1.2.3Uninterruptible Power Supply (UPS)

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.
