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

- Overview

Use this procedure to install OLIU circuit packs in the Main slots.

Important!

The OLIU circuit packs in the Main slots must both have the same optical line rate and VT cross-connect size. If the circuit packs in the Main slots have different optical line rates or VT cross-connect sizes, the system reports an unexpected CP type alarm and service may be impacted.

If installing LNW80 Switch circuit packs in the Main slots, refer to Procedure 4-16: Install LNW80 switch pack.

- Privilege level

You must log in as a Privileged, General, Maintenance, or Reports Only user to complete this procedure.

Required equipment

In addition to the equipment listed in Required equipment, the following equipment is also required:

  • Erasable marker or pencil

  • Optical loopback cables, LBOs, and optical fiber cleaning tools (if loopbacks are performed)

  • A deeper shelf cover (comcode 849068358) is required for shelves equipped with LNW82 OC3/OC12/OC48 and LNW504 OC-48/OC-192 circuit packs. This shelf cover provides more space to prevent fibers from touching the front cover when the cover is closed.

Use only Alcatel-Lucent Approved Class 1 SFP/XFP transceivers. Refer to the list of pluggable transmission modules in Procedure 4-15: Install pluggable transmission modules.

Refer to the Alcatel-Lucent 1665 Data Multiplexer (DMX) Installation Manual, 365-372-304, as required, when removing and/or installing pluggable transmission modules.

- Before you begin

Prior to performing this procedure:

  1. Refer to Before you begin in this chapter.

  2. Refer to Laser safety and Electrostatic discharge in Chapter 1, Safety.

  3. Obtain the work instructions for this procedure. It is especially important to know desired wavelengths and enhanced mode requirements (12 STS-1s) when applicable.

  4. Ensure that correct OLIU circuit packs are available for installation.

    The OLIU circuit packs in Main slots must have the same size VT cross-connect fabric. For example, the LNW27 and LNW29 OC-48 OLIU circuit packs have full (up to 48 STS-1s) VT mapping; therefore, they can be used together in the Main slots. If the circuit packs in the Main slots have different VT cross-connect fabric sizes, the system reports an unexpected CP type alarm.

    The following is a list of Main OLIU circuit packs grouped by switch fabric:

    • OC-12 OLIUs with 12 STS-1 switch fabric: LNW48 LNW50 LNW54 LNW203

    • OC-48 OLIUs with 12 STS-1 switch fabric: LNW26B (jumper set to enhanced) LNW28 (jumper set to enhanced) LNW77 (jumper set to enhanced) LNW121B–LNW159B (jumper set to enhanced)

      LNW26B, LNW28, LNW77, LNW121B–LNW159B OC-48 OLIUs with 6 STS-1 switch fabric (jumper set to normal) are not supported in Release 6.0.

      The LNW26B, LNW28, LNW77, and LNW121B–159B OLIU circuit packs are DA’ed and are no longer available.

    • OC-48 OLIUs with 48 STS-1 switch fabric: LNW27 LNW29 LNW32 LNW76 LNW202 LNW221–LNW259.

      LNW221–LNW259 are DA'd and are no longer available

    • OC-192 OLIUs with 48 STS-1 switch fabric: LNW56 LNW57 LNW58 LNW60 LNW502 LNW523 LNW527 LNW554 LNW555

      The LNW523 LNW527 LNW554 LNW555 are DA'd and are no longer available

    • Very Large Fabric multiport OC-192 OLIUs with 576 STS-1 switch fabric: LNW59

    • Very Large Fabric multiport multirate OC3/OC12/OC48 OLIUs with 192 STS-1 switch fabric: LNW82

    • Very Large Fabric multipor, multirate OC48/OC192 OLIUs with 576 STS-1 switch fabric: LNW504

Important!

The Very Large Fabric LNW59, LNW82, and LNW504 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 LNW59, LNW82, and LNW504 circuit packs. If LNW59, LNW82, and LNW504 circuit packs are installed in the Standard Alcatel-Lucent 1665 DMX Shelf, the system will not recognize the circuit pack as an allowable type.

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