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.

The Enterprise 5000 server is similar to the Enterprise 6000 system but features

ashorter, 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.
