Configuring the Port Monitor
Figure 18 displays the features of the Port Monitor which can watch each port for a fault
condition specific to that port. The portion of Figure 18 shown outlined in red will be
unavailable (dimmed) for models EISC12-100T/FC and EISC12-100T/FT.

Setting the Fault Relay
At the bottom of the Port Monitor window shown in Figure 18 there are four Fault Relay
settings: “Port Monitoring” must be enabled for the relay to function. The user may
choose for the relay to either “make” or “break” on fault. Following power up, the relay
action can be delayed for up to 999 seconds. Finally, the user can elect to reset the
relay manually or have it reset automatically once the fault clears.
For convenience, Port Monitoring can also be controlled from the bottom of the main
Configurator panel where the relay state is reported and where faults can be cleared
and the relay manually reset (if enabled).
Each port can be monitored for one of three options shown in
Figure 19. The default setting is for the Port Monitor to “Ignore”
the situation of a given port. If the user chooses the “No Link”
option, the monitor will report a fault if proper link pulses are not
received by the given port. Selecting the “Link Present” option
provides a means for alerting the network administrator if an
unauthorized link has been established.
