Procedure 6-4: Replace VLNC5x SONET/SDH transport circuit pack
Required equipment
In addition to the equipment listed in Required equipment, optical loopback cables, LBOs, and optical fiber cleaning tools may also be required if loopbacks are performed.
Refer to the list of Class 1 SFP transceivers that are approved by Alcatel-Lucent in Procedure 6-6: Replace pluggable transmission module.
Refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Installation and System Turn-Up Guide, as required, when removing and/or installing pluggable transmission modules.
Before you begin
Prior to performing this procedure:
-
Refer to Laser safety and Electrostatic discharge information in Chapter 1, Safety.
-
Ensure that the correct replacement circuit pack is available for replacement.
-
If required, ensure that the correct pluggable transmission modules are available for replacement.
Steps
Complete the following steps to replace a VLNC5x circuit pack.
1 |
Remove the optical fibers from the circuit pack. |
2 |
If required, remove any pluggable transmission modules from the circuit pack. Reference: Procedure 6-6: Replace pluggable transmission module |
3 |
Remove the required circuit pack by grasping the inner edge of the locking lever, and applying a constant pressure, pull the lever forward and remove the circuit pack. |
4 |
Important! Signal performance may be degraded and the fiber interface surfaces damaged if the connections and couplings are not cleaned properly. Ensure all optical fiber connectors and couplings are properly cleaned on the replacement circuit pack. Reference: Procedure 6-17: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs) |
5 |
Important! Pluggable transmission modules are shipped with a dust cover installed into the optical ports to maintain cleanliness during storage and/or transportation. It is recommended that the dust cover be kept in place to maintain cleanliness until the optical fiber is connected. With proper care and handling, cleaning the pluggable transmission modules should not be necessary. If required, clean the optical pluggable transmission module. Reference: Procedure 6-18: Clean pluggable transmission module |
6 |
Perform the following:
|
7 |
Secure the circuit pack in the shelf using the latch lever. Result: The circuit pack FAULT LED lights for approximately 2 minutes then goes off, indicating successful installation. The circuit pack appears in the WaveStar® CIT System View. 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 6-3: Upgrade or replace a SYSCTL (VLNC2) circuit pack. |
8 |
Important! The VLNC5x circuit pack may be equipped with up to three pluggable transmission modules. If required, install pluggable transmission modules. Reference: Procedure 6-6: Replace pluggable transmission module |
9 |
If required, reconnect the optical fibers. Result: The circuit pack FAULT LED and port LED associated with the pluggable transmission module stops flashing. |
10 |
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. |
11 |
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 1850 Transport Service Switch (TSS-5) User Provisioning Guide to change any circuit pack/port parameters. End of steps |
