The CPU/Memory boardshould 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 requiresload boards to reduce the
potential for RFI generation. The 8-slot Enterprise 5000 and 4000 cardcages use
filler panels, which do not have load circuits.
