Downloading a File
This procedure explains how to download a file from a TFTP server on
your network to the switch using the web browser interface. You can
download any of the following files:
ˆ AT-S63 image file
ˆ Boot configuration file
ˆ CA certificate
Here are the general guidelines to follow when performing this procedure:
ˆ You must use TFTP to download a file from a web browser
management session.
ˆ There must be a node on your network with the TFTP server software.
ˆ The file must be stored on the TFTP server node.
ˆ You should start the TFTP server before you begin the download
procedure.
ˆ The switch must have a routing interface on the local subnet from
where it will reach the TFTP server. The switch uses the IP address of
the interface as its source address when sending packets to the TFTP
server. This rule applies to both master and slave switches in an
enhanced stack. For a switch without a routing interface, you can
download the file from a local management session on the switch
using Xmodem or, alternatively, switch to switch.
ˆ You cannot download a private encryption key onto a switch, but you
can a public key. However, since the switch can use only those
encryption keys it has generated itself, Allied Telesis recommends
against downloading any keys onto the switch.
ˆ The web browser interface does not support downloading a file to a
compact flash memory card in a switch.
If you are downloading the AT-S63 image file, note these additional
guidelines:
ˆ The AT-S63 image file contains the bootloader for the switch. You
cannot load the image file and bootloader separately.
ˆ Installing a new AT-S63 software image does not change the current
configuration of a switch.
ˆ If you are upgrading the AT-9400 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
interface is assigned the same address. If the unit obtained its IP
configuration from a DHCP or BOOTP server, the interface is created
