Installing an AC power supply unit
Prerequisites
NOTE:
The maximum output power (shown in watts) is listed on the PSU label.
1
Follow the safety guidelines listed in the Safety instructions section.
2
For appliances that support redundant power supply units (PSUs), ensure that both the PSUs are of the same type and have the
same maximum output power.
Steps
1
Slide the PSU into the chassis until the PSU is fully seated and the release latch snaps into place.
2
If applicable, relatch the cable management arm.
For information about the cable management arm, see the rack documentation of your appliance.
3
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, wait for 15 seconds for the appliance 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.
