External LED Connectors
The IIR Controller has a 6 pin header to allow for connection of additional LEDs. An LED
connected with header A lights up whenever there is activity on SCSI channel A. The same applies
for header B. An LED connected with the SUM header lights up whenever there is activity on any
of the two SCSI channels A and B. See Figure 8 for details.
Terminator Power
Determines whether termination power (per channel) is supplied by the controller. The Default is
ON for both channels (both jumpers set).
Acoustical Alarm
An acoustical (audible) alarm is present on the RAID controller to indicate any of the following
events:
State of controller upon boot-up
Change in state of array
Change controller environmental status (during normal operation)
Hardware failure
If the cause of the event is resolved and/or removed, the audible alarm will cease. The audible
alarm can also be turned off manually through StorCon or StorCon plus. If the audible alarm is
silenced via management tools, it will only be disabled for the current event and will be ready to
sound again at the next event.
Silencing the Acoustical Alarm in StorCon
An option is available in StorCon under Advanced Setup ! Configure Controller, press <F4> to
silence alarm. The <F4> option is available only if the alarm has been activated.
Silencing the Acoustical Alarm in StorCon+
To silence the alarm in StorCon+, in the "Physical Configuration" view, right-click on the icon for
the controller that requires alarm deactivation. Click on "Silence" to deactivate the alarm. If the
alarm has not been activated, the "Silence" option will be grayed out and unavailable.
