Software upgrade configuration

Device software overview

The device software comprises the Boot ROM and the system software images. After the device is
powered on, it runs the Boot ROM image, initializes hardware, and displays the hardware information.

implements service features. The Boot ROM and system software images are required to start up and run
the device. Figure 40
