Power Supply Redundancy
This special ordering option is equipped with two separate power supplies,
operating together and sharing the load of the whole card cage. If either of the
power supplies fails, the other one will continue to supply power to the full card
cage.
Two LED indicators show activity of each power supply. They should both light
when mains power is provided.
