Figure B-4 Enterprise 4500 Standalone Server - Sun Microsystems Enterprise 6500 Reference Manual

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 6500 server is not
required for the Enterprise 5500.
B.2.3 Enterprise 4500 Standalone Server
The Enterprise 4500 server uses the 8-slot card cage that is used for the Enterprise
5500, but the card cage is in a standalone cabinet (
Also note that several areas of the card cage that are covered by filler panels in the
cabinet version are used in the standalone version. These areas include the SCSI
CD-ROM/tape tray, keyswitch, and AC switch (
The power/cooling modules (PCM 0 through PCM 3) each have two fans. The fans
provide cooling for the PCM and the two adjacent board slots. Air circulation for the
system boards is provided by the power/cooling modules. In addition, the
Enterprise 4500 has a combined AC input box and fan tray.
All empty slots must be blocked by filler panels for proper airflow, cooling, and EMI
protection.
