Removing a power supply unit

Prerequisites

CAUTION:The system requires one power supply unit (PSU) for normal operation. On power-redundant systems, remove and replace only one PSU at a time in a system that is powered on.
  1. Follow the safety guidelines listed in the Safety instructions.
  2. Disconnect the power cable from the power outlet and from the Power Supply Unit (PSU) you intend to remove.
  3. Remove the cable from the strap on the PSU handle.
NOTE:The PowerEdge XR4000z only supports reverse air flow Power Supply Units (PSUs). The PSUs with blue straps are designed for reverse air flow (RAF).

Steps

Press the orange release latch, and holding the PSU handle slide the PSU out of the PSU bay.
