Dell MD3220, MD3200 owner manual Noncritical Conditions, 263

Page 263

•Backplane/power supply failure

•Two or more temperature sensors are unreadable

•Failure to detect or unable to communicate with peer port

NOTE: If both RAID controller modules fail simultaneously, the enclosure cannot issue critical or noncritical event alarms for any enclosure component.

When the enclosure is under critical condition, its enclosure status LED blinks amber.

Noncritical Conditions

A noncritical condition is an event or status that does not cause immediate failure, but must be corrected to ensure continued reliability of the storage array. Examples of noncritical events include the following:

•One power supply has failed

•One cooling fan has failed

•One RAID controller module in a redundant configuration has failed

•A battery has failed or is removed

•A physical disk in a redundant virtual disk has failed

When the enclosure is under noncritical condition, its enclosure status LED blinks amber.
