To install a power supply, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection

Step 2 Using two hands to support and guide the power supply, slide it partway into the power tray on the front
(PLIM) side of the chassis.

Step 4 Slide the power supply into the power shelf until the connector on the back of the module meets the

Tip
OL-10971-10
Power Supply Door Grille in Open Position
A power supply weighs about 4.5 lb (2 kg). You should use two hands when handling a
module.
The power supply door can be latched while it is still outside of the power shelf; if that occurs,
the power supply will not function according to specification. To ensure proper functionality,
the power supply door must be latched only after the power supply is fully engaged into the AC
power shelf.
