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.
