9 Troubleshooting
If the P-8300 MkII display unit detects a problem, the front status LED will switch from green to orange.
To get an indication of what may be wrong, do one of the following:
•
Check the syslog server if syslog network logging is enabled
•
Check the web interface of the unit
Below are tips for solving the following potential failures or issues:
•
Microphone surveillance failure
•
LED surveillance failure
•
Foghorn detection failure
•
Display unit boot failure
1.
Start the LED test mode
NOTE: Do this when only 1 microphone has failed.
After checking the cabling, restart or acknowledge the error message in the web interface.
9.1 Microphone Surveillance Failure
If the signal coming from one or more of the microphones on the P-8301 MkII microphone unit
is malfunctioning, do the following:
1. Check the cabling
NOTE:
The power leads should be connected to the display unit, on the left side of the Mute connection. A description of all the
connectors is displayed on the back of the unit.
If the web interface indicates that all microphones are down, then the problem might lie within the power cable going to the
microphone unit.
2. Check the individual microphone cabling
NOTE:
Do this when only one microphone has failed.
After checking the cabling, restart or acknowledge the error message in the web interface.
3. Inspect the unit for physical obstruction of the failing microphone.
NOTE:
If you do not find any visible obstruction on the microphone, the unit should be consider damaged. In this case, contact Zenitel for
support.
Internal parts of the microphone unit are not serviceable.
9.2 LED Surveillance Failure
If a LED failure is indicated, do the following:
•
Start the LED test mode
NOTE:
This should indicate which LED is failing.
If any of the red indicator LEDs have stopped working, a foghorn detection might not be visible to the user; in this event contact
Zenitel for support.
Refer to the additional information under the LED test mode.
