4.8.1 OSM/ESM Fault Mask
Figure 4-12 shows the Fault Mask window.
Figure 4-12 OSM/ESM Fault Mask Window
The fault mask is used to specify which fault states are monitored by the
OSM/ESM and lead to the signaling contact being triggered and the fault LED
being lit.
The fault mask can also be set using the buttons on the front panel of the
OSM/ESM, see /1/.
Enable Power Monitoring
This specifies which of the two power supply lines 1 and 2 is monitored. A fault is
indicated by the signaling contact when there is no power on one of the monitored
lines (line 1 or line 2) or when the voltage is too low (less than 14 V).
Enable Link Status Monitoring
This enables/disables the link monitoring for ports 1 to 4 or 1 to 8. If the monitoring
is activated on one of the ports, a fault is signaled (fault LED, signaling contact)
when there is no valid link at this port (for example cable not plugged in or
connected device turned off).
