G700 Troubleshooting
1. 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.
2. Systematically, remove each Media Module to determine if one of the Media Modules is responsible for
reducing the voltage levels. Replace faulty Media Module.
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.
