You can download software upgrades from a switch to one or more
switches on the network, or download onto a switch via Trivial File
Transfer Protocol (TFTP) from a TFTP server.
The switches initially use a factory-configured default download
password, ATS20 to authorize software downloads. You do not need
to manually enter this password to download software successfully.
Note
This download password can be changed to prevent unauthorized
changes to the switch firmware.

The switch uses TFTP of the TCP/IP protocol suite to download
software to other switches whether or not your network uses TCP/IP.
TFTP is transparent to other devices on the network.
The switch can download software within the following conditions:
❑ The switches must be directly connected to the same
network cable or joined by switches or bridges and routers,
if the gateway addresses in both switches are properly
configured.
❑ All switches receiving the same software must use the same
download password (ATS20). See Configuring IP
Parameters on page 4-6).

If you have TFTP, you can use it to download an image file from the
switch with the upgraded software. When issuing the TFTP get or put
command, take note of the following variables:
Image file name. Get the latest from Allied Telesyn’s website at
www.alliedtelesyn.com.
IP address. This is the IP address of the switch that is the source
or destination of the file.
Download password. The default download password is
ATS20 in uppercase.
File type. The file type is octet or binary.
Note
TFTP platforms vary. Some have graphical user interfaces while other
platforms require you to type the commands.
