UPS
The uninterruptible power supply (UPS) supplies power to a frame enclosure. There are two UPSs per frame.
The UPS is installed between the commercial power supply and the storage system and is
designed to automatically keep the system functional if a commercial power failure occurs. If the
remaining battery power in the UPS reaches a certain level, the unit initiates an orderly shutdown
of system processing, as required.
