Functional Description B

B.1 System Overview

The 16-slot and 8-slot Enterprise 6000 and 5000 cabinet servers, and the 8-slot Enterprise 4000 standalone server, all use variations of the same general card cage design. All systems feature shared-memory multiprocessors and use the same boards, power/cooling modules (PCMs), and operating software.

B.1.1 Board Types

All systems use the same board types, with the exception of load boards and filler panels.

1.The CPU/Memory board supports up to two UltraSPARC modules and 16 SIMM slots.

2.The SBus I/O board includes two separate SBuses, each controlled by a separate ASIC. The board provides a total of three SBus slots for plug-in cards, two slots for fiber interface modules. The remaining slots are used for onboard devices.

3.The Graphics I/O board provides an SBus with two SBus slots and several onboard devices. This board also has a specialized slot for devices such as the graphics (UPA) card, a high performance frame buffer.

4.In the Enterprise 6000 system, empty board slots require load boards (part number 501-3142) to reduce the possibility of RFI generation. The Enterprise 5000 and 4000 systems use filler panels (part number 540-2592).
