If you suspect there is a hardware problem with a port, you can insert
the loopback connector, which is supplied with the router, into the
port to determine if the port is operating correctly. If the LED turns
solid when the loopback connector is plugged into the port, then the
port hardware is operating correctly. If the LED does not turn solid,
then review the Administration and Configuration Manual for
additional troubleshooting procedures.
NOTE: The loopback connector works only with Ethernet ports; not FC
ports. In order to test a port, you would need to change the port from FC to
Ethernet, then test the port. If you do this, the router will need to be reset for
changes to take effect. After you complete the test, you will need to
reconfigure the FC ports.
In addition to the previous troubleshooting information, there are
additional resources that can be used in the troubleshooting process.
