Determining a defective power module
A defective power module can be determined by examining the LEDs at the power modules. If a power module
is operating well, both LEDs at the front should shine green. If this is not the case, you can first check whether
the mains connection of this power supply is connected to a wall outlet. The corresponding mains connection on
the rear of the device is labeled identically like the slot of the power supply. If this connection is all right and the
connected power net has not failed, then the power supply is defective and must be replaced.
