In Case Of Difficulty - Cisco ME 3400E Getting Started Manual

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 13 for information about online assistance.

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 ran successfully before running
the initial configuration dialog?
• Did you press the Break key while the switch was still
running POST?
• Did you wait 30 seconds after you connected the switch
and the PC before you entered the IP address in your
browser?
• Did you forget your password?
Resetting the Switch
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.
Resetting the switch deletes the configuration and reboots the switch.
Caution
If not, make sure that only the System LED is green before
pressing the Break key or entering a break character.
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.
If not, wait 30 seconds, re-enter 10.0.0.1 in the browser, and
press Enter.
See the "Recovering from a Lost or Forgotten Password"
section in the Troubleshooting appendix of the software
configuration guide.
