Alarms
The LEDs (OK, RX, and TX) on the front panel illuminate either orange or red when there is a fault
condition:
 Orange indicates a minor alarm that should not affect traffic across the link.
 Red indicates a major alarm condition that could affect traffic across the link.
A major or minor alarm can be mapped to the external alarm outputs (see “
Configuring the external
alarm outputs” on page
