Downloading a New AT-S62 Image File onto a Switch
The procedures in this section explain how to download a new AT-S62
image file onto the switch. These procedures can be used to update the
AT-S62 image file on a switch with a new version of the file. If you have
an enhanced stack of AT-8500 Series switches, the easiest way to update
the switches is to first update the master switch 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 an
AT-S62 Image File Switch to Switch on page 183.
There are two ways that you can download a new image file onto a
switch. You can do it from a local management session using either
Xmodem or TFTP, or from a remote Telnet management session using
TFTP, exclusively. Each method is described in a separate section in this
section. The procedures are:
❑ Downloading an AT-S62 Image from a Local Management Session
on page 177
❑ Downloading an AT-S62 Image from a Telnet Management
Session on page 181
Caution
Installing a new AT-S62 image file will reset the switch. Some
network traffic may be lost.
Guidelines
The following guidelines apply to both Xmodem and TFTP downloads:
❑ The following procedures download a new AT-S62 image file into
the application block portion of the switch’s flash memory. The
application block is the area of memory reserved for the active
AT-S62 image file on a switch and is separate from the file system.
Alternatively, you can download the image file into the switch’s
file system and then later copy it into the application block. The
drawback to this approach is that the image file will require nearly
all 2 megabytes of the file system, leaving almost no room for
other files, such as configuration files and SSL certificates. To
download an image file into the file system rather than the
application block, refer to Downloading a System File on page
188.
❑ All models of the AT-8500 Series switches use the same AT-S62
management software image.
❑ The current configuration of a switch is retained when a new
AT-S62 software image is installed. If you want to return a switch
