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