CAUTION: Ensure that both power supplies are of the same type and have the same maximum
output power.

latch snaps into place.
NOTE: If you unlatched the cable management arm in step 2 of the previous procedure, relatch
it. For information about the cable management arm, see the system’s rack documentation.
2. Connect the power cable to the power supply and plug the cable into a power outlet.
CAUTION: When connecting the power cable, secure the cable with the strap.

power supplies, allow several seconds for the system to recognize the power supply and
determine its status. The power-supply status indicator turns green to signify that the power
supply is functioning properly.
