Comments

15454-TCC+=

Shipped between 11/19/00 and 9/14/01

Serial Numbers

From FAA0437xxxx To FAA0452xxxx

Problem Description

TCC+ boards shipped from the factory with software version 2.2.1, 2.2.2, 3.0.0 or 3.0.1 pre-loaded may have flash memory that was incorrectly formatted during initialization, resulting in incorrect block size definitions. This condition will prevent the loading of software files, resulting in the failure of specific cards to complete the initial boot up process.

Background

Due to a manufacturing process software change, boards manufactured between the above dates were programmed with a procedure void of a necessary initialization routine. The result of this change is the possibility of incorrectly formatted block size in the boards flash memory.

This issue is self-correcting when a software upgrade is performed to version 2.2.1 and later. This is true even if the software upgrade is done with the currently installed software version.

Problem Symptoms

Some installed boards may not complete the boot process due to missing or corrupt files on the TCC+.

Workaround/Solution

A software script has been written to test for this condition. If you are a registered user and are logged in you may go to Software Download (registered customers only) and download the script ptaudit.exe. This script may also be obtained by contacting the TAC. Please see For More Information at the end of this document.

By running this script file, both the primary and protect TCC+ will be checked for this condition. If flash memory corruption is found, it will be reported back to the operator. The script takes about one minute to run. Instructions for running the script are included with the script file.

Note:?DO NOT REMOVE THE TCC+ OR OTHERWISE DISRUPT THE SOFTWARE DOWNLOAD PROCESS DURING THIS OPERATION.

To correct the corrupted flash condition if found, perform a software upgrade to the affected TCC+ using revision 2.2.1 or later. This may be done even if the currently loaded version matches that of the upgrade.

If you purchased your system with pre-loaded software and you do not have a working copy, you may obtain a copy by contacting your account representative.
