Faults and Troubleshooting
APPENDIX

Overview

ULTAMUS RAID 4800 and ULTAMUS RAID 4800x arrays include a processor and
associated monitoring and control logic to enable them to diagnose problems within the
array's power, cooling, RAID Controller or Disk I/O modules, and drive systems.
The sensors for power and cooling conditions are housed within the Power Supply modules.
There is independent monitoring for each array.
If a fault is indicated on the OPS Panel, refer to EBOD I/O Module LEDs on page 52.
