Hot-plug power supplies
IMPORTANT: Do not install the power supplies until after the server is installed in the rack.
Leaving the power supplies out reduces the weight of the server for purposes of rack
installation.
The server supports a second hot-plug power supply to provide redundant power to
the system in the event of a failure of the primary power supply. You can install or
replace a second hot-plug power supply without powering down the server.
