Enclosure component monitoring
This section covers notifications provided by the front bezel LEDs and a detailed
explanation of the “One-Touch Annunciation” monitoring system.
As part of the monitoring notifications, an audible alarm works in conjunction
with the enclosure’s LEDs, and will sound an alert for any fault that occurs with
an enclosure component or drive. To silence the alarm, simply press the Alarm
Reset button.
Status indicator LEDs
The Status Indicator LEDs located above the Alarm Reset button, comprise the
Power-On LED, Channel Status LED, Power Supply Status LED, and Fan Status
LED. The following are descriptions of each of the LEDs.
Power LED
When the Power LED is green, it indicates that the enclosure is turned on.
Channel Status LED
The Channel Status LED is green at all times.
Power Supply Status
The Power Supply Status LED indicates the condition of the power supplies.
The LED is a steady green when both power supplies are functioning normally
and will change to orange if one of the power supplies should fail or be turned
off.
A failed power supply can be identified by the orange “Fault” LED located on
the power supply.
Fan Status
The Fan Status LED indicates the condition of the cooling fans. The LED is green
when both fans are functioning normally. The LED is orange if any of the fans
fail.
