Dell PowerEdge R330 Owner's Manual

Removing a redundant power supply unit

Prerequisites

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

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 section.
  2. Disconnect the power cable from the power source.
  3. Disconnect the power cable from the PSU and remove the straps that bundle and secure the system cables.
  4. Unlatch and lift the optional cable management arm if it interferes with PSU removal. For information about the cable management arm, see the systems rack documentation at Dell.com/poweredgemanuals.

Steps

Press the release latch and pull the PSU out of the chassis.
