ROUBLESHOOTING
This chapter provides information to locate, isolate, and correct functional problems with
the Switch Module and Remote Module should the need arise.
This chapter is divided into six principal areas for troubleshooting:
Baseline Checklist
– A list of simple checks used as a starting point for troubleshooting the
devices. It covers basic installation requirements, wiring info and network information.
Status LEDs
– Single and tri-color LEDs, located on the front and back panels of each unit. The
LEDs blink in specific sequences indicating the unit status during Power-Up as well as providing
status information on the System and Ethernet (LAN) connections during normal operations
Troubleshooting Procedures
– A set of
procedures providing step-by-step instructions to
identify and rectify problems.
Status Menus
– Diagnostic menus providing statistical information on all telephone ports,
Connect stats, Log and IP stats and general System information.
Remote Module Phone System Messages
– A chart listing error messages that are displayed on
the Remote Module phones.
Baseline Checklist
The Baseline Checklist is a logical list of items that are associated with an active and
operational installation. These items should be checked
BEFORE
you attempt to
troubleshoot either the Switch Module or the Remote Module.
If you find any of the items are not as stated, you must correct them and then check the
remaining items for both units to verify a complete installation.
Network Checklist
Verify that the existing network, in this case the telephone lines are capable of transmitting and
receiving calls. Disconnect the analog lines that are connected to the port labeled “Telco” on the
back of the Switch and Remote Modules and connect them to standard analog phones. From the
analog phone at the remote location call the phone at the switch location. Confirm that the analog
phone on the switch side rings, the call can be answered and that there is adequate voice quality.
Check that the IP address information (IP Address, Subnet Mask, Default Router) for the Switch
Module and Remote Module are valid and set correctly for remote configuration of the Switch
and Remote Module.
Ensure that the Web Server is enabled if attempting to configure the Switch and Remote Module
through the
Management Browser
