Power Supplies; Peripheral Bays - NEC NovaScale R480 E1 User Manual

Power Supplies

The server can continue its operation without interruption even if a single power supply unit fails (power redundant
configuration).
In addition, if the AC power of each power supply unit is divided into two lines, the server can continue its operation
without power interruption even if one of the AC power line fails (AC power redundant configuration).
If the power cord is disconnected from the power supply unit immediately after it is connected, the event "power
degraded" may not be registered in the OS event log, and only the event "power recovered" is registered.
Redundant Power Configuration
Your server is configured with the 100 VAC non-redundant power supply system at the factory.
To use your server with the redundant power system (100 VAC or 200 VAC), update the Platform Information Area
(PIA) and Sensor Data Record (SDR) in the server firmware.
Contact your supplier to obtain the latest firmware.
