60 Troubleshooting
When a power supply sensor goes out of range, the Fault/ID LED illuminates amber and an event is
logged to the event log.
Power supply module voltage sensors
Power supply voltage sensors ensure that the enclosure power supply voltage is within normal ranges.
There are three voltage sensors per power supply.
