Removing a Power Supply

Steps

To remove 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
sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.

Step 2

To unseat the power supply from the power shelf connector, unlatch the power supply’s door grille latch
and open it completely.

Note

The power supply fans may continue to turn at high speed for a few seconds after they are
unseated from the power shelf.

Caution

Take care when handling a power supply that has recently been in use; it can be hot to the
touch.

A power supply weighs about 4.6 lb (2.1 kg). You should use two hands when handling a power
supply.
