What to Do
1. Identify the power supply to be removed.

attached to the system rear panel.
3. Loosen the two captive screws securing the power supply to the chassis.
Figure 8–5
4. Grasp the handle and carefully pull the power supply out of the chassis.
Be careful to disconnect the power supply in a smooth motion.
Note -
reengage the supply in rapid succession. Always remove a supply completely
before reinserting the same supply or a replacement supply. Rapid seating and
unseating of power supplies will result in false error conditions.
5. If you are not replacing the power supply immediately, install a power supply
filler panel.
The filler panel is needed to maintain proper system cooling and prevent
electromagnetic interference.
a. Insert the filler panel into the bay.
