How to Replace PDB for PowerEdge R750xs

Observe safety precautions. Disconnect, remove cables, and unlatch cable management arm. Remove and replace the power supply unit (PSU). Reconnect cables, secure cable management arm, and ensure proper PSU recognition. Follow detailed guidelines for optimal PSU maintenance.

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.
Follow the safety guidelines listed in the Safety instructions.
Disconnect the power cable from the power outlet and from the Power Supply Unit (PSU) you intend to remove.
Remove the cable from the strap on the PSU handle.
Unlatch and lift the optional cable management arm if it interferes with the PSU removal.
For information about the cable management arm, see the system’s rack documentation at https://www.dell.com/poweredgemanuals.

Removing a power supply unit:
Press the orange release latch, and holding the PSU handle slide the PSU out of the PSU bay.

Installing a power supply unit:
Slide the PSU into the PSU bay until the release latch snaps into place.
NOTE: The numbers on the image do not depict the exact steps. The numbers are for representation of sequence.

If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the system’s rack documentation at https://www.dell.com/poweredgemanuals.
Connect the power cable to the PSU, and plug the cable into a power outlet.
CAUTION: When connecting the power cable to the PSU, secure the cable to the PSU with the strap.
NOTE: When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for the system to recognize the PSU and determine its status. The PSU redundancy may not occur until discovery is complete. The PSU status indicator turns green to indicate that the PSU is functioning properly.
NOTE: For certain premium configurations with high power consumption, system PSU might stay with 2+0 mode only, 1+1 redundant mode is not available.
NOTE: While replacing the hot swappable PSU, after next server boot; the new PSU automatically updates to the same firmware and configuration of the replaced one.
