Installing a power supply unit
Prerequisites
1 Follow the safety guidelines listed in Safety instructions.
2 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.
Step
Slide the PSU into the system until the PSU is fully seated and the release latch snaps into place.

Next step
1 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.
