Replacing the redundant power supply module

If a fault or an error has been reported for the redundant power supply, the LED of the
defective module lights up, see section "Power indicators, redundant power supply

replace the defective power supply module with a functioning new module as soon as

• The replacement of one of the two modules of the redundant power supply can be
performed, however, without shutting down the device.
