3 Quick Start Guide

This section provides the basic instructions to set up the GigaX environment.
Refer also to the GigaX Series Installation Guide.

Part 1 shows you how to install the GigaX on a flat surface or on a rack.

Part 2 provides instructions to set up the hardware.

Part 3 shows you how to configure basic settings on the GigaX.

Obtain the following information from your network administrator before proceeding:

IP address for the switch

Default gateway for the network

Network mask for this network

3.1 Part 1 — Installing the hardware

3.1.1 Installing the switch on a flat surface

The switch should be installed on a level surface that can support the weight
of the switches and their accessories. Attach four rubber pads on the marked
location on the bottom of the switch.

3.1.2 Mounting the switch on a rack

Attach brackets to each side of the switch and make the posts insert to the switch.

Insert and tighten two screws to securely attach the bracket to the rack on each side.

3.2 Part 2 — Setting up the switch

Connect the device to the power outlet, and your computer or network. See Figure 5.

3.2.1 Connect the console port

For console management, use an RS-232 (DB9) or a USB cable to connect the
switch. If you want to use WEB interface, connect your PC to the switch using
the Ethernet cable.

3.2.2 Connect to the computers or a LAN

You can use Ethernet cable to connect computers directly to the switch ports.
You can also connect hubs/switches to the switch ports by Ethernet cables.
You can use either the crossover or straight-through Ethernet cable to connect
computers, hubs, or switches.

Use a twisted-pair Category 5 Ethernet cable to connect the
1000BASE-T port. Otherwise, the link speed can not reach
1Gbps.

3.2.3 Attach the RPS module

Connect your RPS module to the RPS jack and make sure the other end of the
RPS is connected to the power cord. Connect to the power cord to a grounded
power outlet.

3.2.4 Attach the power adapter

Connect the AC power cord to the POWER receptacle on the back of the switch
and plug the other end of the power cord into a wall outlet or a power strip.

Check the front LED indicators with the description in Table 4. If the LEDs light
up as described, the switch hardware is working properly.

installed an RPS module.

3.3 Part 3 — Basic switch setting for management

After completing the hardware connections, configure the basic settings for your
switch. You can manage the switch using the following methods:

• Web interface: the switch has a set of pages to allow to you manage it using
Java®-enabled IE6.0 or higher version.

• Command Line Interface: use console port to manage the switch.

3.3.1 Setting up through the console port

Use the supplied crossover RS-232 cable to connect to the console port on the
front right corner of the switch. This port is a male DB-9 connector, implemented
as a data terminal equipment (DTE) connection. Tighten the retaining screws on
the cable to secure it on the connector. Connect the other end of the cable to a
PC running terminal emulation software. e.g Hyper Terminal.

Use the supplied USB cable to connect to a PC. You have to install the USB
driver from the switch CD-ROM before the USB can work properly. The USB
drivers will simulate an additional COM port under Windows Me/2K/XP OS.

Make sure the settings of your terminal emulation software as follows:

Choose the appropriate serial port number

Set the data baud rate to 9600

Set the data format to no parity, 8 data bits and 1 stop bit

No flow control

Set VT100 for emulation mode

After setting up the terminal, you can see the prompt “ASUS login:” on the terminal.

10

GigaX3112 Series Layer 3 Managed Switch

Note

The default user name is “admin” without password.

You can change the password at any time through CLI (see
section 5.31). To protect your switch from unauthorized access,
you must change the default password as soon as possible.

Follow these steps to assign an IP address to the switch:

Type “enable”.

Type “configure terminal”, new prompt is “ASUS(config)#”.

Type “interface vlan 1”, the prompt is “ASUS (config-if)#”.

Type “ip address <your ip address> <your network mask>”. For example, if
your switch IP is 192.168.1.1 and the network mask is 255.255.255.0. Then
you should type “ip address 192.168.1.1/24”.

Type “end”, it will return to previous level with prompt “ASUS#”.

Type “write memory”, the changes will be applied and written to
configuration file.

Type “reboot”.

If the switch has to be managed across networks, then a default gateway or a
static route entry is required. Follow these steps to assign a default gateway or
static route entry to the switch:

Entering “ASUS#”.

Type “show running-configuration” to view current configuration. If
incorrect route entry has been set, you should type “no ip route

0.0.0.0/0 192.168.1.254” to remove it.

Type “configure terminal”, new prompt is “ASUS(config)#”.

Type “no ip route 0.0.0.0/0 192.168.1.254” to clear default route.

Type “ip route 0.0.0.0/0 192.168.1.2” to set your default route.

Type “end”

Type “write memory”.

Note

3.3.2 Setting up through the web interface

To successfully connect your PC to the switch, your PC must have a valid IP
in your network. Contact your network administrator to obtain a valid IP for the
switch. If you wish to change the default IP address of the switch, follow section

3.3.1 to change the IP address.

If Ja va Runtime Environment is not i nst all ed on your PC, Your PC will
automatically downloads and installs it. It means that your PC should be able
to reach the web site. If the Internet is not available, you should prepare it on
diskette and install it.

From any PC connected to the network that the switch can access, open your
Web browser (Internet Explorer), and type the following URL in the address/
location box, and press <Enter>:

http://192.168.1.1

This is the factory default IP address of the switch.

A login screen appears, as shown in Figure 6.

Figure 6. Login screen

Enter your user name and password, and then click to enter the Configuration
Manager. Use the following defaults the first time you log into this interface:

Default User Name: admin
Default Password: <none>

You can change the password at any time (see section 6.3.1).

The browser will download java applet from the switch and it will
take a little time.

12

GigaX3112 Series Layer 3 Managed Switch

Note

To setup a new IP address, click “System”, select IP Setup. Fill in the IP address,
network mask and default gateway, then click OK.

If your new address is different from the default, the browser wonʼt be able to
update the switch status window or retrieve any page. This is normal. You have
to retype the new IP address in the address/location box, and press <Enter>.
The WEB link returns.

A login window appears immediately after you click OK. See the figures on the
next page.

Note that the GigaX 3112 and GigaX 3112F models have the
same web interface, except for the front panel image on top of
the screen (see figures on the next page).

The following sections show only Gx3112F image as example to
configure both GigaX3112 and GigaX3112F model.

4 Management with the web interface

The switch provides Web pages that allow switch management through the
Internet. The program is designed to work best with Microsoft Internet Explorer®

6.0, or later versions.

4.1 Log into web user interface

From a PC, open your web browser, type the following in the web address (or
location) box, and press <Enter>:

http://192.168.1.1

This is the factory default IP address for the switch. A login screen displays,
as shown in Figure 8.

Figure 8. Configuration manager login screen

Enter your user name and password, then click OK.

Use the following defaults the first time you log into the program. You can
change the password at any time through CLI interface (see section 6.3.1).
