Procedure 6-22: Replace VLNC35 Fast Ethernet circuit pack
Overview
Use this procedure to replace the VLNC35 Fast Ethernet 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 the VLNC35 Fast Ethernet circuit pack.
1 |
Important! The VLNC35 Fast Ethernet circuit pack may be equipped with up to two pluggable transmission modules. If required, disconnect the optical cables and remove any pluggable transmission modules from the circuit pack. Reference: Procedure 6-6: Replace pluggable transmission module |
2 |
Remove the 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. |
3 |
Ensure that all optical fiber connectors and couplings are properly cleaned on the replacement Ethernet circuit pack. Important! Signal performance may be degraded and the fiber interface surfaces damaged if the connections and couplings are not cleaned properly. Reference: Procedure 6-17: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs) |
4 |
Important! Pluggable transmission modules are shipped with a dust plug installed into the optical ports to maintain cleanliness during storage and/or transportation. It is recommended that the dust plug 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 pluggable transmission module. Reference: Procedure 6-18: Clean pluggable transmission module |

Perform the following:
Result: A firmware Smart Apply may begin (this is indicated by a blinking ACTIVE LED). The Smart Apply may take from 5-8 minutes and the user should wait for it to complete. If the Smart Apply does not occur, the FAULT LED on the circuit pack lights. After approximately 100 seconds, the ACTIVE LED lights and the FAULT LED goes off. The replacement 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. |
6 |
Important! The VLNC35 Fast Ethernet circuit pack may be equipped with up to two pluggable transmission modules. If required, install the pluggable transmission modules and reconnect the optical cables. Reference: Procedure 6-6: Replace pluggable transmission module |
7 |
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. |
8 |
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 |
