3Com Router 3000 ADSL2+ Family Getting Started Guide
Connecting the Router to a Console Terminal
Console cable
The console cable has an RJ45 connector at one end and a DB9 (socket) connector at the other
end.

Connecting the console cable
Follow these steps to connect the router to a console terminal:
Step 1: Select a console terminal. The console terminal can be either a standard ASCII terminal
with an RS-232 serial interface or more commonly, a PC.
Step 2: Power off the router and the console terminal, and then connect the RS-232 serial port on
the console terminal to the console port on the router using the console cable. Verify the
connection and power on the router. In normal cases, the startup information is displayed
on the terminal screen.
Connecting the Router to LAN
The 10/100 Ethernet LAN interfaces on the Router 3000 support MDI/MDIX auto-sensing.
Therefore, you can connect your router to another device using either a straight-through or
crossover cable regardless of whether the two devices are the same type.
Caution:
In preparing network cables, shielded cables are preferred for the sake of electromagnetic
compatibility.
Verifying Installation
After you complete installation, verify that:
•
The proper power supply is used.
•
The grounding wire of the router is correctly connected.
•
The console cable and the power cord are correctly connected.
