Basics Compatibility Issues - 16

Compatibility Issues

The following are compatibility issues associated with
upgrading memory or installing PCI expansion cards for
video, graphics applications, and networking and
communications:

• The Network Server uses 72-bit-wide, 168-pin parity

DRAM Dual Inline Memory Modules (DIMMs), which
should be installed in matched pairs (for example, two 8
MB DIMMs). Your server’s DIMMs are fast-paged mode,
parity DRAM, with an access time of 60-nanoseconds or
faster. Nonparity DIMMs with 70-nanosecond or faster
access time DRAM will work; however, if there is any
nonparity DRAM installed, all server parity checking is
disabled.

Basics Compatibility Issues - 17

• Some DIMMs and all Single Inline Memory Modules

(SIMMs) from older Macintosh computers are not
compatible. For more detailed information, see
“Appendix B: DRAM Configurations” of “Setting up the
Network Server.”

• The Network Server uses cards designed according to the

Peripheral Component Interconnect (PCI) standard.
Your server cannot accommodate NuBus cards, which
were designed for older Macintosh computers.

• The combined power consumption of PCI expansion cards

must not exceed the limits specified for the Network
Server 500 and 700 Series.

• The Network Servers support only multisynchronous

displays.

• The 8 mm tape drive can read from but not write to

standard metal particle tapes. The tape heads must be
cleaned after reading from a standard metal particle tape
before an AME tape can be used.

Basics Setup and Operation - 18

Setup and Operation

Refer to “Chapter 5: Starting Up Your Server” of “Setting
up the Network Server” and “Chapter 3: System Startup,
Logging In, Shutting Down, and Rebooting” of “Using AIX,
AppleTalk Services and Macintosh OS Utilities on the
Network Server” for information on how to

• Install AIX on the server

• Start up, log in, shut down, and restart the server

• Use AIX Windows and the Common Desktop Environment

• Use InfoExplorer

• Use system administration tools

• Set up AppleTalk and AppleTalk Services

• Use Disk Management Utility

• Access the server remotely with CommandShell

Note:

You can find these manuals on the Service Source
Companion CD.

Basics Setup and Operation - 19

Overview of Core Technologies

This section provides information on core technologies built
into the Network Server 500 and 700 Series.

PowerPC 604 and 604e Microprocessor

The Network Server 500 Series and Network Server 700
Series are powered by a PowerPC 604 or 604e
microprocessor. An implementation of the PowerPC family
of RISC microprocessors, the PowerPC 604 or 604e uses
RISC technology to deliver high performance at the lowest
possible cost. Features include the following:

• Full RISC processing architecture

• 64-bit external data bus and a 32-bit address bus

Basics Overview of Core Technologies - 30

• Five execution units that can operate in parallel (one
load-store unit, three integer units, and one three-stage
floating-point unit)

• Separate built-in caches for data and instructions, 16K
each for the 604 and 32K each for the 604e

• Advanced branching techniques for improved throughput

• Advanced 3.3-volt CMOS process technology (fully
compatible with TTL)

• Bus multiplier up to 3:1 for the 604 and up to 5:1 for
the 604e

The PowerPC 604 and 604e microprocessor is installed by
way of a processor card that plugs into the logic board,
allowing for maximum flexibility for future upgrades. The
Network Server 500 Series uses the 132-MHz version of
the PowerPC 604 microprocessor and the Network Server
700 Series uses the 150 MHz or 200 MHz version.

Basics Overview of Core Technologies - 31

Memory Configurations

The Network Server 500 Series and Network Server 700
Series provide parity memory protection by using DRAM
Dual Inline Memory Modules (DIMMs) with parity instead
of DRAM Single Inline Memory Modules (SIMMs).

The server logic board has eight DRAM DIMM slots (each
with a 64-bit wide data bus) that allow a maximum of 512
MB of main memory.

Although single DIMMs may be added, to take advantage of
memory interleaving, the DIMMs should be installed in
matched pairs (for example, two 16 MB DIMMs).

Memory interleaving allows the computer to read or write
to its memory while other memory reads or writes are
occurring, thus providing maximum performance.

Basics Overview of Core Technologies - 32

Important:

pin fast-paged mode, 60-nanosecond (ns) RAM access time
or faster. DRAM must support byte writes. SIMMs and some
DIMMs from older Macintosh computers will not work in the
Network Server. The parity DIMMS should be installed in
matched pairs (for example, two 16 MB DIMMs, one in slot
1A, the other in slot 1B). Nonparity DRAM with 70­nanosecond DRAM access time or faster will work, however
if there is any nonparity DRAM installed, all server parity
checking is disabled.

Important:

are NOT compatible with the Network Server 500 and 700
Series.

Ethernet Support

The Network Server 500 Series and Network Server 700
Series come with a built-in Ethernet port (AAUI) for
connecting to a high-speed Ethernet network. The AAUI
connector supports the Apple Ethernet Network Cable
System (which supports thicknet, thinnet, or 10BaseT
cable systems). To connect the server to an Ethernet
network, you must have one of the following Ethernet Media
adapters (depending on the type of network cabling used):

• Apple Ethernet Thin Coax Transceiver

• Apple Ethernet Twisted-Pair Transceiver

• Apple Ethernet AUI Adapter

With the appropriate communications card and software, the
server also can be connected to other network types.

Basics Overview of Core Technologies - 35

Peripheral Component Interconnect (PCI)

PCI (Peripheral Component Interconnect) is a high­performance architectural standard designed to eliminate
bottlenecks between a computer’s processor and its high
bandwidth peripherals (such as video graphics and network
components). The PCI Local Bus is a high-performance, 32­bit or 64-bit bus with multiplexed address and data lines. It
is intended for use as an interconnect mechanism between
highly integrated peripheral controller components,
peripheral add-in boards, and the processor/memory
systems.

The Network Server 500 Series and Network Server 700
Series provide six 64-bit, universal (5 volt + 3.3 volt)
PCI expansion slots that are compliant with PCI 2.0
specifications.

Basics Overview of Core Technologies - 36

The expansion slots can be used to install cards for video and
graphics applications and for networking and
communications purposes.

The Cuda Chip

The Cuda is a microcontroller chip. Its function is to

• Turn on and off system power

• Manage system resets from various commands

• Maintain PRAM

• Manage the ADB

• Manage the real-time clock

Many system problems can be resolved by resetting the Cuda
chip (see the Troubleshooting chapter for examples). Press
the Cuda reset button on the logic board to reset the Cuda
chip. (See the Logic Board Diagram earlier in this chapter to
locate the Cuda reset button.)

Basics Overview of Core Technologies - 37

If you continue to experience system problems after
resetting the Cuda chip, refer to the following section
“Resetting the Logic Board.”

Resetting the Logic Board

Resetting the logic board can resolve many system problems
(refer to the Troubleshooting chapter in this manual for
examples).

Whenever you have a unit that fails to power up, you should
follow this procedure before replacing any modules:

1 Unplug the computer.

2 Slide the rear drawer out. (Refer to the Take Apart

chapter for more instructions.)

Basics Overview of Core Technologies - 38

3 Using a small, flat-blade screwdriver, pry open the

latch at the end of the battery holder, and lift off the
battery holder cover.

4 Remove the battery from its holder.

5 Make sure that the unit is not connected to any external

devices such as SCSI or serial port devices.

6 Wait at least 10 minutes before replacing the battery.

Be sure the battery is installed in the correct positive/
negative (+/-) direction.

7 Reassemble the computer and test the unit.

Note:

This procedure resets the computer’s parameter RAM
(PRAM). Be sure to check the computer’s time/date and
other system parameter settings afterwards.

Basics Overview of New Technologies - 39

Overview of New Technologies

This section discusses new technologies being introduced
with the Network Server 500 and 700 Series.

AIX

The Network Server 500 Series and Network Server 700
Series are designed to run IBM AIX. The Network Servers
are shipped with the following software:

• AIX version 4.1.4 or 4.1.4.1 operating system

• AppleTalk and AppleTalk administration utilities.

AppleTalk allows remotely connected Macintosh
computers to access the AIX server without using TCP/IP
or other networking protocols.

Basics Overview of New Technologies - 40

• Two symbiotic applications, Discus and CommandShell,

created by Apple Computer, Inc., and engineered for use
with AIX on the Network Server 500 and 700 Series.
CommandShell is a terminal emulator that runs multiple
windows on a system, while Discus is a disk­management system that allows users to manage all
aspects of disk storage. Discus provides a graphical user
interface and offers various views of disk-storage
structure, as well as management commands.

Note:

Applications that use a Macintosh interface for
handling UNIX tasks are called “symbiotic applications.”

Basics Overview of New Technologies - 41

SCSI IDs and Drive Termination

The Network Server 500 Series and Network Server 700
Series each include three separate SCSI buses: two internal
SCSI buses and one external bus. The buses accommodate
four, five, and seven SCSI devices, respectively. Thus, a
total of 16 SCSI devices can be connected to the server
without adding PCI cards. The internal buses handle the
built-in startup hard drive, CD-ROM drive, tape drive, and
up to four additional SCSI drives on the Network Server 500
Series and six on the Network Server 700 Series. The
external bus accommodates up to seven external SCSI devices
in a chain (such as hard drives, CD-ROM drives, scanners,
printers, and tape-backup drives).

Basics Overview of New Technologies - 42

To make installing SCSI devices as straightforward as
possible, and to reduce the potential for SCSI bus problems,
the internal SCSI cable has built-in termination. Before
installing a SCSI device, make sure that SCSI termination is
disabled on the device. To disable the SCSI termination, refer
to the installation manual of that device.

Note: The Fast/Wide SCSI-2 channels support only internal

drives used in the Network Server 500 and 700 Series.

Note: The server automatically assigns SCSI ID numbers to

internal drives as shown in the diagram on the next page.

Fast/Wide SCSI

Designed to be I/O intensive, the Network Server 500
Series and Network Server 700 Series achieve enhanced
data throughput by providing two Fast/Wide SCSI-2
channels that support internal devices. The internal SCSI
buses on the Network Servers support transfer rates up to
40 MB/sec.

Note: The Fast/Wide SCSI-2 channels support only internal

drives used in the Network Server 500 and 700 Series.

Basics Overview of New Technologies - 45

Network Server PCI RAID Card

The Network Server 500 Series and Network Server 700
Series offer six PCI expansion slots each, but due to a
limitation in the PCI Redundant Array of Independent Disks
(RAID) implementation, only four Network Server PCI
RAID cards can be installed in a single Network Server 500
or 700 Series computer.

The first or a single PCI RAID card is designed to be
connected to the server’s two internal SCSI-2 buses. In that
case, the two SCSI-2 controller chips on the logic board are
disabled and all internal SCSI devices (for example, hard
drives, CD-ROM, DAT tapes, and so on) are controlled by the
controller on the PCI RAID card.

Any other RAID card(s) in the system will provide external
Fast/Wide SCSI-2 connectors for connection of external
SCSI disk arrays.

Basics Overview of New Technologies - 46

Hot-Swappable Drives

The Network Server 500 and Network Server 700 contain a
flexible SCSI backplane that allows the physical hot­swapping and hot-removal of SCSI wide and narrow devices.
This ability to gracefully handle the logical addition and
removal of drives is operating-system dependent. The
optional Network Server PCI RAID Card allows the AIX
operating system to be buffered from the logical
consequences of drive addition and removal when setup in a
RAID configuration. Hence, hot plug and removal is only
recommended for RAID configurations.

An optional PCI RAID card must be installed to ensure

Note:

that data will not be lost when drives are hot-swapped.

Basics Overview of New Technologies - 47

Hot-Swappable, Redundant Power Supplies

The Network Server 700 Series has two bays for two power
supplies. Although the server is shipped with only one
power supply installed in the left bay, when a second power
supply is installed in the other bay (right), the server
power supplies become hot-swappable. When one of the
installed power supplies fails, its LED will turn off. The
failed power supply can then be replaced without shutting
down the server. (A message will display on the LCD
indicating that it is safe to shutdown the server.)

Hot-swappable, redundant power supplies are not

Note:

available for the Network Server 500 Series.

Basics Overview of New Technologies - 48

Display and Diagnostics

On startup, the server executes the power-on self test, and
then displays the ROM version and copyright information on
the LCD. It then starts a series of tests, during which the
ROM version and the parity DRAM size remain on the
display.

During the test phase of the startup process, the server
displays startup progress messages on the LCD display.
Table 1 lists the progress messages along with the system
module(s) in use.

drive carrier, the way you
connect the SCSI ID cable to
the drive depends on which
type of drive you’re
installing. This section
describes how to connect the
SCSI ID cable for the 2
gigabyte (GB) and 4 GB IBM
and Seagate hard drives,
which are provided by
Apple for the Network
Server 500 and 700
Series. If you install a
Quantum drive or other
drive with an active high
LED signal, you need to
rewire the SCSI cable as
described later in this
section.

includes a six-pin connector
and a four-pin connector.
Check which kind of drive
you have, then connect the
cable to the drive according
to the figure on this page.

Troubleshooting General - 1

General

The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)

If you are not sure what the problem is, or if the Symptom Charts
do not resolve the problem, refer to the Flowchart for the product
