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 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.
