Troubleshooting: Your Array
251
• 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 has been removed
• A physical disk in a redundant virtual disk has failed
When the enclosure is under noncritical condition, its enclosure status LED 
blinks amber.
