Basics	PowerPC 604e Microprocessor - 12

PowerPC 604e Microprocessor

The Power Macintosh 8600 and 9600 Series and Workgroup Server 9650 computers feature the PowerPC 604e RISC microprocessor. The PowerPC 604e microprocessor is installed via a card that plugs into the logic board, allowing for maximum flexibility with future upgrades.

Features of the microprocessor include

•Full RISC processing architecture

•Parallel processing units: one load-store unit, two integer units, one complex integer unit, and one floating point unit

•Separate built-in 32K caches for data and instructions

•Advanced branching techniques for improved throughput

•Bus multiplier up to 7:1 with Mach V

Basics	Peripheral Component Interconnect (PCI) - 13

Peripheral Component Interconnect (PCI)

The Power Macintosh 8600 and 9600 Series and Workgroup Server 9650 computers offer a Peripheral Component Interconnect (PCI) expansion bus. Because the PCI bus is an industry standard, most existing PCI 2.0-compliant cards (with the addition of a Mac OS-specific software driver) will work in these computers.

PCI offers significantly higher performance than the NuBus architecture used in previous Macintosh models. Running at 33 MHz, the PCI bus is up to three times faster than NuBus, offering overall enhanced system performance, particularly in the areas of video and networking.

Basics	Dual In-Line Memory Modules (DIMMs) - 14

Dual In-Line Memory Modules (DIMMs)

The computers in this manual ship with extended data output (EDO) DRAM dual in-line memory modules (DIMMs) instead of DRAM SIMMs. Whereas SIMMs have 72 pins, DIMMs have 168 pins. The extra pins provide a 64-bit data path, compared to a 32-bit data path for SIMMs. In addition, DIMMs do not have to be installed in pairs like the SIMMs on earlier Macintosh models. (However, to take advantage of memory inter-leaving, the DIMMs should be installed in paired slots. See “Memory Configurations” in Basics for more information.)

Important: The computers in this manual use +5 V DIMMs only. Single In-Line Memory Modules (SIMMs) used in previous Macintosh models are NOT compatible with these computers.

Basics	Dual In-Line Memory Modules (DIMMs) - 15
	Important: The Power Macintosh 8600 Series computers
	also use VRAM DIMMs (112-pin 70 ns or faster) instead of
	VRAM SIMMs. The VRAM SIMMs used in earlier Power
	Macintosh models are not compatible.
	Note: While the Power Macintosh 8600 and 9600 Series
	and Workgroup Server 9650 computers ship with EDO
	DIMMs, the computers’ memory controller treats EDO
	DIMMs like fast-paged (FPM) DIMMs. You can therefore
	use either EDO or fast-paged DIMMs in these computers;
	however, EDO DIMMs will run in FPM mode.

Basics	Memory Configurations - 16

Memory Configurations

The Power Macintosh 8600 logic board has eight DRAM DIMM slots, each with a 64-bit data bus. You can increase the computers’ DRAM to a total of 512 MB using 5-volt, 64-bit-wide, 168-pin, extended data output (EDO) or fast-paged mode (FPM), 70 ns DIMMs.

The Power Macintosh 9600 and Workgroup Server 9650 logic board has 12 DRAM DIMM slots, each with a 64-bit data bus. You can increase the computers’ DRAM to a total of 768 MB using 5-volt, 64-bit-wide, 168-pin, EDO or FPM, 70 ns DIMMs.

Note: These computers do not have any main memory soldered to the logic board. At least one RAM DIMM must be present for the computers to operate.

DRAM DIMMs can be installed individually; however, if you

Basics	Memory Configurations - 17
	wish to take advantage of the computer’s interleaving
	capability, which provides maximum performance, you
	must install the DIMMs in matching pairs and in paired
	slots.
	Note: Memory interleaving allows the computer to read or
	write to its memory while other memory reads or writes
	are occurring, thus providing for faster performance.
	For a pair of DIMMs to function as a single 128-bit wide
	pair, they must be the same type and size.
	Note: DIMMs purchased from different manufacturers can
	be paired as long as they are the same size and speed;
	however, they may not interleave.
	The drawings on the following pages illustrates where the
	DRAM slots are located on the PM 8600 and PM 9600/WS
	9650 logic boards and how they are numbered.

Basics	Ethernet Support - 20

Ethernet Support

There are two Ethernet ports on the PM 8600 and PM 9600/WS 9650 logic boards: an AAUI port and a 10BASE-T port. You can use only one Ethernet port at one time, however. If you have cables plugged into both Ethernet ports, the computer uses the 10BASE-T port by default.

AV Support

The Power Macintosh 8600 comes standard with an AV module that provides support for: composite video input and output, S-video input and output, audio input (left and right), and audio output (left and right).

Basics	GeoPort - 21

GeoPort

Geoport is a hardware and software communications architecture that has been optimized for computertelephony integration. It has three main attributes:

•It lets any computer connect to any telephone (analog or digital, public or private) anywhere in the world.

•Once connected, it supports an arbitrary number of independent data streams up to a total bandwidth of 2 MB/second.

•Unlike traditional asynchronous data communications (such as AppleTalk), GeoPort also supports isochronous data streams (such as real-time voice and video) and provides the real-time Application Program Interfaces (APIs) necessary to hide the implementation details from both the recipient and the sender.

Basics	PC Compatibility Cards - 22
	By attaching an Apple GeoPort Telecom Adapter to these
	computers, you can enjoy all the features of a 33.6 modem,
	including data, fax, send and receive, and voice capabilities.
	The GeoPort Telecom Adapter serves as a line interface to
	standard (analog) telephone lines. The adapter is capable of
	sending or receiving data at up to 33.6 kbps and faxes at up
	to 14.4 kbps using the GeoPort Telecom Adapter software.

PC Compatibility Cards

Apple computer offers PC Compatibility Card upgrade kits that bring full DOS functionality to the Power Macintosh 8600 and 9600 Series computers. The cards plug into any available PCI slot on the logic board. Refer to the Upgrades chapter in this manual for installation instructions.

Basics The Cuda Chip - 23

The Cuda Chip

The Cuda is a microcontroller chip. Its function is to

• Turn system power on and off

• Manage system resets from various commands

• Maintain parameter RAM (PRAM)

• Manage the Apple Desktop Bus (ADB)

• Manage the real-time clock

Many system problems can be resolved by resetting the Cuda chip (see Symptom Charts for examples). Press the Cuda reset button on the logic board to reset the Cuda chip. (See “Logic Board Diagram” later in this chapter to locate the Cuda reset button.) If you continue to experience system problems, refer to “Resetting the Logic Board” in this Basics chapter.

Basics	Resetting the Logic Board - 24

Resetting the Logic Board

Resetting the logic board can resolve many system problems (refer to “Symptom Charts” for examples). Whenever you have a unit that fails to power up, you should follow this procedure before replacing any modules.

1Unplug the computer.

2Remove the battery from the logic board.

3Disconnect the power supply cable from the logic board and then press the Power On button. (See “Logic Board Diagram” later in this chapter to locate the Power On button.)

4Wait at least 10 minutes before replacing the battery.

Basics	Resetting the Logic Board - 25
	5 Make sure the battery is installed in the correct +/-
	direction.
	6 Reassemble the computer and test the unit.
	Note: This procedure resets the computer’s PRAM. Be sure
	to check the computer’s time/date and other system
	parameter settings afterwards.
	Note: If this procedure resolves the problem, claim an
	adjustment on an SRO. If not, replace the defective
	component and DO NOT claim the adjustment procedure.

Basics	Fast SCSI - 26

Fast SCSI

The Power Macintosh 8600, 9600, and WS 9650 offer Fast SCSI support on the internal 50-pin SCSI-2 connector, which provides for significantly enhanced data throughput. The internal SCSI bus on these computers supports transfer rates up to 10 MB/sec.

Only one internal terminator is allowed on the Fast SCSI bus. In the PM 8600 and 9600, the rear hard drive (the last device in the chain on the Fast SCSI-2 bus) is terminated. None of the other devices on this bus should be terminated.

In the WS 9650, however, the unit ships with only unterminated devices attached to the Fast SCSI bus (that is, the CD-ROM drive and the optional tape drive). Therefore, there is a 50-pin terminator attached to the end of the SCSI cable.

Basics	Ultra Wide SCSI - 27
	If you are connecting an additional unterminated device to
	the Fast SCSI-2 bus in a WS 9650, leave the termination
	block attached to the end of the SCSI ribbon cable. If the
	device you want to connect is terminated, remove the
	termination block and attach the device to the end of the SCSI
	ribbon cable.

Ultra Wide SCSI

The Workgroup Server 9650/233 and 9650/350 ship with a PCI Ultra SCSI JackHammer•SE card pre-installed. This card is a high performance, single-ended, accelerated PCI to SCSI host adapter card that dramatically increases performance of SCSI devices connected to it.

The JackHammer•SE card is a PCI device that creates a high-speed interface between the CPU and disk drive. The

Basics	Ultra Wide SCSI - 28
	JackHammer can transfer data through the Ultra SCSI-3
	portion of the card at rates up to 40 MB/s (as allowed by the
	SCSI-3 specification). The PCI portion of the card is capable
	of data transfer rate bursts up to 132 MB/s. This capability
	means the Workgroup Server 9650/233 and 9650/350
	can receive data as fast as the drives can provide it. Simply
	connecting the JackHammer•SE card to the SCSI drives
	improves their overall performance.
	To ensure the best possible disk I/O performance, the WS
	9650 ships with all internal hard drives attached to the
	JackHammer•SE card via the 68-pin Ultra Wide SCSI cable.
	The WS 9650 allows for a total of four internal Ultra
	devices. Due to electrical signal limitations with Ultra
	devices, Apple Computer does not recommend connecting
	external devices to the JackHammer•SE card.
	Some of the drives that are installed in the WS 9650 at the
