NOTE:
• Before changing TP Speed, Duplex Mode and Flow
Control setting, please make sure PIN 1 is set to OFF.
• If you would like to set TP Speed to 10M or 100M, please
make sure Pin 3 is set to OFF.
• The 1000Mbps supports full-duplex mode only.
• When Pin 8 is set to ON, TP speed is forced to 1000M
and full-duplex and flow control are disabled.
• Power reset must be performed after changing the dip
switch setting.
7. Link Alarm
Link Alarm feature allows users to easily identify and
diagnose the link status of TP and F/O segment. When
Link Alarm is enabled, TP and F/O ports will link up only
when both TP and F/O segment linking conditions are good.
If either TP or F/O segment is down during operation, the
other port will also shut down link to alert users and avoid
packet loss. When Link Alarm is disabled, the TP and F/O
port will link up based on their own segment linking
condition. For example, if the F/O segment is down during
operation, this device will not shut down the TP port link to
the TP segment and vice versa.
