G700 Troubleshooting
1. Verify there are faults in the system. Use the G700's Media Gateway Processor (MGP) Command Line
Interface (CLI) command show faults to display any faults on the G700.
2. If a temperature alarm, turn off the G700 Media Gateway and allow it to cool.
3. If faults do appear, then resolve them by checking for fan alarms.
4.If it is a fan alarm, then check for voltage alarms. Issue the MGP CLI command show voltages to determine
voltages for the Media Modules and other components of the G700. Low voltage may be responsible for slower
fans. Voltage may be reduced by a short in one of the Media Modules or a bad power supply.
5. Systematically, remove each Media Module to determine if one of the Media Modules is responsible for
reducing the voltage levels. Replace faulty Media Module.
6.If fans are faulty then replace the entire G700. Fans are not field replaceable.

3. If fans are faulty then replace the entire G700. Fans are not field replaceable.
4. If the alarm clears in 10-20 seconds, it was a probable voltage spike. Do not replace the G700.
5. If a brown-out condition is suspected, use a power monitor to monitor the power line.
