Redundant-COT Shelf Powering

Each circuit card in the COT shelf receives power from two –48 Vdc sources. If one –48 Vdc source is lost, the
other –48 Vdc source provides power to the COT shelf circuit cards. Each –48 Vdc source is fused at maximum
rated current or according to the application specific value.
