Cache Active light is off - The cache contains no data. Go to step 8.

Cache Active light is illuminated - Write-back caching is enabled and data is in the cache. Wait for the data to clear from the cache memory and for the Fast Write Cache or Cache Active light to turn off, and then go to step 8. For information on cache memory protection and settings, refer to the Array Management Window online help.

Caution – Potential damage to drives and data loss. Turning the power off and on without waiting for the disk drives to spin down can damage the drives and may cause data loss. Always let at least 30 seconds elapse from when you turn off the power until you turn it on again.

8. Turn off both power switches on the back of the command module.
