Chassis Switch provides two ways for switch upgrade: Boot ROM upgrade and the TFTP/FTP upgrade under
Shell.

4.5.1 Chassis Switch System Files

The system files includes system image file and boot file. The updating of the Chassis Switch is to update the
two files by overwrite the old files with the new ones.
The system image files refers to the compressed files of the Chassis Switch hardware drivers, and soft ware
support program, etc, namely what we usually call the IMG updat e file. The IMG file can only be saved in the
FLASH with a defined name of nos.img
The boot file is for initiating the Chassis Switch, namely what we usually call the ROM update file (It can be
compressed into IMG file if it is of large size). The boot file can only be saved in the ROM in which the file
name is defined as boot.rom
The update method of the system image file and the boot file is the same. The Chassis Switch supplies the
user with t wo modes of updating: 1. BootROM mode; 2. TFTP and FTP update at Shell mode. This two
update method will be explained in details in following t wo sections.
