Redundant Power Supply
The D400 may be provided with an optional redundant power supply unit in Power
Supply Slot 2. The second power supply provides continuous power to the D400 in the
event the primary power supply unit fails.
Additional protection can be provided if a secondary external power source is available.
In the event the primary power source fails, an automatic switchover will take place to
the redundant power source to ensure continuous power to the D400.
