Two pluggable redundant Power Entry Modules (PEMs) are located at the front bottom side of the shelf immediately below the fans. Each PEM provides power terminals for the power feed. The shelf supports redundant power supplies but the two supplies should be independently powered. Each power feed to the PEM consists of a –48 VDC cable and its corresponding return cable.
