Downloading Files from a Remote Management Session
This section contains the procedure for downloading a new AT-S39
software image or configuration file onto a switch from a remote
session. The remote switch can be a switch accessed through enhanced
stacking (such as a slave switch) or a switch where you started a Telnet
management session.
Please note the following before you begin the procedure:
You must use TFTP to remotely download a file.
There must be a node on your network that contains the TFTP
server software. The AT-S39 image file or configuration file to
download must be stored on the server.
You should start the TFTP server before you begin the download
procedure.
The switch where you are downloading the file must have an IP
address and subnet mask. Consequently, you cannot use TFTP on
a slave switch of an enhanced stack unless the switch has an IP
address. Rather, you would need to perform the download from a
local management session using Xmodem or, alternatively,
switch-to-switch, as explained in Downloading Files Switch to
Switch on page 232.
If you are downloading a new AT-S39 software image, the switch’s
current configuration settings (for instance, IP address, port
security, and virtual LANs) are not changed.
If you are downloading a configuration file, the switch’s current
configuration settings are overwritten by the configuration
settings contained in the file.
A configuration file should only be downloaded onto a switch of
the same model from which the configuration file originated (for
example, AT-8024M to AT-8024M). It is not recommended that
you download a configuration file onto a switch of a different
model (for example, AT-8012M to AT-8024GB). Undesired switch
behavior may result.
A switch running AT-S39 Version 1.4 or earlier must first be
ungraded to Version 1.4.1 or 1.4.2 before you can install a new
AT-S39 image.
Caution
Downloading a new AT-S39 image file or configuration file will
cause a switch reset. Some network traffic may be lost.
