Chapter 8: Diagnostics/Maintenance
Before you Begin
Before you begin troubleshooting a potential malfunction, it is a good idea to check your basic hardware con-
nections. See below.
•
Ensure power cord is firmly installed in the back panel's power inlet and the other end is plugged into the
AC power source. Ensure circuit breaker is reset or fuse is operational.
•
Ensure the unit's power switch is in the On position.
•
Verify that all RJ-48, RJ-45, and DB-9 cables are fit snugly in each appropriate port. Faulty connections
may cause a number of network interfacing or connection issues.
If you suspect the problem to be on the network end, contact your Central Office to verify proper operation.
