LED | Status |
|
|
Temperature and Ventilation Status | GREEN LED indicates that blowers are operating at an acceptable RPM, and the internal |
| temperature sensors are within acceptable limits. |
| Alternating GREEN and RED LED indicates a predicted blower failure, or rapid temperature |
| increase. |
| RED LED indicates that a blower has failed, or the unit is too hot; an audible alarm will also |
| sound. |
|
|
Power Supply Status | GREEN LED indicates both power supplies are functional. |
| RED LED indicates either power supply has failed; an audible alarm sounds. In this case, the LEDs |
| on each power supply should be examined to determine which has failed. |
| IMPORTANT: |
| • Inadvertently removing the functional, surviving power supply will result in system failure and |
| possible data loss. |
| • A failed power supply or blower should be replaced as quickly as possible. Do not remove the |
| failed power supply until a replacement is on hand. Continued operation with a failed power |
| supply or blower will result in a dramatic, irreversible reduction in system life. |
|
|
Management Alarm | GREEN LED indicates normal status. |
| RED LED indicates a RAID controller board error. |
|
|
Silence Button | Insert a paper clip to silence the audible alarm, or to confirm creation of a RAID set. |
|
|
Disk Drive Alarm | AMBER LED indicates that a drive is suspected to be bad. |
|
|
Disk Drive Activity | GREEN LED indicates that an installed drive is in a ‘ready’ state. During activity, the LED will |
| flicker. |
