Figure 3-5 Power Supply Alert Shown in Trap Viewer

Performing a Loopback Test

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.
