Alarms

The VNC 325 generate alarms for range of error conditions, defined in the “Alarm types
and descriptions“ section. Alarms can be monitored at a number of locations throughout
the network interface as identified below:
• Alarms page (see figure 49, below) — The list immediately beneath the filter settings
panel details the alarm conditions that are currently active on the system.
• Alarm Logs page (see figure 51) — This page provides a historical log of when an
alarm condition was raised and cleared.
• Device list page (see figure 16) — A “traffic light” symbol in the Status column
represents the status of a device.
• In the top right hand corner of each network interface page —
The device status and system status is displayed.
In addition, the red LED located on the front panel of the codec illuminates whenever a
critical alarm is triggered.
Alarm conditions, once triggered, remain active until 5 seconds after the error that caused it
has cleared.

Alarms Page

The alarms page (see figure 49) lets you monitor system alarms and define what is and is not
