cmgPsuBriefFanFault — A G700’s PSU fan has been operating at 
less than 90% of its nominal speed for between 5 and 15 minutes. 
(This may be an early warning of overheating.)

1. Verify there are faults in the system. Use the Avaya G700 

Media Gateway Processor (MGP) Command Line Interface 
(CLI) command show faults to display any faults on the 

G700. 

2. If there is a fan/temperature fault, check to see if the fans are 

working and/or if there is sufficient space around the G700 for 
air circulation. 

3. Maintenance software monitors voltages applied to the Media 

Modules and other components of the G700, and compares 
these to the general power supply unit (PSU) status bit. If none 
of these voltages are out of tolerance, but the PSU status 
indicates failure, this generates the fan fault, which will be 
indicated in the show faults command output. Replace the 

entire G700. Fans and the PSU are not field replaceable.
