Installing the router
Step 2: Set up a computer to access the router
Unless your network administrator or reseller has already configured the router—in
which case you can skip ahead to
—you will need to change a few
settings that are specific to your network.
The easiest way to do this is to connect a computer to the router and use an Internet
browser to access the routers’s configuration pages, as described below.
CAUTION!
To avoid disrupting network traffic, do not connect the router to an existing
LAN until after you have completed steps
.
a
Make sure your computer is set to be a DHCP client. The router is by
default a DHCP server on the LAN side, so any computer initially connect-
ing to it must be set up as a DHCP client. In other words, the computer you
are attaching must be configured to obtain an IP address automatically
from the router.
The procedure for setting up a computer to obtain an IP address automati-
cally varies according to the computer’s operating system. Typically it is a
TCP/IP configuration option. Consult your operating system’s online help
or user manual for details.
b
Connect the computer to one of the router’s 10/100 Ethernet LAN ports as
shown in
.
Make sure the router is still powered on before con-
necting any cables.
The router’s Ethernet LAN ports auto-detect and auto-
negotiate, so either a straight- or crossover-Ethernet cable can be used.
Check for a green LAN STAT LED on the front panel to verify a good
cable connection before proceeding.
c
If you changed any settings in the computer, restart it to release and renew
the IP address.

Alternative connection method (advanced)
You also have the option of attaching a computer to the RS-232 port and setting up
the router using the command line interface (CLI). This is typically done only if it
would be problematic to set up a Dynamic Host Control Protocol (DHCP) client
computer, or for large-scale deployments in which scripts are used to configure
many routers quickly. Refer to the
User’s Guide
and
CLI Reference Guide
for more
information about the CLI.
