Basics Logic Board Connectors - 6 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.
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.
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.
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.
