92 There are two additional hardware buttons/switch available in the frontpanel for
95 ## 1.Host selector switch (selector switch)
97 This host selector switch/selector switch has 4 gpio connected as input and
98 based on the gpio state values the host selector switch value is derived. The
99 possible switch values can vary from 0 to 10. The specific mapping between gpio
