be affected.

Figure 2.9 Application with LinkLoss and FiberAlert Disabled

As shown in Figure 2.10, using the same application, if LinkLoss is

enabled on the near side and FiberAlert is enabled on the far side,

the near side will be notified of any fiber link faults on the far side,

Figure 2.10 Application with LinkLoss and FiberAlert Enabled

Troubleshooting with LinkLoss and FiberAlert

If LinkLoss is enabled and you lose the connection between the

SNMP Media Converter and the hub/switch the SNMP Media
Converter is connected to, disable LinkLoss to assist in pinpointing
