Chapter 2 Switch Installation (24- and 48-Port Switches)
Connecting the Switch to Compatible Devices
• 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 4, “Troubleshooting,”
for solutions to cabling problems.
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.
Note When connecting to a 1000BASE-T device, use a four twisted-pair, Category 5 or higher cable.
The auto-MDIX feature is enabled by default. For configuration information for this feature, see the
switch software configuration guide or the switch command reference.
Step 1 Insert one end of the cable into the SFP module port (see Figure 2-20). 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.

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.
