In the second method, a separate 1U chassis is required to act as the SNMP agent. The SNMP
agent allows a network management system to monitor InCell™ device(s) by telephone or
network connection using industry standard interfaces. The SNMP agent performs network
management operations such as setting configuration parameters, alarm notification and current
operation statistics. A database of the InCell™ network management information, called the
management information base (MIB), is maintained by the Agent.
In the third method, dry contact alarm terminals can be connected to a third party SCADA
system over copper wires.
