3.2.4 Managing Firmware
You can upload and download firmware to and from a TFTP server. By saving
runtime code to a file on a TFTP server, that file can later be downloaded to the
switch to restore operation. You can also set the switch to use new firmware without
overwriting the previous version.
When downloading software files, note the following points:
■ The destination file name should not contain slashes (\ or /).
■ The leading character of the file name should not be a period (.).
■ The maximum length for file names on the TFTP server is 127 characters.
■ The maximum length for file names on the switch is 32 characters.
■ Valid characters are A-Z, a-z, 0-9, “.”, “-”, and “_”.
■ Only two copies of the System Software file (containing the runtime firmware)
can be stored in the file directory on the switch. The currently designated startup
version of this file cannot be deleted. If there are two copies of the System
Software file present, you can delete the one that is not currently designated as
the startup version and replace it with a new file, or you can copy a new one into
the directory using one of the existing file names. Alternatively you can remove
the startup designation from the current startup file, delete that file, copy a new
version of the System Software file into the directory, and finally make the new
file the designated startup file.
3.2.4.1 Downloading Switch Firmware From a Server
When downloading runtime code, you can specify the destination file name to
overwrite the current image, or first download the file to a different file name and
then set the new file as the startup file.
