instructions that are shipped with your product.

If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the rack
documentation of the system.
2.
Connect the power cable to the PSU and plug the cable into a power outlet.
CAUTION: When connecting the power cable, secure the cable with the strap.
NOTE: When installing, hot-swapping, or hot-adding a new PSU in a system with two PSUs, allow several seconds
for the system to recognize the PSU and determine its status. The PSU status indicator turns green to signify that
the PSU is functioning properly.
