# 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 1. 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 1/2 means block 1, switch 2.

Carefully check the requirements of your installation against the list below. The default settings suit most installations. The defaults are:
