CAUTION: Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer's instructions. See the System Information document for additional information.
NOTICE: To avoid possible data loss, back up all data on the hard drives before changing the mode of operation of the integrated SCSI controller from
SCSI to RAID.
NOTE: The RAID controller memory module must be an unbuffered memory module, rated to run at 100 MHz or faster. Do not substitute registered
memory modules such as those used for system memory.
