Sun Enterprise 6500/5500/4500 Systems Reference Manual

Chapter 1 Product Overview

Standard Features

The Sun(TM) Enterprise(TM) 6500/5500/4500 systems are available in three styles of enclosures. This manual has specific details for two styles used for the Sun Enterprise 6500, 5500, and 4500 servers (Figure 1-1).

Many boards and modules are used in all three enclosures, including the CPU/Memory+ board, various types of I/O+ boards, the Disk board, processor modules, memory modules, most power supplies, and the CD-ROM drive.

Enterprise 6500 and 5500 Systems

The minimum configuration for the Enterprise 6500/5500 systems is:

Data center system cabinet (system cabinet)
16-slot (6500) or 8-slot (5500) card cage
Power/cooling modules (2)
Quad fan tray
Clock+ board
CPU/Memory+ board
UltraSPARC(TM) II module
Main memory
I/O+ board
Peripheral power supply
AC power sequencer
Media tray for removable SCSI media drives, such as the SunCD(TM) drive

Figure 1-2 shows the front view of the Enterprise 5500 system. The Enterprise 6500 system is similar, but has a larger card cage (with eight boards in the front, eight boards in the rear).

Figure 1-3 shows the rear view of the Enterprise 6500 system. Again, the Enterprise 5500 system is similar.

Figure 1-3 Rear View of the Enterprise 6500 System Cabinet

The top front panel varies with the number and type of options in the upper part of the Enterprise 6500/5500 system. Figure 1-4 shows two types of panels.

Enterprise 4500 System

The minimum configuration for the Enterprise 4500 system is:

8-slot card cage
Power/cooling modules (2)
Fan box
Clock+ board
CPU/Memory+ board
UltraSPARC II module
Main memory
SBus+ I/O board
Peripheral power supply
AC power sequencer
Media tray for removable SCSI media drives, such as the SunCD drive

Definitions of Terms

Centerplane - all Sun Enterprise X500 server systems use a centerplane. The orientation of the sockets on the rear of the centerplane is opposite the orientation of sockets on the front of the centerplane.

Board orientation - Boards in the front of the card cage are installed component side down, and boards in the rear of the card cage are installed component side up. Similarly, the orientation of the power/cooling modules installed in the rear of the system chassis is opposite the orientation of power/cooling modules in the front of the system chassis.

Viewer orientation - Since boards, modules, and power/cooling modules may be located on either side of the Enterprise server chassis centerplane, the terms "front," "rear," "right," and "left" are defined in Table 1-1.

Table 1-1 Definitions of Terms


Orientation of the Server
Front	The key switch is located here.
Rear	The AC power switch and cable are located here.
Orientation of Power/Cooling Module, Board, and UltraSPARC II Module
Front	Edge nearest you as you face the unit installed in a system
Right	Side to your right as you face the front of the installed unit
Left	Side to your left as you face the front of the installed unit

Internal Options

Table 1-2 Internal Options for the Sun Enterprise Server Systems


Option	Enterprise 6500	Enterprise 5500/4500	Comments
CPU/Memory+ boards, SBus+ I/O boards, Graphics+ I/O boards, and PCI+ I/O boards	16, maximum	8, maximum	Each slot can accept any of these four types of boards: CPU/Memory+ board, SBus+ I/O board, Graphics+ I/O board, and PCI+ I/O board. Combinations can vary. One CPU/Memory+ board becomes the system master automatically. Jumper changes are not needed to select the system master. For easy cable connections, I/O+ boards should be installed at the rear of the card cage, although CPU/Memory+ boards and I/O+ boards will work in either the front or rear of the card cage.
Disk boards	2 per system (must use slot 15 if only 1 is installed)	4 per system	Can be installed only in slot 14 and slot 15 in the Enterprise 6500 system. For easier Disk boards cabling, CPU/Memory+ boards can be installed in the front and Disk boards in the rear of the Enterprise system.
UltraSPARC II modules	30	14	0-2 modules on each CPU/Memory+ board.
Memory modules	0, 8, or 16 SIMMs per CPU/Memory+ board	0, 8, or 16 SIMMs per CPU/Memory+ board	SIMM sizes are 8, 32, or 128 Mbyte DRAM. Do not mix sizes within the same bank. Add 8 SIMMs at a time. Install SIMMs in all bank 0 sockets first on each CPU/Memory+ board, from the lowest slot to the highest. Once bank 0 is full, install remaining SIMMs in bank 1 sockets in the same order.
SBus cards	15 per system	7 per system	0-3 cards per SBus+ I/O board, 0-2 cards per Graphics+ I/O board.
Graphics (UPA) cards	4 per system	4 per system	0-1 card per Graphics+ I/O board.
PCI cards	Dependent upon the type of PCI card, consult your customer representative	Dependent upon the type of PCI card, consult your customer representative	0-2 cards per PCI+ I/O board.
Media tray	CD-ROM and tape drive	CD-ROM and tape drive	Media tray takes removable-media drives only. One SunCD 32 is standard equipment per system. One optional tape drive is supported in the media tray.
StorEdge(TM) Disk Array A5000	See comments.	See comments.	The Enterprise 6500 and 5500 system cabinets support Sun StorEdge(TM) A5000 disk arrays. The expansion cabinet also supports A5000 disk arrays. Refer to documentation that comes with the disk arrays and the expansion cabinet.
