Common Symptoms/Problems
Before you begin troubleshooting a potential malfunction, it is a good idea to check your basic hard-
ware connections. See below.
•
Ensure power cord is firmly installed in the back panel’s power jack and the other end is
plugged into the AC power source.
•
Ensure the unit’s power switch is in the On position.
•
Verify that all RJ-45, 50-pin Telco connectors, and DB-9 cables fit snugly in each back panel
jack. 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.
