Updating Software Images and
Configuration Files
This chapter describes how to copy and save configuration files and software image files.
This chapter contains the following information:
Overview
For easy software image management, all Foundry devices support the download and upload of software images
between the flash modules on the devices and a Trivial File Transfer Protocol (TFTP) server on the network.
Foundry devices have two flash memory modules:
• Primary flash – The default local storage device for image files and configuration files.
• Secondary flash – A second flash storage device. You can use the secondary flash to store redundant
images for additional booting reliability or to preserve one software image while testing another one.
