Problems setting up
Newly installed memory fails during Self-Test or is not detected.
Possible Cause: The SO-DIMM memory module may not be properly seated or may not be
supported by ACS-8990.
Fix: Re-sit the memory module in the socket and retry. If it continues to fail try moving it to the
other memory socket. Make sure the correct memory type is being installed. ACS-8990
supports 200-pin DDR SODIMM.
Unable to access ACS-8990 after the operating system boots up.
Possible Cause: ACS-8990 is not configured.
Fix: Make sure ACS-8990 is configured for a RAID level. If no RAID level is configured the
operating system will not detect ACS-8990 as a disk drive.
I try to set up an array using Quick Setup but fail. Why?
