Installing the Power Distribution Board
Caution –
The system supplies power to the power distribution board even when
the system is powered off. To avoid personal injury or damage to the system, you
must disconnect all AC or DC power cables before servicing the power distribution
board.
1. At the front of the system, slide the power distribution board partly back into the
system until you first feel resistance.
Do not push the power distribution board all the way in.
2. Use the ejector levers at the front of the power distribution board to fully seat the
module all the way into the system.
3. Using a Phillips screwdriver, tighten the two captive screws to secure the base of
the power distribution board to the server.
4. Close the system door.
Caution –
There are several pinch points on the power supplies, so use caution
when removing or installing a power supply in the system. Refer to the caution label
on the power supplies for more information.
5. At the rear of the system, fully push all four of the power supplies back into the
system.
6. Push the lever on each power supply to the left to fully seat it in the system.
7. Connect the AC or DC power cables to all of the power supplies at the back of the
system.
8. Power on the system.
