PRP Ethernet Connections
Figure 3-15 shows 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 3-7
lists 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.
