The CPU/Memory board should be installed from the smallest even-numbered slot (0) to the largest even-numbered slot (14). The even-numbered slots are located at the front of the cabinet. When located in these slots, the component side of the board is down. If the front slots are filled, you can use slots at the rear of the cabinet, with the exception of slot 1. Slot 1 requires an I/O board because the slot connects to the SCSI tray in the front of the cabinet.

All empty slots must have a filler panel or load board installed.

Note – The 16-slot Enterprise 6000 card cage requires load boards to reduce the potential for RFI generation. The 8-slot Enterprise 5000 and 4000 card cages use filler panels, which do not have load circuits.
