7 Installing and Removing a Hot-swappable
Redundant Power Supply Module
The power subsystem consists of a power backplane and hot-swappable
power supply modules. These components are held in place by a metal rack
enclosure.
The backplane and the rack allow installation of up to three 430-watt power
supply modules in a hot-swappable redundant configuration. A redundant
power configuration enables a fully-configured system to continue running
even if one power supply fails. The remaining two power supply modules
still satisfy the 860-watt system power requirement.
If both fans failed to operate, the power supply
module will shutdown. The LED indicators of the
power supply module will be turned off.
If the fans are functioning properly and the power
supply failed, the fans will keep operating.
The power subsystem provide a standby current and a remote on/off feature
to support cold reboot from a remote site.
The power supply subsystem should supply a minimum 860W (2 power
supply modules) DC power to the whole system. An additional power supply
module can also be added for fail-safe redundancy.
