Installing the Redundant Power Supply
Install the redundant power supply into the bottom slot. Disconnect power before
servicing.
1. Unscrew and remove the filler panel to install a redundant power supply.
2. Remove power supply from its shipping box. Handle only by the top and bottom
edges to avoid damaging the card.
NOTE:
The power I/O card in the rear of the housing delivers ac power for either one,
or if needed, two power supplies. The power I/O card is marked with a label
indicating the proper voltage.
3. At the front of the housing, use the attached handle on the power supply to
carefully slide the card into the bottom left slot towards the midplane until you feel it
connect. Be sure that you slide the card in using the card guides provided on the
housing.
4. Locate the screw in the top left corner of the power supply. Using a flat-blade
screwdriver, turn the screw counterclockwise until it stops turning. Then turn the
screw clockwise until it locks the power supply in place.

Install a replacement power supply into either the top or bottom slot. Disconnect power
before servicing.
1. Unscrew and remove the current power supply to install a replacement power
supply.

bottom edges to avoid damaging the card.
