Procedure 6-28: Replace DWDM optical multiplexer/demultiplexer circuit pack
Before you begin
Prior to performing this procedure:
-
Refer to Required equipment in this chapter.
-
Refer to Electrostatic discharge in Chapter 1, Safety.
-
Ensure that the appropriate circuit pack is available for replacement.
Steps
Complete the following steps to replace an Ethernet/Data circuit pack.
1 |
If required, remove the cables from the circuit pack. |
2 |
Remove the required circuit pack by grasping the inner edge of the locking-levers, and applying a constant pressure, pull the levers forward and remove the circuit pack. |
3 |
Ensure that all optical fiber connectors and couplings are properly cleaned on the replacement circuit pack. Important! Signal performance may be degraded if the connections and couplings are not cleaned properly. Reference: Procedure 6-11: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs) |
4 |
Holding the replacement circuit pack vertically, rotate the replacement circuit pack 90 degrees to the right (clockwise). The faceplate label with LNW785 should be on your right, next to the fan unit. |
5 |
Seat the replacement circuit pack in vacant Function Unit slot. Result: FAULT LED on the circuit pack lights. After approximately 60 seconds, the ACTIVE LED lights and the FAULT LED goes off. (Firmware updates may take place that add additional wait time.) Select View → Refresh System View and the circuit pack appears in the WaveStar® CIT System View indicating successful installation. If both the original circuit pack and the replacement circuit pack fail when no other transmission circuit packs are installed in the shelf, replace the SYSCTL circuit pack. Refer to Procedure 6-10: Upgrade or replace SYSCTL (LNW2) circuit pack. |
6 |
If required, reconnect the cables. Result: The circuit pack FAULT LED stops flashing. |
7 |
Ensure that a 177D apparatus blank or an LNW98 Detectable apparatus blank is present in the unequipped companion Function Unit slot. |
8 |
From the System View menu, click the Alarm List button to obtain an NE Alarm List. Verify that no alarms are present for the installed circuit pack. If required, refer to the appropriate procedure to clear any alarms. |
9 |
From the System View menu, use View → Equipment to access the circuit pack/port parameters for the circuit pack just installed and verify that the parameters are intact. If required, refer to the appropriate procedure in the Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) User Operations Guide, 365-372-325 to change any circuit pack/port parameters.
