Common Applications for the NetGuardian 8A
The NetGuardian 8A reports alarms as SNMP traps over LAN and supports DCP polling over RS-232, RS-485 or
LAN. The NetGuardian 8A supports simultaneous SNMP and DCP operation.
The NetGuardian 8A supports both LAN and serial port connectivity. The LAN connection and serial port can be
used at the same time to support simultaneous SNMP and DCP alarm reporting. However, only one DCP channel
can be used, therefore the NetGuardian 8A cannot simultaneously report DCP over LAN and DCP over serial port
connection.
In addition to its 4 discrete input points, the NetGuardian 8A has 2 control relays, all form C, user defined NO/NC
with shunts, 8 analogs, and dwire. The control relays allow network administrators to respond remotely to threats to
system integrity. Using the control relays, network administrators can turn on backup generators, open doors and
gates for emergency access, reboot equipment, or perform other functions. The NetGuardian 8A also allows you to
reverse the logic state of the alarm on a point by point basis for discrete alarms.
Another feature of the NetGuardian 8A is user-defined alarm qualification times. This will allow you to clearly
distinguish momentary status changes from serious problems.
