B-4 Ultra Enterprise 6000/5000/4000 Systems Manual—November 1996
B
The front of the cabinet contains the CD-ROM/tape tray, the keyswitch, the
even-numbered board slots, and the even-numbered power/cooling module
(PCM) slots.
The rear of the cabinet contains the AC power switch, the peripheral power
supply, the clock board, the odd-numbered board slots, and the odd-numbered
PCM slots.
For slot numbers in the 16-slot card cage, see Figure 3-6.
Air circulation is provided by the power/cooling modules. The PCMs (PCM 0
through PCM 7) have two fans each. The fans provide cooling for the PCM,
plus two adjacent board slots.
All empty board slots must be blocked by load boards for proper airflow,
cooling, and EMI protection. Other types of empty slots must be blocked by
filler panels.
B.2.2 Enterprise 5000 Server
The Enterprise 5000 server is similar to the Enterprise 6000 system but features
a shorter, 8-slot, card cage. See Figure B-2 on page B-3.
For slot numbers in the 8-slot card cage, see Figure B-3.
Functionally, the 16-slot and 8-slot cabinet servers are the same, with the only
difference being the board capacity and amount of internal space available
below the card cage. All boards are interchangeable between the two versions.
All empty slots must be blocked by filler panels for proper airflow, cooling,
and EMI protection.
Note – The load board that is required for the 16-slot Enterprise 6000 server is
not required for the Enterprise 5000.
