Note:

The order of the cache and ROM SIMMs will vary according to the manufacturing date of the logic board. Be sure to correctly identify the cache SIMM, which has four chips on both sides, and remove it before returning the logic board to Apple for repair. Do NOT remove the ROM SIMM before returning the logic board.

Important:

The WS 9150/120 logic board has a thermoelectric cooling device that attaches directly to the microprocessor's heatsink. You can identify this cooling device by the black and red wires that run to the right of the heatsink and plug into the logic board via a keyed connector. This device is not a serviceable item. Do not unplug this device or you may damage the logic board. Also note that the order of the cache and ROM SIMMs may vary. Be sure to correctly identify the cache SIMM and remove it before returning the logic board to Apple for repair. Do NOT remove the ROM SIMM before returning the logic board.

Basics RAID Information - 7

RAID Information

Apple RAID Software

Apple RAID (Redundant Array of Independent Disks) software protects data from loss during a disk failure and enhances the speed of data storage and retrieval. It is available for all Power Macintosh Workgroup servers.

Data protection is achieved through disk mirroring, a data storage scheme in which identical data is stored on two different disks. Apple RAID can also be configured for disk striping, a data storage scheme in which successive units of data are transferred to several disks at one time.

Basics RAID Information - 8

If you plan to install the Apple RAID software on an existing Power Macintosh Workgroup Server, or if you are reinitializing an existing Apple RAID drive, keep in the mind the following:

• If you wish to use your server’s startup disk for Apple RAID, do not install the Apple RAID program on your startup disk until you have initialized and set up new volumes on that disk. Before you initialize the startup disk, backup all valuable data.

• You must reinitialize all disks on which you will use Apple RAID volumes. Initializing with Apple RAID removes all data, so be sure to backup your disks first.

Basics RAID Information - 9

• The Apple RAID CD contains the facilities to reinstall your system software. However, if you have made any customizations to your system files, such as adding extension files, control panels, or preference files, then back up your system files now. Back them up in such a way that you can restore your system files separately from the non-system files on your disk. You will later restore your system files using the backup copy rather than the System Installer on the RAID CD, so that you preserve your system customizations.

• Apple HD SC Setup does not recognize Apple RAID volumes. If you want to remove or resize volumes on Apple RAID disks, use the Apple RAID program.

Troubleshooting

Workgroup Server 9150

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 family.

For additional assistance, contact Apple Technical Support.

Troubleshooting Cleaning Procedure for Card Connectors - 2

Cleaning Procedure for Card Connectors

A small number of cards for the Workgroup Server 9150 may contain residue on the gold edge connector pins, which may cause a variety of intermittent symptoms.

To correct the problem, inspect the connector pins with a magnifying glass. If you find residue, use a pencil eraser to gently clean the pins.

Troubleshooting Symptom Charts/Power Supply - 3

Symptom Charts

Power Supply

System does not power up

1 Reset logic board. (Refer to Additional Procedures.) 2 Reseat ROM, RAM, and cache SIMMs, and reseat terminator

card. 3 Replace power supply. 4 Replace logic board.

Troubleshooting Symptom Charts/Error Chords - 4

Error Chords

One-part error chord sounds during startup sequence

1 Disconnect SCSI data cable from hard drive and reboot

system. If startup sequence is normal, initialize hard drive.

If error chord still sounds, replace hard drive. 2 Disconnect floppy drive cable from floppy drive and reboot

system. If startup sequence is normal, replace floppy drive. 3 Reseat ROM, RAM, and cache SIMMs, and reseat terminator

card. 4 Replace logic board. Retain customer’s SIMMs.
