Using an Uninterruptible Power Supply (UPS) with the controller is highly recommended. The UPS can 
guarantee power to the system in the event of a power failure for a short time, which will allow the system 
to power down properly. 

SGI offers two types of UPS: basic and redundant. The basic UPS  is rack-mountable. It can maintain 
power to a five (5) enclosure system for seven (7) minutes while the system safely shuts down during a 
power failure. The redundant UPS contains power cells that provide a redundant UPS solution. 

NOTE : The UPS should be installed by a licensed electrician.  Contact SGI to obtain circuit and 

power requirements.
