Requirement-All empty board slots must be filled with filler panels or load boards.
Requirement-For Enterprise 6500 systems, use load boards. A load board (part number 501-3142) is identified by the presence of connector sockets and passive circuitry, which reduces electrical noise at the center plane. Do not substitute filler panels, which do not have load circuits.
Requirement-For Enterprise 5500 and 4500 systems, use filler panels (part number 540-2592).
Requirement-Filler panels are required for all unused PCM bays.
