3.2 Alarms

The 9155 can generate Major and Minor Alarms. For details about the Alarm Output Configuration,

Alarm Log, and Trap Configuration screens, see Chapter 4.

3.2.1 Remote Fault

If the Extension port Rx loses the signal, it sends a Remote Fault (RMTF) signal from its Tx, the Rx

LED is off, and an alarm flags the link loss on the Extension port. When the Extension port receives

a Remote Fault signal, the Rx LED lights red and an alarm flags the remote side optical link failure.

See Figure 2. Both local and remote link partners must be configured to the same RMTF

enable/disable setting. To set RMTF in software, see Section 4.7. RMTF complies with the

IEEE802.3u Remote Fault standard.
