# The Ringnode's hardware switches

| Some text is printed on the reverse of the board to indicate the function of each of the eight switches in switch block 2. Each individual switch is identified by a pair of numbers. The first number indicates the switch block, and the second number identifies the particular switch within the switch block. For example, switch 2/1 means block 2, switch 1.
