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.

The D400 supports the following power configurations:

•Single External AC Power Source

•Single External DC Power Source

•Two External AC Power Sources with optional redundant D400 AC-DC Power Supplies

•Two External DC Power Sources with optional redundant D400 DC-DC Power Converters
