Dell PowerEdge R750 Installation and Service Manual

Installing a power supply unit

Follow the safety guidelines listed in the Safety instructions.
For systems that support redundant PSU, ensure that both the PSUs are of the same type and have the same maximum output power.
NOTE:The maximum output power (shown in watts) is listed on the PSU label.
Remove the PSU blank.

Slide the PSU into the PSU bay until the release latch snaps into place.

If you have unlatched or removed the cable management accessory, re-install or relatch it. For information about the cable management when the PSU is removed or installed while the system is in the rack, see the system’s cable management accessory 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. The PSU status indicator turns green to indicate that the PSU is functioning properly.
