Peripheral Unit Power
The AC input power connects to the PDU on the back of the Peripheral Unit by an AC power
cord. An internal power cord extends AC power to the AC power converter and DC power to
the backplane. A fan power connector at the rear of the PDU provides power to the fans. See
Peripheral Cabinets for views of the power system components.
At the Peripheral Unit, the power entry point is one 250 V removable fuse. In 120 Vac systems,
this fuse must be a 10 A slow blow fuse. In 240 Vac systems, the fuse must be a 5 A slow blow
fuse.
