Very Large Fabric (VLF) LNW59 OC-192 OLIU to Very Large Fabric (VLF) LNW504 multi-rate OC-48/OC-192 OLIUs

Note:

To upgrade the small fabric OLIUs (LNW26B, LNW28, LNW77, or LNW121B159B) to the VLF fabric OLIU (multirate LNW82 OC3/OC12/OC48), you must first upgrade to a large fabric OLIUs (LNW27, LNW29, LNW32, LNW76, LNW202, or LNW221–259 OC-48 OLIUs).

Important!

To upgrade the OC-n bandwidth capacity of UPSR/BLSR networks, refer to the following:

The small fabric LNW26B, LNW28, LNW77, and LNW121B–159B OC-48 OLIU circuit packs can cross-connect VT1.5 signals in up to 6 STS-1 signals or 12 STS-1 signals. If the Normal/Enhanced jumper is in the Normal position, the circuit pack can cross-connect VT1.5 signals in up to 6 STS-1 signals. If the Normal/Enhanced jumper is in the Enhanced position, the circuit pack can cross-connect VT1.5 signals in up to 12 STS-1 signals.

The small fabric LNW48, LNW50, LNW54, and LNW203 OC-12 OLIU circuit packs can cross-connect VT1.5 signals in up to 12 STS-1 signals.

The large fabric LNW27, LNW29, LNW32, LNW76, LNW202, and LNW221–259 OC-48 OLIU circuit packs can cross-connect VT1.5 signals in up to 48 STS-1 signals.

The large fabric LNW56, LNW57, LNW58, LNW502, or LNW555 OC-192 OLIU circuit packs can cross-connect VT1.5 signals in up to 48 STS-1 signals.

The Very Large Fabric LNW59 OC-192 OLIU circuit packs can cross-connect VT1.5 signals in up to 192 STS-1 signals.

The Very Large Fabric multirate LNW82 OC3/OC12/OC48 OLIU circuit packs can cross-connect VT1.5 signals in up to 192 STS-1 signals.

The Very Large Fabric multirate LNW504 OC48/OC192 OLIU circuit packs can cross-connect VT1.5 signals in up to 192 STS-1 signals.

Important!

This in-service upgrade is intended to be used with only circuit packs carrying service protected traffic.

Important!

The Very Large Fabric LNW59 and LNW82 circuit packs are only compatible with the Alcatel-Lucent 1665 DMX High Capacity Shelf (DMX-HC-20A, DMX-HC-30A, or DMX-HC-30A-CE Shelf Type). The Standard Alcatel-Lucent 1665 DMX Shelf does not support upgrades to Very Large Fabric circuit packs.

To determine the shelf type, select View → Equipment, highlight Shelf, and click Select to obtain the shelf details.

Upgrades to multiport circuit packs

When upgrading to a circuit pack with more ports, the cross-connections on the original port are mapped to the same port number on the upgrade circuit pack. The upgrade circuit pack must also be configured with compatible pluggable transmission modules that match the port signal rates on the original circuit pack.

The additional ports on the upgrade circuit pack cannot be used until after the upgrade is completed.

Upgrades and multi-shelf digital cross-connect system (DCS) systems

In multi-shelf DCS systems utilizing a single TID, the OLIU circuit packs in the Main slots of the Main shelf support the cross connect capacity upgrades.

If a shelf is configured as a subshelf of a multi-shelf DCS system utilizing a single TID, any attempt to upgrade the OLIU circuit packs in the Main slots of the subshelf will be denied.

Do not rock circuit packs back and forth when removing or installing them. Carefully slide circuit packs into or out of the shelf slot.

NOTICE

Service-disruption hazard

Removing or installing circuit packs during a System Reset can cause system errors.

Do not remove or install a circuit pack during a System Reset. If a System Reset occurs, wait until the System Reset is complete, then remove or install the circuit pack.

NOTICE

Service-disruption hazard

If upgrading to Very Large Fabric (VLF) multiport, multirate LNW82 OC3/OC12/OC48 OLIU or Very Large Fabric (VLF) LNW59 OC-192 OLIU circuit packs, transmission hits (up to 130 ms) will occur as BLSR traffic is switched and transmission hits (up to 3 seconds) will occur as traffic on LNW20 TMUX circuit packs is switched.

If upgrading from a small fabric LNW26B OC-48 OLIU to a large fabric LNW27 OC-48 OLIU, transmission hits (up to 400 ms) will occur as BLSR traffic is switched.

If the OLIU circuit packs being upgraded carry Ethernet traffic with LCAS enabled, transmission hits (up to 6 seconds) may occur as Ethernet traffic is switched.

The length of the service hits varies based on shelf equipage and TDM/Ethernet service provisioning.

Before you begin

Prior to performing this procedure:

Refer to Laser safety and Electrostatic discharge information in Chapter 1, Safety.
Obtain the work instructions for this procedure, and verify that the affected OLIU circuit pack/protection group AIDs are specified.
Review the applicable office records and verify that each fiber span is capable of supporting the replacement circuit pack/pluggable transmission module. Refer to Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300 for the SONET optical specifications of the replacement circuit packs/pluggable transmission modules.
Review the applicable Alcatel-Lucent 1665 Data Multiplexer (DMX) Software Release Description for any detailed procedures or cautions that may apply to this upgrade procedure.
If the provisioned Timing Source is external, verify that both timing references (REF-1 and REF-2) are in-service (IS) before beginning this procedure.
Determine the local operating procedures for removing a circuit pack. Local operating procedures for removing a circuit pack may vary. One method is to disconnect the optical fibers and remove the circuit pack. Another method is to verify the circuit pack active/standby status, perform manual switches if the circuit pack is active, and then disconnect the optical fibers and remove the circuit pack.

Steps

Important!

When optical fibers are disconnected during this procedure, inc. LOS, section DCC channel failed, and neighbor SYSCTL CP unavailable alarms are reported. The holdover mode active condition may also be reported depending on the provisioned system timing mode.

When optical fibers are connected in a BLSR during this procedure, Default K-bytes alarms are reported temporarily.

Complete the following steps to upgrade in-service, the cross connect capacity of the high-speed OLIU circuit packs at a node in a 1+1/UPSR/BLSR network.

Reference:

Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar^® CIT session

Using the WaveStar^® CIT verify the status of the node to be upgraded.

Reference:

Procedure 12-1.1: Verify status of node to be upgraded

If required, verify the active/standby status of the high-speed OLIU circuit pack in Main slot M1 and perform manual switches to switch traffic away from an active circuit pack.

Reference:

Procedure 12-1.2: Verify active/standby status of circuit pack to be replaced

Important!

The OLIU circuit pack in Main slot M1 must be replaced first.

Open the lower faceplate latch on the OLIU circuit pack in Main slot M1. If the circuit pack is active for timing and/or transmission, opening the latch causes timing and/or transmission switches. Disconnect the optical fibers from the OLIU circuit pack in Main slot M1. Then replace the OLIU circuit pack in Main slot M1 with the replacement OLIU circuit pack/pluggable transmission module.

Result:

Transmission hits (less than 60 ms) may occur if traffic exists on the circuit pack in Main slot M1. If through traffic exists (UPSRs and BLSRs only), transmission hits (less than 60 ms) may occur at the nodes where the traffic is added/dropped.

If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement OLIU circuit pack/pluggable transmission module is installed. After the circuit pack firmware update is complete, the system reports an unexpected CP type alarm for Main slot M1.

If a circuit pack firmware update is not required, the system reports an unexpected CP type alarm for Main slot M1 when the replacement OLIU circuit pack/pluggable transmission module is installed.

If upgrading to VLF OLIU circuit packs, the system reports a CP removed or CP failure alarm for approximately 4 minutes before reporting the unexpected CP type alarm.

For BLSR protection groups, the system also reports a Line Automatic Switch condition for Main slot M1.

Alarms may also be reported at other nodes in the network.

Reference:

Procedure 4-2: Install OLIU circuit packs in Main slots

Measure the optical receive power of the receive fiber using an optical power meter. Select the appropriate LBO to attenuate the receive signal to the middle of the allowable optical receive power range. (Refer to the Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300 for the SONET optical specifications of the OLIU circuit packs/pluggable transmission modules.)

Clean all fiber connectors, and connect the transmit and receive optical fibers to the replacement OLIU circuit pack/pluggable transmission module in Main slot M1.

Procedure 14-3: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs)

NOTICE

Service-disruption hazard

If upgrading from a small fabric LNW26B OC-48 OLIU to a large fabric LNW27 OC-48 OLIU, transmission hits (up to 400 ms) will occur as BLSR traffic is switched.

If the OLIU circuit packs being upgraded carry Ethernet traffic with LCAS enabled, transmission hits (up to 6 seconds) may occur as Ethernet traffic is switched.

The length of the service hits varies based on shelf equipage and TDM/Ethernet service provisioning.

Important!

The UPD/INIT button does not work during this upgrade.

At the System View select Configuration → Update System → Upgrade. Select main-1 (default) as the Directed Slot Choice and click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes.

The replacement OLIU circuit pack/pluggable transmission module in Main slot M1 is tested and autoprovisioned,

The system performs automatic protection switches. Transmission hits (less than 60 ms) occur as traffic is automatically switched from the OLIU circuit pack in Main slot M2 to the replacement OLIU circuit pack/pluggable transmission module in Main slot M1. All traffic is now active on the replacement OLIU circuit pack/pluggable transmission module in Main slot M1.

The unexpected CP type alarm for Main slot M1 clears, and the system reports an unexpected CP type alarm for Main slot M2.

For BLSR protection groups, the Line Automatic Switch condition for Main slot M1 clears, and the system reports a Line Automatic Switch condition for Main slot M2.

Alarms may also be reported at other nodes in the network.

Open the lower faceplate latch on the OLIU circuit pack in Main slot M2. Disconnect the optical fibers from the OLIU circuit pack in Main slot M2. Then replace the OLIU circuit pack in Main slot M2 with the replacement OLIU circuit pack/pluggable transmission module.

Result:

The replacement OLIU circuit pack/pluggable transmission module in Main slot M2 is tested and autoprovisioned.

If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement OLIU circuit pack/pluggable transmission module is installed. After the circuit pack firmware update is complete, the unexpected CP type alarm for Main slot M2 clears, and the system reports an inc. LOS alarm for Main slot M2.

If a circuit pack firmware update is not required, the unexpected CP type alarm for Main slot M2 clears, and the system reports an inc. LOS alarm for Main slot M2.

Reference:

Procedure 4-2: Install OLIU circuit packs in Main slots

Clean all fiber connectors, and connect the transmit and receive optical fibers to the replacement OLIU circuit pack/pluggable transmission module in Main slot M2.

Result:

All alarms clear and service is restored after the provisionable wait-to-restore interval elapses. (The default is 5 minutes.) This applies to the local node and the adjacent node connected to the circuit pack in Main slot M2.

Reference:

Procedure 14-3: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs)

Important!

It is recommended that the network element database be backed up to a remote OS (for example, OMS) after an upgrade. This creates a current backup copy that includes the replacement circuit packs/pluggable transmission modules. The remote OS could use this backup copy to restore the network element database in the event of a catastrophic failure. Attempts to restore the network element database using a backup copy created prior to the upgrade may result in circuit pack failures.

Back up the network element database using the Configuration → Software → Remote Backup command.

Reference:

This completes the circuit pack upgrade at the local node. If other nodes in the network are to be upgraded, repeat this procedure at each node beginning at the adjacent node connected to the circuit pack in Main slot M2.
