Following are tables explaining the various behaviors of these LEDs:
|1 - Status LED||2 - Ethernet LED|
|Blinking blue||Startup; shutdown; activity|
|Blinking red and blue||RAID synchronization; software update|
|Solid purple||Updating hardware|
|Blinking purple||Communication has been lost||
|Solid blue||The respective Ethernet port is connected|

|Blinking red||Solid red for non-functional disks||RAID is degraded. Data remains intact but the array is no longer protected should another disk fail.|
|Blinking blue LED for all disks||Temperature alert (first-level warning)|
|Fans are not spinning|
|A power supply has been cut but power is provided by the second power supply and/or the UPS.|
|Solid red||Blinking blue for working disk(s)||Temperature alert (critical level). The product will shut off due to the high temperature.|
|The power supplies are not providing power and, if applicable, the UPS has run out of reserve power. The product will shut off.|
|Solid red for non-functional disk(s)||RAID has failed and all data has been lost.|
|Not illuminated on disk slots inside the chassis||A disk has not been firmly plugged into the slot's SATA connection or the disk is not receiving power.|
|Solid purple||Solid blue||Updating hardware|
|Blinking purple||Solid blue||Communication has been lost.|
|4 - Identification LED||5 - Mute LED|
