Using Primary and Secondary flash image options
The switches covered in this guide feature two flash memory locations for storing switch software image files:
With the Primary/Secondary flash option, you can test a new image in your system without having to replace a previously existing image. You can also use the image options for troubleshooting. For example, you can copy a problem image into Secondary flash for later analysis and place another, proven image in Primary flash to run your system. The switch can use only one image at a time.
The following tasks involve primary/secondary flash options:
Displaying the current flash image data and determining which switch software versions are available
Switch software downloads
Replacing and removing (erasing) a local switch software version
System booting
