T:LAN OS Upgrade Guide­lines

Incredibly, our T:LAN product line has now been on the market for two decades. Along the way, the T:LAN hardware has been updated several times. The T:LAN OS in turn has grown in size and complexity. It has gained features, a variety of optional modules and licensed enhancements.
 
This document brings together some of our best practices, guidelines and recommended procedures. Follow these when upgrading T:LAN units in your network.

Identifying T:LAN OS Editions

T:LAN OS editions can be identified by their version and release codes. Newer OS editions also added a build number:

Fields:   
   
 Version 1.MM.mmL Release CWWyy BN xxxx
   
 MMMajor version code
 mmMinor version code
 LPackage
 CCustomer release
 WWWeek
 yyYear
 xxxxBuild Number
   
Examples:  
   
 Version 1.02.20A Release C3301
 This OS has been released in the 33rd week of 2001.
   
 Version 1.04.18A Release C4405 Build 1481
 This OS has been released in the 44th week of 2005
 and carries the build number 1481.

Required Tools

Optima supplies a Windows based application called the Remote Commander Client (RCC) to facilitate OS upgrades. Specific Remote Commander Client versions are required depending on the OS a T:LAN unit is supposed to be upgraded to.

When upgrading to a newer T:LAN OS edition, please make sure to follow the guidelines outlined in the following sections.

Procedure

  1. Log into each T:LAN unit to be updated, save unsaved changes to the NVCM.

  2. Grab a copy of the current T:LAN Configuration file (*.TCF) in use.

  3. Reboot the unit to see if it comes back before applying the update. This ensures that the update process will proceed properly. TIP: Remedy any issues first if the unit does not recover from the reboot.

  4. Upload new OS.

  5. Copy & paste the RCC log messages from the lower portion of the RCC client window into a running log to keep track of your progress and the result of the operations.

OS Upgrades/Downgrades and T:LAN Configuration Files

T:LAN OS releases can handle T:LAN Configuration Files in a backwards compatible manner.

Meaning that newer T:LAN OS versions CAN load and process configuration files created with older T:LAN OS versions.

The opposite cannot be guaranteed.

Older T:LAN OS versions MIGHT NOT have the resources or the capabilities to fully process configuration files originating with newer T:LAN OS releases.

It is therefore recommended to ALWAYS upgrade T:LAN OS versions to the most current OS release before restoring a T:LAN configuration file previously in use.

Otherwise, obtain a backup copy of an older T:LAN configuration file that originated on a T:LAN OS release closer to the OS version currently loaded in the T:LAN.
