Service-disruption hazard

Log in to the node where the unprotected LNW70 100/1G FXS circuit pack is to be replaced.

Reference:

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

Click the Alarm List button in the top right corner of the System View to view the NE Alarm List and verify that no alarms are present.

Refer to the appropriate trouble-clearing procedures to clear all existing alarms before continuing with this procedure.

Important!

To minimize the length of the service outage when the replacement LNW170 circuit pack is installed, it is recommended that the required software be preloaded on the replacement LNW170 circuit pack (optional).

Install the replacement LNW170 circuit pack in an empty Function/Growth slot in the shelf or in another shelf running the same software version.

Result:

If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement LNW170 circuit pack is installed. The circuit pack firmware update and initialization takes approximately 5–8 minutes.

If a circuit pack firmware update is not required, the circuit pack is initialized. The circuit pack initialization takes approximately 90 seconds.

Reference:

Procedure 4-14: Install Gigabit Ethernet circuit packs

When the circuit pack firmware update and initialization is complete, open the faceplate latches on the replacement LNW170 circuit pack and remove the circuit pack from the shelf.

Result:

The system reports a CP removed alarm.

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

Result:

The CP removed alarm clears.

NOTICE Service-disruption hazard

A service outage will occur when the fibers, pluggable transmission modules, or LNW70 circuit pack are removed from the shelf until the replacement LNW170 circuit pack and pluggable transmission modules are installed with fibers reconnected.

The length of the service outage is minimized if the replacement LNW170 circuit pack is preloaded with the required software and the pluggable transmission modules/fibers are disconnected/moved from the LNW70 circuit pack to the replacement LNW170 circuit pack while the replacement LNW170 circuit pack is downloading software (if needed) and initializing.

Open the faceplate latches on the LNW70 circuit pack. If possible, remove the LNW70 circuit pack without disconnecting the pluggable transmission modules and fibers. If necessary, only remove the pluggable transmission modules and fibers required to remove the LNW70 circuit pack.

Result:

The system reports a CP removed alarm.

Install the replacement LNW170 circuit pack. While the replacement LNW170 is downloading software (if needed) and initializing, disconnect the pluggable transmission modules/fibers from the LNW70 circuit pack and clean/connect to the replacement LNW170 circuit pack.

Result:

If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement LNW170 circuit pack is installed. The circuit pack firmware update and initialization takes approximately 5–8 minutes. After the circuit pack firmware update and initialization is complete, the replacement LNW170 circuit pack/pluggable transmission modules are autoprovisioned and the system reports an unexpected CP type alarm.

If a circuit pack firmware update is not required, the circuit pack is initialized. The circuit pack initialization takes approximately 90 seconds. After the circuit pack initialization is complete, the replacement LNW170 circuit pack/pluggable transmission modules are autoprovisioned and the system reports an unexpected CP type alarm.

Transmission is now supported on the replacement LNW170 circuit pack.

• Procedure 4-16: Install pluggable transmission modules

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

Important!

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

At 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 LNW170 circuit pack/pluggable transmission modules are tested and the unexpected CP type alarm clears.

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.

Reference:

• Procedure 2-9: Backup and restore NE database using SFTP

• Procedure 2-10: Backup and restore NE database via FTP

• Procedure 2-11: Backup and restore NE database via FTTD

• Procedure 2-12: Backup and restore NE database via FTAM

This completes the circuit pack upgrade. If required, repeat this procedure to upgrade another LNW70 circuit pack.
