Power supply units
The server has dual, hot-swappable, load sharing, AC power supply units (PSUs). The
PSUs are accessible from the rear of the server.
The server monitors the operational status of the power supply modules so that the
management interfaces can indicate the physical location of the failed PSU. LED
indicators provide PSU status information for the state of the PSU.
