Audible Alarm Mute
When the Audible Alarm sounds, it may be muted by pressing the Alarm Mute push-button, located
on the enclosure front panel. Automatic muting will take place after two minutes if the mute switch
is not manually operated.
When the alarm is muted it will continue to sound with short intermittent beeps to indicate that a
problem still exists. It will be silenced when all problems are cleared. (See also section “Thermal
Warnings“ on page 45).
LED Test Mode
The Alarm Mute push-button can also be used to activate the self-test feature for the LEDs on the
Ops Panel. The test is activated when you press the Mute push-button while no faults are present.
While the test is running all LEDs will flash.
Drive Carrier Module Faults
Disk drive status is monitored by a green LED and an amber LED mounted on the front of each Drive
Carrier Module (see Figure 33), providing the following indications:

Auto Start Failure
Unless otherwise selected at installation time, all drives in the enclosure should automatically start
their motors after power is applied. If this has not occurred there is a power problem (an alarm and
power fault indication would normally be active).
