Alarm Types

The VNE 250 and VND 250 generate alarms in response to a range of error conditions.

Alarm Handling

If there is a critical alarm, the front panel Alarm LED lights red. The rear panel relay contacts

also close.

Alarms are reported on the following interfaces:

z Web User Interface Alarms tab (page 37) and Alarms Logs tab (page 38).

z Front panel alarm LED (see figure 5,

2

on page 11).

z SNMP traps (version 3) (see Overview — SNMP on page 39).
