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).
