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.
