This section shows you some tools and techniques for identifying issues and troubleshooting Polycom
phones and expansion modules running Polycom UC software.
Use the following list as a guide to testing hardware and resolving issues, problems, or common
difficulties you may encounter while deploying this solution.
To view warnings or hardware diagnostics:
» Do one of the following:
 For Warning Messages, select Settings > Status > Diagnostics > Warnings
 For Diagnostics, select Settings > Status > Diagnostics > Test Hardware, and select one of
the following options:
 Keypad Diagnostics Tests the line keys, hard keys, and page keys on the phone and
expansion module.
 LED Diagnostics Tests the LED lights on the phone’s hard keys and expansion module’s
line keys.
 Display Diagnostics Tests the display screen on the phone and Color expansion module.
 Brightness Diagnostics Tests the brightness levels of the display screen on the phone
and Color expansion modules.
 For Line Key Information, select Settings > Status > Line Key Info and press a line key to view
information for that line key.
Flexible line key assignments do not display or display in an incorrect order on the Color
expansion module.
If the flexible line key assignments you configured for your module are not displaying or display
incorrectly on the EM, you need to detach the auxiliary cable connecting the first EM to the VVX
phone. Wait a moment, then reattach the cable to the phone. Note that if you reconnect the cable to
the phone immediately after disconnection, the software can fail to account for the number of
connected EMs.
