Power and Media Module Removal and Replacement Procedures
Removing and Replacing a Hot-Plug Power Supply
To remove and replace a hot-plug power supply with the system power on:
1. Press the power supply latch to release the power supply handle (1).
2. Rotate the power supply handle outward (2) and slide the power supply out of the
chassis (3), as shown in Figure 5-3. Use both hands when removing the power supply to
support its weight. Power supplies weigh 4.09 kg (9 lbs) each.
NOTE: When you remove the power supply, a spring-loaded trap door closes to block the opening.
This door preserves the air path required to cool the internal components of the server.

3. Remove the protective covers from the connector on the new power supply. For more
information, refer to the installation documentation that came with the power supply.
Keep the protective covers for future handling.
