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

	MM	Major version code
	mm	Minor version code
	L	Package
	C	Customer release
	WW	Week
	yy	Year
	xxxx	Build 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

Log into each T:LAN unit to be updated, save unsaved changes to the NVCM.
Grab a copy of the current T:LAN Configuration file (*.TCF) in use.
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.
Upload new OS.
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.

NOTE: Enterprise customers with a proper Remote Commander Server (RCS) license (RCC logging functionality enabled) can skip step 5 as the RCS automatically logs all RCC activity.

WARNING: Some Optima customers restrict the distribution of OS releases to a pre- approved OS list. These customers usually maintain their own internal OS distribution channel and have instructed Optima not to forward/supply any OS builds directly. PLEASE REFER TO YOUR OWN COMPANY POLICIES BEFORE CONTACTING OPTIMA SUPPORT.

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.
