Fault Determination
Introduction
This chapter on Troubleshooting has sections that cover the following:
•
Power-On Problems
• Management Interface Problems
•
Operational Problems
•
Diagnostic Procedures
•
Browser Interface Problems
These sections are written for a user attending a new or failed installation. Flow charts outline the initial
diagnostic procedure and direct the user to specific procedures for the recommended recovery action.
These sections also provide an indication of the level to which remote diagnosis may assist.
Be aware that, when you are performing an installation, cabling problems are common.
The section on Port Failure Alarms shows how to diagnose the majority of these alarms by using the
information that is shown on the status display.
Power-On Problems
When a Cisco VG30D Voice Gateway is powered on, it performs a series of self-tests to ensure that the
hardware is functioning correctly. Normal operation of the module resumes only if all tests are
successful.
The four STATUS LEDs and the Power LED on the front panel indicate the progress of tests.
If nothing is displayed, follow the Power Supply diagnosis procedure.
Management Interface Problems
You cannot to log in to the Gateway Management Interface if:
•
The Gateway IP Address or Subnet Mask are incorrectly set
• Another User is logged in to the Gateway Management Interface
•
The last User hasn’t logged out correctly, and the Non-use timeout has not expired
