Troubleshooting

Diagnostic Tests

Testing the Router Module’s WAN Port

The following test requires a loopback connector. (For the HP part number and pin-outs of the required loopback connector, refer to “Loopback Connector”, page A-10.)

1.Disconnect the hub’s power cord.

2.Disconnect the WAN cable, then connect a loopback connector to the WAN port.

3.Reconnect the hub’s power cord.

4.If the WAN Net Fail LED turns on at the end of the self-test, the WAN port is bad; replace the router module.

Checking the Configuration

If neither of the above procedures corrects a problem, and you suspect that a corrupted configuration rather than the terminal connection is a possible cause, try clearing the configuration. (Refer to “Clearing the Router” on page 3-7.)
