Setting the FibeAir2000 Manager Language
In the dialog of Figure 9-20 , you can set the FibeAir2000 Manager inter-
face language, where other localizations are available.
Setting SNMP Parameters
Use these choices to set the SNMP monitoring interval and time-out. These
are only significant if you are using an SNMP based network management
system.
Remote Power Fail Indication
Remote power fail indication indicates to one side that the other side has
suffered a power failure. The failed site sends a final trap indication about
the power loss just before powering off.
A “Dying-Gasp” circuit identifies the power failure at a minimum interval of
20 milliseconds before the ODU or IDU powers off. During that interval a
message notifying the power failure is sent to opposite site. External alarm
output number 4 indicates power failure at the opposite site.
Troubleshooting
Use the following table to troubleshoot LED fault indications:
