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.
Depending on your RJ-45 cabling requirements, use the connector pinouts shown
in
Figure 3-16 or Figure 3-17.
