Upgrading System Software

Before Downloading the T1000.Z File

The Tasman Networks command line interface (CLI) provides commands that allow you to
upgrade the Model 1002 and Model 1004 router with new software. Every system is furnished
with a software image file (T1000.Z) and a boot image file (T1000.bin). Using the TFTP
protocol, the latest versions of these files can be loaded onto a Tasman Networks router from
any accessible TFTP server.
A software upgrade consists of two files: T1000.Z and T1000.bin. The .Z file is the operating
system for the Tasman Networks system; the .bin file contains the downloadable boot images.
NOTE: Tasman Networks systems do not support two simultaneous downloads.
Refer to the appropriate Command Reference Guide (domestic or international products) for
NOTE:
specific command parameters, options, and context.
If you must issue the file download command, do so only when the source of the download file
is currently answering a ping command and there is no immediate concern about unscheduled
power outages. This situation is a cause for concern because a problem can arise when there is
insufficient Flash space to hold a backup copy of the downloaded T1000.Z file. When this
occurs, the system prompts for approval to continue. However, if power fails or there are
network problems during the file download, the system may not be able to boot from flash
because the file may be incomplete or corrupt. If this occurs, you can boot using FTP. Refer to
Booting From a Network TFTP Server on page 49 for this procedure.
