Step 5
If necessary, reconfigure and restart the switch or target device.
Connecting to 1000BASE-T SFP Modules
Follow these steps to connect a Category 5 cable to a 1000BASE-T SFP module:
Caution
To prevent ESD damage, follow your normal board and component handling procedures.
Step 1
When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable
in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover
cable.
Note
When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 cable.
