PRP Ethernet Connections

Figure 3-15shows a PRP RJ-45 receptacle and cable connector. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 3-7lists the signal-to-pin correspondence for the RJ-45 receptacle.

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.
