Connecting the PRP to an Ethernet Network
Figure 3-15 RJ-45 Receptacle and Plug (Horizontal Orientation)
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 cable pinouts shown in
Figure 3-16 or Figure 3-17 .
