Connecting to an SFP Module

Connecting to 1000BASE-T SFP Modules

Follow these steps to connect a Category 5 cable to a 1000BASE-T SFP module port (see Figure 2-57):

Caution To prevent ESD damage, follow your normal board and component handling procedures.

Step 1 When you connect the switch to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the RJ-45 connector. When you connect the switch to other switches or repeaters, insert a four twisted-pair, crossover cable.

Note When you connect the switch to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.

Step 2 Insert the other cable end in an RJ-45 connector on a target device.

Step 3 Observe the port status LED.

•The LED turns green when the switch and the target device have an established link.

•The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

•If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device. See Chapter 3, “Troubleshooting,” for solutions to cabling problems.

Step 4 If necessary, reconfigure and restart the switch or target device.
