Warning The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety
extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits. Because the BRI circuits are treated like
telephone-network voltage, avoid connecting the SELV circuit to the telephone
network voltage (TNV) circuits.
