Switch software overview
Switch software includes the Boot ROM program and the system boot file. After powered on, the device
runs the Boot ROM program, initializes the hardware, and displays the hardware information. Then the
device runs the boot file. The boot file provides drivers and adaption for hardware, and implements
service features. The Boot ROM program and system boot file are required for the startup and running of
a device.
