Chapter 20: Download and Upload Commands

Description
This command can download a new version of the AT-S39 software
image file or switch configuration onto an AT-8000 Series switch. You
can use this command to download files as follows:
❑ From a local management session
❑ From a remote management session
❑ From a master switch to other switches in an enhanced stack
To download a file locally, you must start a local management session
directly on the switch. This entails connecting a terminal or PC with a
terminal emulator program to the RS232 Terminal Port on the switch, as
explained in the AT-S39 Management Software User’s Guide. You can
use either Xmodem, or if the switch has an IP address and subnet mask,
TFTP.
You can also download a file to a remote switch. This can be a switch
accessed through enhanced stacking or from a Telnet management
session. This type of download uses TFTP exclusively. For this type of
download, the switch must have an IP address and subnet mask.
The final method is switch-to-switch. Here, you instruct the master
switch of an enhanced stack to download its AT-S39 image file or
configuration file to other switches in the enhanced stack. This method
is useful if you have a large number of AT-8000 Series switches in your
network. You can download the AT-S39 software from the master switch
to the other switches in an enhanced stack so that all the switches are
using the same version of management software.
With a switch-to-switch download, you can also download the master
switch’s configuration file to other switches. This is useful in network
environments where there are a AT-8000 Series switches that need to be
configured the same, or nearly the same. You can configure the master
switch of an enhanced stack network, and then download its
configuration file to the other switches, saving you the trouble of having
to configure each switch individually.
Here are general guidelines that apply to all download methods:
❑ All switch models in the AT-8000 Series use the same AT-S39
software image.
❑ In networks consisting of several AT-8000 switches, you can
simplify an upgrade procedure by upgrading a master switch to
the latest software version via a local or Telnet management
session and then downloading the new software switch-to-switch
from the master switch to the slave switches.
