Step 5

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

Connecting to 1000BASE-T SFP Modules

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. See

Figure 2-7.

Note You can use the mdix auto interface configuration command in the CLI to enable the auto-MDIX

feature. When the auto-MDIX feature is enabled, the switch detects the required cable type for copper

Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover

or a straight-through cable for connections to a copper 10/100/1000 or 1000BASE-T SFP module port

on the switch, regardless of the type of device on the other end of the connection.

The auto-MDIX feature is enabled by default.

Step 2 Insert the other cable end in an RJ-45 connector on a target device. See Figure 2-11.

Step 3

Observe the port status LED.

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