Audible and LED Alarm Notification Operation
11.2
When a reportable event occurs, like an SNMP trap or an ASCII page, the speaker will sound and the LEDs will
blink. The speaker and LEDs will auto-acknowledge in the time specified by Sound On Time in the NetGuardian.
See Section 8 for more information on configuring the Sound On Time settings via NGEdit or the Web Browser.
You may also acknowledge an event by using the BSU II ACO knowledge button or any push button on the front
panel of the NetGuardian. Once acknowledged, the Alarm LED will remain on or off, but it will no longer blink.
When the Alarm LED is on, there may be one or more reportable events remaining in the alarm state — clearing
these alarms will turn the LED off.
Note:
Only alarms associated with a notification device are reported to the BSU II.
NetGuardian System Alarm
11.3
If communication is lost or not established with the BSU II, the NetGuardian will set a system alarm. The first
three addresses have granular system status:
59
GLD/BSU 1
60
GLD/BSU 2
61
GLD/BSU 3+
BSU II addresses above three are logically ORed with system alarm 61 as designated by the "+" — see Figure
11.1.
Fig. 11.1
Monitor the alarm status of your BSU II via the Web Browser in the Monitor > System Alarms screen.
