AT-S25 Management Software Release Notes

Upgrading AT-S25 Version 1.5.6.2 or An Earlier Version to Version 2.0.2
This section contains the procedures for upgrading an image file to AT-S25 Version 2.0.2.
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; therefore, the user needs to save the
configuration settings such as the static MAC addresses, VLAN settings, port
configuration settings, etc. before downloading Version 2.0.2. Once Version 2.0.2 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 the following section: TFTP Guidelines.
