General Description
This command is used to download new versions of the AT-S85 and
AT-S97 boot loaders and management software to the management and
media converter modules in a chassis from a TFTP server. Allied Telesis
may post new versions of these files on our web site so our customers can
update their equipment with the latest files.
You can also use this command to download master configuration files
that you edited at your management workstation to the management
module.
To download a bootloader or image file onto all of the media converter
modules in a system, use the FILE FASTDOWNLOAD command. See
“FILE FASTDOWNLOAD” on page 186.
Description of Syntax 1
This command is used to download new versions of the boot loader files to
the management modules and the media converter modules from a TFTP
server. The boot loader is part of the operating system of a module.
There are different boot loaders for the different types of modules. The
AT-MCF2000M Management Module uses the AT-S97 boot loader and
the media converter modules the AT-S85 boot loader. The boot loader
files are identified by their “.BIN” filename extension and the “S85” and
“S97” in the filenames.
A boot loader must be stored on a module in an area of memory referred
to as BOOTBLOCK. This section of memory is separate from the file
system and it cannot be displayed with the FILE SHOW command. When
you enter the FILE DOWNLOAD command, you must specify
BOOTBLOCK as the destination. If you specify a filename as the
destination, the command stores the file in the file system of the module.
This is an inappropriate destination for a boot loader. (If you do
inadvertently download a boot loader file into the file system of a module,
you can delete it with the FILE DELETE command. For instructions, refer
to “FILE DELETE” on page 176.)
After receiving a new boot loader, a module tests the file before writing it to
the BOOTBLOCK area of flash memory to determine whether the file is
appropriate for its module type. If the file type is correct, it writes the file to
the BOOTAPP section. If it is not, it discards the file. This protects the
module from installing the wrong boot loader.
This command has the following guidelines:
ˆ The filename extension of the source file must be “.BIN” and the
destination must be BOOTBLOCK.
ˆ When upgrading both the boot loader and the management software
on the modules, you should download the new boot loader file first.
