Introduction
The software in Allied Telesis routers and managed Layer 3 switches
is constantly upgraded to improve networking functionality. At times,
issues are identified in the software, customers request
enhancements, and new technologies are integrated into the device.
What information is in this document?
This document has the following sections:
• "Background information on software versions" on page 2
• "How to upgrade the software" on page 5, which consists of:
• "How to load the files onto the device" on page 5
• "How to enable the software and its licence" on page 9
• "How to install software versions" on page 11
• "Software for managing upgrades" on page 12
Full details for the commands to download and install software
versions are in the “Managing Configuration Files and Software
Versions” chapter of the Software Reference for your device.
Finding the features in a software version
Every software version comes out with a release note, which are
available on the Allied Telesis website at the same place as release
files. There are two kinds of release notes, depending on whether the
version is an initial version or a maintenance version:
• initial version—these versions generally have many new features
and enhancements, which the release note describes.
• maintenance version—these versions contain resolutions to issues
and may contain enhancements, which the release note describes.
If you are upgrading from a maintenance version of one software
version to a maintenance version of another, you need to read the
release note for both the initial release and the maintenance release.
For example, when upgrading from 276-03 to 281-04, read the note
for 2.8.1 and for 281-04.

Upgrade Release Software on Allied Telesis Routers and Managed Layer 3 Switches 2
Background information on software versions
Software versions contain the code that enables your router or switch to run, and can be
downloaded from the Allied Telesis website to upgrade your device. Version files are several
megabytes in size, depending on platform and software version.
Types of software version
Different product series store the firmware in different types of files, as the following table
shows.
The following sections give more information about each of these file types.
Caution: A software version is specific to a particular router or switch series. It is not possible
to run a release on any router or switch series other than that for which the release was made.
The same router or switch release may, however, run on several models in the same series (see
"Release file product series abbreviations" on page 3). If you try to load the wrong software
release into a device the boot process will fail.
Base package files
On AT9900s and x900-24X Series, a base package file contains the software that runs the switch
and controls features.
Naming convention
Base packages use the following naming convention:
Files are named 9924Ts_yyy-zz.pkg, where:
• 9924Ts indicates that the product series is AT-9900s or x900-24X
• yyy is the version number, such as 311 for 3.1.1
• zz is the maintenance version number, such as 03 for the third maintenance version. If zz is 00,
this is the initial release of that software version.
Maintenance version files are complete packages—these switches do not use a “patch” system.
Product File type File extension Example
AT9900s and x900-24X Series base package .pkg 9924Ts_311-03.pkg
Other routers and switches release .rez 54-281.rez
54281-04.rez
