2.3. Preparing for Configuration

To configure a SMC2585W-G, a managing computer with a Web browser is needed. For
first-time configuration of a SMC2585W-G, an Ethernet network interface card (NIC) should
have been installed in the managing computer. For maintenance-configuration of a deployed
SMC2585W-G, either a wireless computer or a wired computer can be employed as the
managing computer.

NOTE: If you are using the browser, Opera, to configure an SMC2585W-G, click the menu

item File, click Preferences... click File types, and edit the MIME type, text/html, to add a
file extension “.sht” so that Opera can work properly with the Web management pages of the
SMC2585W-G.

Since the configuration/management protocol is HTTP-based, you have to make sure that

the IP address of the managing computer and the IP address of the managed
SMC2585W-G are in the same IP subnet (Default IP address is set to DHCP client, it will

default to 192.168.2.50 if there is no DHCP server present.)

2.3.1. Connecting the Managing Computer and the

SMC2585W-G

To connect the managing computer and the SMC2585W-G for first-time configuration, you
have two choices as illustrated in Fig. 4.

You can use either a cross-over Ethernet cable (included in the package) or a switch/hub
with 2 straight-through Ethernet cables.

NOTE: One connector of the Ethernet cable must be plugged into the LAN Ethernet port of

the SMC2585W-G for configuration.

2.3.2. Changing the TCP/IP Settings of the Managing

Computer

Use the Windows Network Control Panel Applet to change the TCP/IP settings of the
managing computer, so that the IP address of the computer and the IP address of the
SMC2585W-G are in the same IP subnet. Set the IP address of the computer to

192.168.2.xxx (Default IP address is set to DHCP client, it will default to 192.168.2.50 if

there is no DHCP server present.)

TIP: You can use SMC2585W-G Scan Utility on the CD-ROM to scan for all the

SMC2585W-Gs on the network. Double-click a scanned SMC2585W-G to launch the Web
browser to manage the SMC2585W-G. Note that this utility does not discover the
SMC2682W.

NOTE: On Windows 2000/XP, SMC2585W-G Scan Utility can only be run by a user with

administrator privilege.

NOTE: For some versions of Windows, the computer needs to be restarted for the changes

of TCP/IP settings to take effect.

2.4. Configuring the SMC2585W-G

The SMC2585W-G is DHCP client enabled by default. After the IP addressing is configured,
launch a Web browser on the managing computer. Then, go to “http://192.168.2.50” to log
on to the SMC2585W-G for Web-based management.
