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.
Page 19
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.

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
Page 32
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.
Page 33
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.
Page 34
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:

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.
Page 37
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.
Page 38
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.)
Page 39
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.)
Page 40
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.
Page 42
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.”
Page 43
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).
Page 44
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.
Page 47
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.
Page 48
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.
Page 49
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.

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.

Basics Configuring the SCSI ID Cable - 62

Configuring the SCSI ID Cable

When you install a drive in a
SCSI Connector on Hard Drive
SCSI Cable Connector to Hard Drive
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.
The figure on this page shows the location of the SCSI ID cable.

Seagate 2 GB model #ST32550W drive and Seagate 4 GB model #ST15150W drive
The IBM and Seagate drives (2, 4, and 9 GB) use a Type 1 cable. This cable connects to the drive board at the back of the drive tray and to the SCSI connector on the hard drive. The Type 1 SCSI cable 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.
