prompt the received alarms and the alarm severities.
Alarm indicator: The four alarm severities are represented by different
colors, namely yellow, orange, blue, and red (listed from high to low).
Alarm server indicator: The alarm box panel provides 10 alarm server
indicators representing 10 group of alarm servers (generally it is
recommended that one indicator represent one server). Each indicator
shows the link status and the alarm status for a specific group of server
servers.
LCD display: The alarm information sent from the alarm server is
displayed on the LCD screen of the alarm box. Moreover, the alarm box
menu and keys on the panel are available to configure the working
parameters, for example, the IP address, UDP port, key tone control,
and backlight control.
Remote deployment: An alarm server can be connected to both local
and remote alarm boxes. In the case of remote alarm boxes, routing
information should be configured in the alarm box. Remote deployment
allows more flexible usages of alarm boxes. For example, the alarm box
can be deployed in the office rather than in the equipment room.
Multi-office-in-one: Up to 128 alarm servers can be configured on an
alarm box, and up to 10 groups of alarm servers can be simultaneously
connected to an alarm box. The alarm servers may reside in different
network segments, and therefore the multi-office-in-one function is
employed together with the remote access function.
Cross-VLAN alarming: The alarm box can be simultaneously connected
to alarm servers from different VLANs. In this scenario, a layer-2 switch
rather than a layer-3 device is deployed to achieve VLAN isolation,
reducing the networking cost.
Broadcast storm detection and alarming: Thresholds can be configured
to detect the network status and avoid network congestion caused by
data broadcasting.
Group-based alarm acknowledgement: Alarms can be acknowledged on
a per-group basis as alarm servers can be classified into groups, and
