Fault relay support

Fault relays are normally closed relays. When the FSR-112D-POE loses power, the relay contact is in a closed state, and the alarm circuit is triggered.

Starting in FortiSwitchOS 7.2.3, you can change how the ALARM LED functions for the FSR-112D-POE model, system part number P17080-04 or later. You can check the system part number with the get system status command. Use the following command to have the ALARM LED turn red when only one power supply unit (PSU) is connected:

config system global

set single-psu-fault enable

end

By default, the set single-psu-fault command is disabled.
