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.

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 13 for information about online assistance.

7 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.

If you have problems running the initial configuration dialog:

This section describes how to reset the switch by rerunning the initial configuration dialog (system configuration dialog). These

are reasons why you might want to reset the switch:

•You installed the switch in your network and cannot connect to it because you assigned the wrong IP address.

•You want to clear all the configuration settings from the switch and assign a new IP address.

Caution Resetting the switch deletes the configuration and reboots the switch.

•Did you verify that POST ran successfully 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.

•Did you wait 30 seconds after you connected the switch

and the PC before you entered the IP address in your

browser?

If not, wait 30 seconds, re-enter 10.0.0.1 in the browser, and

press Enter.

•Did you forget your password? See the “Recovering from a Lost or Forgotten Password”

section in the Troubleshooting appendix of the software

configuration guide.
