Redundant power supply

In its basic configuration, the server has one PSU module that adjusts
automatically to any mains voltage in the range of 100 VAC to 240 VAC.
A second PSU module can be installed optionally to serve as a redundant
power supply. If one PSU module fails, the second PSU module in the
redundant configuration ensures operation can continue uninterrupted. The
failed PSU module can be exchanged without shutting down the server.
