5Router Software Maintenance

Introduction	The Router manages three types of files:
	■ Boot ROM image file used for booting the application at boot
	■	Application image file (main software)
	■	Configuration file

Software maintenance mainly involves these three types of files, including:

■Upgrading application and Boot ROM image through XMODEM

■Upgrading the application image through TFTP

■Uploading/downloading the application image and configuration file through FTP

The Router 5000 are loaded initially. You may need to upgrade it and its corresponding Boot ROM image to accommodate new product features.

Examine the current version of the application and Boot ROM program before software upgrade. For the association between the version and Boot ROM image, see the corresponding Release Notes.
