About Power Supplies

The server is equipped with redundant hot-swappable power supplies. Redundant
power supplies enable you to remove and replace a power supply without shutting
the server down, provided that at least two other power supplies are online and
working.
Note – If a power supply fails and you do not have a replacement available, leave
the failed power supply installed to ensure proper airflow in the server.
