X-300/X-400 Fault Mask
Function of the fault mask
With the fault mask, you specify the fault/error states to be monitored by the IE switch and
that will trigger the signaling contact. Possible fault/error states are the absence of the power
supply, power supply too low, or an interrupted connection or an unexpected connection
established to a partner device. If the signaling contact is triggered, this causes the fault LED
on the device to light up and, depending on the configuration of the event table, can trigger a
trap, an E-mail, or an entry in the log table.
Device-related link monitoring of the ports
An IE switch provides device-related link monitoring. A link-up or link-down also affects the
message system if the IE switch was appropriately configured.
Setting the fault mask on the device
The fault mask can also be set by the using the SET/SEL button on the front panel of the IE
switch; for more detailed information, refer to the "Operating Instructions SCALANCE X-400
Industrial Ethernet Switches".
Settings in WBM
In WBM, you can set the monitoring of the power supply and the device-related link
monitoring. The settings are made in three separate masks:

Enable Power Monitoring
Here, you specify which of the two power supply lines 1 and 2 is monitored. A fault is then
indicated by the message system 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).
