Appendix C - Power Subsystem C-1
Appendix C Power Subsystem
The power subsystem consists of a power backplane, swappable power supply
modules, and an optional uninterruptible power supply (UPS) module held in
place by a metal rack enclosure. The backplane and the rack allow installation of
up to three 400-watt power supply modules in a load-sharing (across two),
redundant configuration.
A redundant power configuration enables a fully-configured system to continue
running even if one power supply fails. The remaining power supply module(s)
still satisfy the system’s power requirement.
The optional UPS provides a reliable power backup in case of a total AC power
loss.

It comes with a battery and a charger to continuously recharge the battery
whenever the system power is on.

To use the UPS feature, you must have Acer Server Manager (ASM) Pro installed.
