Select Fault → Analysis → Test Access to access the Test Access Wizard and verify that no test access sessions exist.

If required, select Fault → Analysis → Test Access to access the Test Access Wizard and delete all existing test access sessions.

Reference:

• Procedure 14-25: Delete test access session

Important!

The original DS3/EC1/TMUX cabling may be 12-port cables or 24-port cables. The 24-port cables are required to support the LNW20 48TMUXDS3EC1 circuit packs.

Refer to office records and visually inspect the shelf to determine the original TMUX/DS3/EC1 cable type.

NOTICE Service-disruption hazard

The TMUX/DS3/EC1 12-port cables cover ports 1 - 12 on both companion circuit packs and cannot be removed or replaced without interrupting service at this time.

Do not replace the TMUX/DS3/EC1 12-port cables for ports 1 - 12 at this time.

Install the TMUX/DS3/EC1 24-port cables for the additional ports 25 through 48 only.

Important!

Local operating procedures for removing a circuit pack may vary. One method is to simply 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 remove the circuit pack.

Determine the local operating procedures for removing a circuit pack before removing the circuit pack in slot 1 of the Function/Growth group.

Important!

The circuit pack in slot 1 of the Function/Growth group must be replaced first. Perform this step to determine if the circuit pack in slot 1 of the Function/Growth group is active for transmission.

From the System View select Reports → Status Lists → Pack. Click on Shelf and click Select. Observe the value of the Switch State parameter for the required circuit pack (according to the work instructions). If the Switch State parameter is active, the circuit pack in slot 1 of the Function/Growth group is the active circuit pack for transmission. Click Close.

Important!

This step is optional. If the circuit pack in slot 1 of the Function/Growth group is the active circuit pack for transmission, then a manual switch must be performed before replacing the circuit pack.

If the circuit pack in slot 2 of the Function/Growth group is the active circuit pack for transmission, do not perform this step.

To perform a manual transmission switch, select Fault → Protection Switch. Click on the required 1+1 Equip protection group (according to the work instructions) and Select. Select the Manual (Normal) Switch Type and click Apply.

Result:

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

Replace the circuit pack in slot 1 of the Function/Growth group with the replacement LNW20 48TMUXDS3EC1 circuit pack.

Result:

If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP slot conditions when the replacement LNW20 48TMUXDS3EC1 circuit pack is inserted in the slot. After the circuit pack firmware update is complete, the system reports an unexpected CP type alarm for slot 1 of the Function/Growth group.

If a circuit pack firmware update is not required, the system reports an unexpected CP type alarm for slot 1 of the Function/Growth group when the replacement LNW20 48TMUXDS3EC1 circuit pack is inserted.

Important!

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

From the System View select Configuration → Update System → Update All.

Result:

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

The replacement LNW20 48TMUXDS3EC1 circuit pack in slot 1 of the Function/Growth group is autoprovisioned, and the system performs an automatic circuit pack protection switch. Traffic is automatically switched from the circuit pack in slot 2 of the Function/Growth group to the circuit pack in slot 1 of the Function/Growth group.

All traffic is now active on the circuit pack in slot 1 of the Function/Growth group.

The unexpected CP type alarm for slot 1 of the Function/Growth group clears, and the system reports an CP not allowed - eqpt alarm for slot 2 of the Function/Growth group.

Replace the companion circuit pack in slot 2 of the Function/Growth group with the replacement LNW20 48TMUXDS3EC1 circuit pack.

Result:

The replacement LNW20 48TMUXDS3EC1 circuit pack in slot 2 of the Function/Growth group is autoprovisioned and all alarms clear.

This completes the TMUX/DS3/EC1 circuit pack upgrade in a Function/Growth group. If the TMUX/DS3/EC1 circuit packs in other Function/Growth groups are to be upgraded at this node, repeat Step 6 through Step 11; otherwise, continue with the next step.

NOTICE Service-disruption hazard

The TMUX/DS3/EC1 12-port cables cover the ports on both companion circuit packs and cannot be removed or replaced without interrupting service.

To prevent service interruptions, traffic on ports 1 through 12 must be bridged/rolled to ports 25 through 37, respectively, before replacing the 12-port cables.

Important!

All cross-connections that are associated with ports 1 through 12 of the LNW20 48TMUXDS3EC1 circuit packs must be identified so that traffic can be moved to ports 25 through 37.

Select View → Cross-Connections. Click on the LNW20 48TMUXDS3EC1 circuit pack in slot 1 of the required Function/Growth group and Select to obtain the current list of cross-connections. Identify and record all cross-connections for ports 1 through 12. Click Close to exit.

At the local node, select Configuration → Cross-Connections and use the Cross-Connection Wizard to bridge the add cross-connections for ports 1-12 to ports 25-37, respectively on the TMUX/DS3/EC1 circuit pack in slot 1 of the required Function/Growth group.

Reference:

Procedure 10-10: Bridge and roll cross-connections

At the customer equipment connected to ports 1 to 12 at the DSX panel, bridge the corresponding cross-connections.

At the local node, select Configuration → Cross-Connections and use the Cross-Connection Wizard to roll the drop cross-connections for ports 1-12 to ports 25-37, respectively on the TMUX/DS3/EC1 circuit pack in slot 1 of the required Function/Growth group.

Reference:

Procedure 10-10: Bridge and roll cross-connections

At the customer equipment connected to ports 1 through 12 at the DSX panel, roll the corresponding cross-connections.

At the local node, replace the 12-port cables with the 24-port cables for ports 1 through 24.

Reference:

Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Installation Manual, 365-372-327

If required, repeat Step 14 through Step 18 to bridge and roll traffic back to ports 1 through 12.

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. 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.
