7 Upgrading to Two Redundant
Power Supply Modules
Follow the instructions in this section when you want to upgrade to two
420W redundant power supply modules.
To reduce the risk of electric shock, make sure to
disconnect all power supply cables from the wall
socket before opening the system housing.
7.1 Removing the Existing Power Supply
1. Unplug the AC power cable from the wall socket, then remove the
plastic fan cover on the rear panel.
2. Open and remove the lower front and left doors. See section 5.
3. Remove the three screws that secure the right door.
DO NOT open the RIGHT door at this moment!
Doing so will damage the power sharing board
and cables attached to its inner side.
4. Unplug the connectors
- from the power supply to the power sharing board
- from the power sharing board to the system board
- from the power sharing board to the disk drives
- from the fans to the system board
Remember where you unplugged each connector. You will have to
reconnect them later.

Installation Guide
5. When finished disconnecting all the cables attached to the inner side of
the right door, open and remove the right door.
Be careful when opening and removing the right
door to avoid damaging the power sharing board
attached to its inner side.
6. Remove the screws that secure the power supply holding plate.

7.2 Installing the Power Supply Modules
1. After you have removed all the screws that secure the existing power
supply module to the lower bay, carefully move the module to the upper
power supply bay.
2. When in place, secure the first power supply with screws.
3. Get the second redundant power supply ready.
4. Firmly hold the power supply and align it to the lower bay.
5. When in place, secure the second power supply with screws.
6. Reinstall the right door but do not close it completely.

Installation Guide
7. Connect all the power supply cables to the connectors on the power
sharing board. Make sure to connect the connectors of power supply 1
to the three upper connectors on the power sharing board. Connect the
connectors of power supply 2 to the three lower connectors on the
power sharing board.
The power connectors are foolproof and connect
only in one direction. If a connector does not fit in
completely, reverse its orientation then try to
reconnect.
8. Arrange all the cables from the power sharing board and fans to
facilitate connection to the system board and disk drives. Do not let
power cables block the housing exhaust and fans.
9. Close the right door completely and secure it with the screws that you
removed earlier.
10. Reconnect the fan connectors.
11. Reconnect the system board power connectors.
