Link Alarm
The link alarm feature allows users to easily identify and diagnose the link status for TP and fiber optic
segments. 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 the link to alert
users and avoid packet loss. When the 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 segment and vice versa.
Troubleshooting
If trouble is encountered, verify all copper and fiber connections and settings. Refer to the LED Indicators
at the front of the card. They show availability of power, modes of operation, and data being received by
the fiber and TP port. If trouble persists, replace the unit and retest. If technical assistance is required,
