Each hardware component is independently powered. Power strips in the system cabinets are used to consolidate power cords to reduce the number of branch circuits required.

The fabric hardware comes with six 8-socket power strips located at the rear of the cabinet. These power strips are arranged as three strips on each side of the cabinet and provide power to the servers and other hardware components installed in the cabinet.

To provide power redundancy, Unisys recommends two AC sources with the branch circuits divided equally between the AC sources as shown in Cabinet Layout for Base Configuration—Minimum Hardware Configuration through Fully Populated Expansion Cabinet Layout with 2-Socket EPPs.

Power Redundancy

AC source redundancy for some hardware components is achieved by feeding one power supply of the hardware component from one AC source and feeding the second power supply from the second AC source. If a single AC source fails, there is no loss of operation.

Some hardware components have a single AC power input and do not support power redundancy.
