The MMU Cabinets contains the following components:
MMU user interface panel
Flywheel energy storage system
Vacuum pump
Emergency power off reset circuit breaker
Cabinet air filtersNote: The size of the UPS system determines the number of MMU Cabinets in a system. There may be as many as four MMU Cabinets per system configuration.

The system network interface contains the following components:
System network hub enclosure
Two SNH PWAs Note: Two SNH PWA boards provide primary and redundant backup. The SNH PWA boards allow up to seven Z Series UPS systems to be configured in parallel.Note: Each paralleled system cabinet contains a system network interface (SNI) PWA board. The system network allows each MMU to communicate to each other in a paralleled UPS system.
