Cisco 805 Router Hardware Installation Guide
3-4
Improperly functioning
NIC on server, PC, or
workstation.
Run the NIC diagnostic supplied by the vendor
to make sure it is functioning properly. If it is
not, replace it.
If the problem continues after these checks, call
your Cisco reseller.
Connection to the serial device is
intermittent or lost. (The CD LED
on the front panel is off.)
A cable-related problem:
— Disconnected cable.
— Damaged cable.
Make sure the connectors at both ends of the
cable are secure.
Make sure the cable is not physically damaged.
If it is damaged, order another cable from Cisco
or replace it with a similar cable.
CSU/DSU configura-
tion has been lost or
changed.
Check CSU/DSU configuration. If necessary,
reconfigure CSU/DSU so that its settings match
original provisioning parameters provided by
your WAN service provider.
Problem with serial line
or WAN service.
Contact your serial line or WAN service pro-
vider to determine if there is a problem.
Serial interface has been
shut down.
Check router configuration to determine if the
serial interface has been shut down. If this
applies, enter the no shutdown command in
serial interface configuration mode to bring the
serial interface up. For information on the soft-
ware command modes, refer to Chapter 2,
“Cisco IOS Basic Skills” in the Cisco 805
Router Software Configuration Guide.
