Software Increment Release Notes
================================

Increment ID:   ACN18N16
Date created:   2/09/2001


Title:
------
Expand Upgrade Capabilities of the Loopback Access Interface Card (LAIC) and 
its CPLD.


Warnings:
---------
1. The 'CPLD.tar' tool for AN16.10 must be implemented on the OPC prior to 
   querying or upgrading the CPLD.  This tool can be downloaded from the 
   AN16.10 Tools web page.  Please refer to the Special Instructions below.

2. The LAIC CPLD on AccessNode Express Configurations must be upgraded manually 
   using the procedure in the Test Instructions.
  

Detailed Description of Increment:  
----------------------------------
1. This increment allows the user to view what Version CPLD load they have
   on their LAICs. 

2. This increment allows the user to upgrade their CPLD load to Version 3 
   and ensures compatibility with future versions.


System Configuration / Shelf Type Requirements:
-----------------------------------------------
This increment must be applied to all AN16.10 AccessNode configurations 
and shelf types.  This increment affects the Active Processor Unit (APU).


Prerequisite Increments Required:
---------------------------------
Increments ACN01N16 - ACN17N16 must be successfully applied prior to 
application of this increment.


Loads Affected:
---------------
APU: ACCL16DI.LD


Special Instructions:
---------------------
The 'CPLD.tar' file contains the Version 3 CPLD load and improves the 'lasaldmp'
tool.  The file should be placed in the /tmp directory on the OPC.  The following 
procedure must be done on both the active and inactive OPC BEFORE executing the
Test Instructions:

1.  Place the CPLD.tar file on the OPC in the /tmp directory.
2.  Untar the CPLD.tar file using the following command on the 
    OPC while in the /tmp directory:

    opc> tar xvf CPLD.tar

3.  Execute the CPLD installation script by typing the following command:

    opc> cpldswi

4.  If there is a backup OPC, you must install the file on that OPC as well.
    It will not be copied over automatically.


Installation Instructions:
--------------------------
Please refer to the Incremental Software Delivery Users Guide for general 
installation instructions.  This document may be obtained from either the 
AccessWeb ISD web site (https://www23.nortelnetworks.com/ACCESS_OPTICAL/esd/),
where the AccessNode increments are located, or you may order it through your 
Nortel Account Manager or Order Manager.  The document number for the 
Incremental Software Delivery Users Guide is P0934362.


Test Instructions:
------------------

Note: Only execute these Test Instructions for the AccessNode Express 
configurations within your OPC's span of control.

A. Apply the patch and make sure both LAIC cards are In Service (IS).

B. The LAIC to be upgraded must then be placed Out Of Service (OOS).

C. Upgrading the LAIC boot load:
   1. At the NE, under the ANXUPGCI tool, enter the following command:
  
      >upgrade laic <group> boot
  
      where <group> is the letter of the LAIC being upgraded: A or B.  
      Confirm the upgrade by entering 'yes'. 
   2. Use the 'LAICSTATUS' command to monitor progress.  It should only 
      take a minute or two.

D. Checking the CPLD load version:
   1. At the NE, type in 'LAICCPLD'.  This will display the CPLD load version
      for the LAIC in question.
   2. If the CPLD load is a version 1 or 2, then an upgrade will be necessary.
      
E. Upgrading the CPLD load to Version 3:
   1. At the NE, under the ANXUPGCI tool, upgrade the CPLD by entering the 
      following command: 
      
      >upgrade laic <group> cpld 
      
      where <group> is the letter of the LAIC being upgraded: A or B.
      Confirm the upgrade by entering 'yes'.  
   2. The 'LAICSTATUS' command can be issued to monitor the progress of the 
      CPLD upgrade.  The upgrade will take approximately 10 minutes.
   3. Once the upgrade is complete, type 'LAICCPLD' to verify that the CPLD
      load is Version 3.  
   4. Now change the upgraded LAIC back to IS at the LAIC equipment screen.  
      This might take a few minutes.  
   5. If the other LAIC is also going to be upgraded, make sure the upgraded 
      LAIC has been IS for at least two minutes and then place the other LAIC 
      OOS.  Then start over from Step C.
      
- These instructions will have to be implemented individually on each 
  AccessNode Express configuration within your OPC's span of control.
