III. Connecting the console cable
When configuring the router through a console terminal, follow these steps to connect the
console cable:
Step 1: Select a console terminal. It can be a standard ASCII terminal with a RS232 serial
port, or more commonly, a PC.
Step 2: Power down the router and the console terminal; connect the RS232 serial port on
the console terminal to the console port on the router through the console cable.
Step 3: Verify the connection and power up the devices.
The console terminal shows the startup information of the router if the connection is correct.
For details see the chapter “Starting and Configuring the Router”.
3.8 Connecting the Router to a LAN
I. Ethernet interface
The RPU provides two 100BASE-TX FE interfaces. For their attributes, refer to the section
“RPU”.
The RPU2 provides three 10/100/1000 Mbps auto-sensing Ethernet interfaces that each
accommodate an RJ-45 connector and an SFP module respectively for electrical and optical
connections.
The RPU2 provides three 10/100/1000 Mbps Ethernet interfaces, where two are electrical and
one provides both fiber-optic and electrical connectors.
When both electrical and optical connections are available, you can use only one at a time. For
the available SFP options and the interface attributes, refer back to the section “RPU2” in the
chapter “Router Overview”.
II. Ethernet cable
1) Electrical Ethernet interface cable
Electrical Ethernet interfaces usually use category 5 twisted-pair cables, as shown in the
following figure.
