Troubleshooting
During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling.
Temperature sensors
Extreme high and low temperatures can cause significant damage if they go unnoticed. When a temperature fault is
reported, it must be remedied as quickly as possible to avoid system damage. This can be done by warming or cooling
the installation location.
When a power supply sensor goes out of range, the Fault/ID LED illuminates amber and an event is logged.
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.
