Power Supplies - NEC Express5800/R140a-4 User Manual

Power Supplies

If your server is operated with 200 to 240 VAC power by using an optional AC cable or with 100
VAC in specific power configuration, 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 either of AC power line fails (AC power
redundant configuration).
Maximum configuration that supports redundant feature at 100 VAC

*1 No restriction is imposed except for processor and DIMM.
*2 N8100-1480F does not support this feature.
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 OS event log, and only the event "power
recovered" is registered.
IMPORTANT:
100 VAC only. Do not use the cord with 200-VAC power. To use the
server with 200 VAC, connect an optional AC cable that can accept 200
VAC.
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.
Download the latest PIA/SDR from the following WEB site.
