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:
