Downloading the AT-S63 Image File onto a Switch
This section contains the following two procedures:
ˆ “Downloading the AT-S63 Image from a Local Management Session”
on page 224
ˆ “Downloading the AT-S63 Image from a Remote Management
Session” on page 228
These procedures explain how to download a new version of the AT-S63
image file onto a switch from a local management session using either
Xmodem or TFTP, or from a remote management session (i.e, Telnet or
SSH) using TFTP. If you have several switches in an enhanced stack to
upgrade, you can simplify the procedure by updating the master switch
first by performing one of the procedures in this section and then
instructing the master switch to upload its image file to the other switches,
as explained in “Uploading the AT-S63 Image File Switch to Switch” on
page 230.
Caution
The switch stops forwarding Ethernet traffic after it has downloaded
the image file and begun to initialize the software. Some network
traffic may be lost.
Guidelines
The following guidelines apply to both Xmodem and TFTP downloads:
ˆ These procedures download a new AT-S63 image file into the
application block portion of the switch’s flash memory. The application
block is the area of flash memory reserved for the active AT-S63
image file on a switch and is separate from the file system.
ˆ Alternatively, you can download the image file into the switch’s file
system and later copy it into the application block using the LOAD
command in the command line interface. To download an image file
into the file system rather than the application block, refer to
“Downloading a System File” on page 236.
ˆ All models of the AT-9400 Series use the same AT-S63 management
software image.
ˆ The current configuration of a switch is retained when a new AT-S63
software image is installed. To return a switch to its default
configuration values, refer to “Returning the AT-S63 Management
Software to the Factory Default Values” on page 78.
ˆ If you are upgrading an AT-9400 Series switch from AT-S63 version
1.3.0 or earlier and the switch has an IP address, the upgrade process
automatically creates a routing interface on the switch to preserve the
device’s IP configuration. If the switch has a static address, the
