cablehasidenticalends.
 A crossovercablehasdifferentends.
 A straight-thru isused asa patch cord in Ethernetconnections.
 A crossoveris used to connecttwo Ethernetdevices withouta hub or for connecting two hubs.
 A crossoverhasoneend with the Orangesetof wiresswitched with the Green set.
 Looking atthe RJ-45 withthe clip facing away fromyou,Brown isalwayson the right,and pin 1 is on
the left.
 No more than 1/2" of the Ethernetcable should beuntwisted otherwiseit will be susceptibleto
crosstalk.
 Do notdeform,do notbend,do notstretch, do notstaple,do notrun parallel with powercables,and
do not run Ethernet cablesnear noiseinducing components.
