• Depending on the product model, the host unit (Host PCIx Card) may,
in addition, have a secondary fiber (connected to host Port 3) to
provide a diversity gain option. In this case, the secondary fiber will
carry a secondary reverse path from a secondary antenna.
Synthesizer alarms also refer to the primary forward path, primary reverse path,
and secondary reverse path because the host unit has a separate synthesizer for
each of these paths. The synthesizers are monitored independently; an error
condition in one synthesizer will not affect the others.
Figure 64 shows the Host window. Table 13 describes the optics alarms when
failed. Table 14 describes the synthesizer alarms and band alarm when failed.
Table 16 describes the band indicator.

ALARM NAME DESCRIPTION
Pri Laser Fail The forward path primary fiber laser is not sending
light (no light from host unit to remote unit).
Pri Rx Light No light is being received from the primary fiber (no
light from remote unit to host unit).
Pri Rx Errors Multiple errors are occurring on primary fiber. Error
rate has exceeded 10
