Next steps
1. If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the
system’s rack documentation at https://www.dell.com/poweredgemanuals.
2. Connect the power cable to the PSU, and plug the cable into a power outlet.
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 and determine its status. The PSU redundancy may not occur until discovery is complete. The PSU status indicator
turns green to indicate that the PSU is functioning properly.
NOTE: For certain premium configurations with high power consumption, system PSU might stay with 2+0 mode only, 1+1
redundant mode is not available.
NOTE: While replacing the hot swappable PSU, after next server boot; the new PSU automatically updates to the same
firmware and configuration of the replaced one. For more information about the Part replacement configuration, see the
Lifecycle Controller User's Guide at https://www.dell.com/idracmanuals
