If required, verify the active/standby status of the non-VLF OC-48 OLIU circuit pack in Main slot M1 and perform manual switches to switch traffic away from an active circuit pack.

Reference:

Procedure 12-19.2: Verify active/standby status of circuit pack to be replaced

Important!

The Ring Upgrade Mode is required for cross-connections and provisioning data to be mapped to the replacement circuit pack.

At the WaveStar^® CIT System View, select Configuration → Ring Upgrade Mode.

Result:

A dialog box appears asking you to confirm changing the NE Mode to Ring Upgrade Mode. Click Yes.

The ABN LED is lighted on the SYSCTL circuit pack faceplate and the WaveStar^® CIT Alarm List shows the Ring Upgrade Mode as Not Alarmed.

For more information about the Ring Upgrade Mode, refer to Ring Upgrade Mode.

Important!

If the circuit pack is active for timing and/or transmission, opening the latch causes timing and/or transmission switches. Transmission hits (less than 60 ms) will occur for each separate protection switch.

Open the lower faceplate latch on the non-VLF OC-48 OLIU circuit pack in Main slot M1. Disconnect the optical fibers from the non-VLF OC-48 OLIU circuit pack in Main slot M1. Then replace the non-VLF OC-48 OLIU circuit pack in Main slot M1 with the replacement VLF OC-192 OLIU circuit pack.

Result:

The system reports the Waiting for Download and Install Program IP conditions when the replacement VLF OC-192 OLIU circuit pack is inserted in the slot. After the circuit pack firmware update is complete, the system reports an unexpected circuit pack type alarm for Main slot M1.

The FAULT LED may light on the circuit packs in the Main slots, and the opposite end of the optical spans may report inc. OCN sig. degrade (BER) and section DCC channel failed alarms.

If the provisioned system timing mode is External, the system may also report an inc. DS1 sync. ref. OOL alarm.

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

At both ends of the optical span to be upgraded, perform the following to connect the replacement VLF OC-192 OLIU circuit pack in Main slot M1 and the required VLF OC-192 circuit pack/port at the opposite end of the upgraded OC-192 optical span:

1. Clean and connect the transmit optical fibers.

2. Measure the optical receive power of the receive fibers 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 OC-192 circuit packs.)

3. Clean and connect the receive fibers.

Result:

At the opposite end of the upgraded OC-192 optical span, the inc. OC192 LOS alarm clears.

Procedure 14-4: Perform connection and verification of optical facility

NOTICE Service-disruption hazard

Transmission hits (up to 3 seconds) will occur as traffic on LNW20 TMUX circuit packs 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 system performs an automatic path protection switch, and all traffic is now active on Main slot M1. Transmission hits (less than 60 ms) occur as traffic switches from the circuit pack in Main slot M2 to the circuit pack 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. Alarms may also be reported at other nodes in the ring.

Transmission is now supported on the upgraded optical span between Main slot M1 and the required VLF OC-192 circuit pack/port at the opposite end of the upgraded OC-192 optical span.

NOTICE Equipment damage hazard

If an OC-192 OLIU circuit pack is connected to an OC-48 OLIU circuit pack equipment damage may occur.

Do not reconnect the optical fibers until instructed to do so. The optical fibers are reconnected after the OC-48 OLIU circuit pack is upgraded at each end of the optical span.

Open a faceplate latch on the non-VLF OC-48 OLIU circuit pack in Main slot M2. Disconnect the optical fibers from the non-VLF OC-48 OLIU circuit pack in Main slot M2. Then replace the non-VLF OC-48 OLIU circuit pack in Main slot M2 with the replacement VLF OC-192 OLIU circuit pack.

Result:

The system reports the Waiting for Download and Install Program IP conditions when the replacement VLF OC-192 OLIU circuit pack is inserted in the slot. After the circuit pack firmware update is complete, the unexpected CP type alarm for Main slot M2 clears, and the system reports an inc. OC192 LOS alarm for Main slot M2.
