Troubleshooting

For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on

installing, removing, and connecting to XFP modules, see the XFP module documentation.

Caution Removing and installing an XFP module can shorten its useful life. Do not remove and insert SFP

modules more often than is absolutely necessary.

For instructions on using the XFP patch cable, see the “Switch Installation” chapter of the hardware

installation guide.

Verify Port Connectivity

After you connect to the switch port, the port LED turns amber while the switch establishes a link. This

takes about 30 seconds. After the switch and the target device establish a link, 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 a problem with the adapter installed in the target device. See the “Troubleshooting” section on

page 11 for information about online assistance.

before pressing the Break key or entering a break

character.

• Did you press the Break key while the

switch was still running POST?

If yes, wait until POST completes. Restart the

switch. Wait until POST completes. Confirm that the

System LED is green. Enter

flash memory.
