Upgrading AT-S25 Version 1.5.6.2 or Earlier to Version 2.0.2
or Later
This section contains the procedures for upgrading an image file to
AT-S25 Version 2.0.2 or later.
Caution
The configuration file in the AT-S25 Version 1.5.6.2 or earlier version
is not compatible with the AT-S25 Version 2.0.2 or later versions of
code; therefore, the user needs to save the configuration settings
such as the static MAC addresses, VLAN settings, port configuration
settings, etc. before downloading the latest version of code. Once
the latest version of code is downloaded, these settings must be
reconfigured manually.
Note
You cannot perform this procedure from a Telnet or Web Browser
management interface.
Note
The switch will not forward Ethernet traffic during the software
download and initialization process.
Two methods that you could use to download the image file are the
TFTP and XModem methods.
❑ TFTP Method: This method is used to upgrade the software to the
switch modules that are part of a stacked configuration or to the
entire stack at once. This method may be performed from either a
local or a remote host PC.
❑ XModem Method: This method is used to upgrade the software to
an individual switch module of a stack or to a stand-alone switch
module. If the switch module is a member of a stack, the stacking
cable(s) must be disconnected from the module before starting
this procedure. This method may be performed from a local host
PC only.
Note
For faster transfer, the TFTP method is preferable.
For guidelines or background information on how to upgrade the
software using TFTP, refer to TFTP Guidelines on page 18.
