Installing a Power Supply Module
To install a power supply unit module in the chassis, perform this 
procedure:
1. Using a cross-head screwdriver, remove the three screws that secure 
the blank shipping panel, from the back panel of the chassis.
Figure 39. Removing the Blank Shipping Panel from the Back Panel
2. Orient the new power supply module as shown in Figure 40 on page 
62 and slide it into the slot until the tabs with the captive screws are 
flush with the back panel of the chassis. (If you are installing only one 
power supply module, you may install it in either slot.) Light pressure 
may be required to properly seat the module on the power connector 
inside the chassis.
Caution
Do not use excessive force when seating the module, because this 
may damage the system or the module. If the module resists 
seating, remove it from the system, realign it, and try again.

Note
When installed, the AT-PWR1200 Module extends 5.6 cm (2.2 in.) 
from the back panel of the chassis.
