Determine the circuit pack and socket being equipped with the pluggable transmission module.

Important!

Do not remove the dust cover unless you are ready to connect fibers or if you need to clean the pluggable transmission module.

Hold the optical connector/latch-end of the pluggable transmission module in your left hand with the gold fingers facing you. The pluggable transmission module should be positioned in a manner similar to Figure 4-1, Pluggable transmission module with dust cover.

Figure 4-1: Pluggable transmission module with dust cover

Dust covers

There are a variety of different types of dust covers. Any of the following examples could be similar to the dust cover in your pluggable transmission module.

Figure 4-2: Examples of dust covers

Refer to the following figure and determine the type of latching mechanism on the pluggable transmission module.

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 pluggable transmission module.

Reference:

Procedure 14-19: Clean pluggable transmission module

If required, remove the dust cover from the required socket on the circuit pack faceplate.

Referring to Step 3, what type of latching mechanism does the pluggable transmission module have?

Before inserting the pluggable transmission module, the swivel latch must be in the closed position. With the dust cover in place, the swivel latch is in the closed position.

The following figure shows the open and closed position of the swivel latch. Depending on the PTM type, the port opening and latch mechanism may vary.

Figure 4-3: Latch type 3 (swivel latch opened and closed)

Proceed to Step 10.

Before inserting the pluggable transmission module, the swivel latch must be in the closed position. With the dust cover in place, the swivel latch is in the closed position.

The following figure shows the open and closed position of the latch. Depending on the PTM type, the port opening and latch mechanism may vary.

Figure 4-4: Latch type 4 (swivel latch opened and closed)

With your left hand, hold the pluggable transmission module by the dust plug (optical) or port end (electrical). The ports are in your left hand and the gold fingers are visible (facing you). (Do not insert pluggable transmission module.)

Rotate the pluggable transmission module; the dust cover is facing you and the gold fingers are facing the floor.

Push on the dust cover to insert the pluggable transmission module in the required socket of the circuit pack faceplate. (Refer to Figure 4-5, Example of inserting a pluggable transmission module into a socket (rack-mounted shelf).) The latch automatically catches when the pluggable transmission module is inserted.

To verify that the pluggable transmission module is properly latched in the cage, gently pull the pluggable transmission module (parallel to the direction the pluggable transmission module was installed). Do not rotate the swivel latch or activate the de-latching feature on the pluggable transmission module.

The pluggable transmission module is secure. Verify that all unused sockets on the circuit pack are equipped with dust covers.

Result:

If a pluggable transmission module fails when inserted into the VLNC50/52/55 circuit pack, select View → Equipment to access the port and verify that the port Signal Type parameter is provisioned the correct value (OC3/STM-1 is the default). If required, select Configuration → Equipment to access the required port and provision the port Signal Type parameter to the correct value to clear an unexpected or failed Pluggable Transmission Module alarm.

Refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Maintenance and Trouble-Clearing Guide.

Test each optical port for proper operation.

1. Select Configuration → DCC Terminations to access the first port and provision the Termination State as disabled to prevent DCC-related alarms. Click Apply and Close.

2. Loop back the port to test port functionality. Refer to Procedure 14-6: Connect optical loopback.

3. Remove the lightguide jumper used to loop back the port and the LBO, if required. Verify that the circuit pack FAULT LED and port LED associated with the pluggable transmission module start flashing. The MN/ABN LED on the SYSCTL circuit pack lights green.

4. Click the Alarm List button to obtain the NE Alarm List and verify that the inc. LOS alarm is associated with the port being tested.

5. If required, reinstall the dust cover into the port on the pluggable transmission module to maintain cleanliness.

6. Select Configuration → Update System → Update All Click Yes.

Repeat this step for all optical ports being tested.

From the System View window, click the Alarm List button to obtain the NE Alarm List. Verify that no alarms, protection switches, protection switch lockouts, and loopbacks are present for the ports on the circuit pack just installed.

Result:

No alarms should be present for the ports just installed.

If required, repeat this procedure to install additional pluggable transmission modules.

Important!

When a pluggable transmission module is installed in the VLNC6x circuit pack, the speed (rate) of the pluggable transmission module is not automatically detected. The port speed must be provisioned using the speed all command.

If required, log in to the VLNC6x circuit pack and provision the speed of both Ethernet interfaces to either 100 (100 Mbps) or 1000 (1 Gbps) using the speed all command.

Example:

(Config)# speed all 1000.
