Prerequisites:
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.
Follow the safety guidelines listed in Safety instructions.
Disconnect the power cable from the power source and from the PSU you intend to remove, and then 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 PowerEdge manuals.
Removing a power supply unit
Press the orange release latch and slide the PSU out of the system by using the PSU handle.
Installing a power supply unit:
Slide the PSU into the system until the PSU is fully seated and the release latch snaps into place.
If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the system’s rack documentation at PowerEdge manuals.
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. Wait until the new PSU is discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify that the PSU is functioning properly.
