PRP Port Connection Guidelines
This section contains detailed cabling and signal information for all interface and
port connections to the PRP. It also provides information for Ethernet routing and
equipment.
Caution 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.
PRP Auxiliary and Console Port Connections
The PRP has two RJ-45 connection ports:
• Auxiliary port— DTE RJ-45 interface for connecting a modem or other DCE
device (such as a CSU/DSU or another router) to the PRP.
• Console port—DCE RJ-45 interface for connecting a data terminal device to
the router, which you need to perform the initial configuration of the router.
Note The auxiliary and console ports are asynchronous serial ports. Ensure that
devices connected to these ports are capable of asynchronous
transmission.
