For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on
installing, removing, and connecting to SFP modules, see the SFP module documentation.
Caution Removing and installing an SFP module can shorten its useful life. Do not remove and
insert SFP modules more often than is absolutely necessary.
For instructions on using the SFP 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 process 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 “In Case
of Difficulty” section on page 19 for information about online assistance.
6 In Case of Difficulty
If you experience difficulty, help is available here and on Cisco.com. This section includes initial setup
troubleshooting, how to reset the switch, how to access help online, and where to find more
information.
Troubleshooting Initial Configuration Setup
If you have problems running the initial configuration dialog:
Did you verify that POST successfully ran
before running the initial configuration
dialog?
If not, make sure that only the System LED is
green 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. Power cycle the
switch. Wait until POST completes. Confirm that
the System LED is green. Enter Reload to reinstall
the flash memory.
