This chapter covers identifying fault conditions and determining corrective action.
The front panel LEDs provide both normal and fault information. For a description of all LED func-
tions and indicators, see Table 2-4, Table 2-5, and Table 2-6.
5.1 Optical Power Loss
Whenever there is a significant signal loss, the Rx indictor turns off. Check cable integrity, and
remove and inspect the cable connectors, being careful not to damage the fiber end-face surface
or the connector housing. Clean all optical connectors before reinstalling them.
5.2 Fault Conditions
The 9145EMP front panel and interface module LEDs show fault conditions. Additional informa-
tion about fault conditions appears on the System Alarms Log. Use the System Alarms Screen to
view alarms and faults on the 9145EMP. (For more details, see the 9145EMP NID Software
User’s Manual.)
5.3 Running Diagnostics
When you set up a new connection, you can verify the link connectivity using PING prior to send-
ing data.
5.3.1 PING Testing
You can verify network connectivity with another IP device within the subnet by sending a PING
to the IP address for that device. For PING testing instructions, see the 9145EMP NID Software
User’s Manual.
