PowerEdge PSU: How to remove or replace a Power Supply Unit

Note: This article is part of the Server Tutorials: "Power Supply" available here .

Replacing a power supply unit is a simple action. If the server has two power supplies configured in redundant mode, which is the default setting, you can remove one of them without shutting down the server.
The remaining power supply will continue to provide the power to the server. In general, all components with an amber removal tool can be unplugged while the server is powered on.

1. Disconnect the power cable from the power source and from the power supply unit you intend to remove, and then remove the cables from the strap.
    
2. Press the release latch and slide the power supply unit out of the chassis.
