Removing an AC 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 needs 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. If applicable, unlatch and lift the optional cable management arm if it interferes with the power supply unit (PSU) removal. For information about the cable management arm, see the system's rack documentation. Follow the safety guidelines listed in the Safety instructions section. Steps 1. Disconnect the power cable from the power source and from the PSU you intend to remove, and then remove the cables from the strap. 2. Press the release latch and slide the PSU out of the chassis by using the PSU handle. Figure 40. Removing an AC PSU 1. release latch 3. PSU 5.
