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

discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify that the PSU is
functioning properly.
