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.

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.

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.

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.

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.
