3 Quick start guide

This section provides the basic instructions to set up the GigaX2008EX working
environment. Refer also to the GigaX2008EX Installation Guide.

Part 1 shows you how to install the GigaX2008EX 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 GigaX2008EX.

Obtain the following i nform ation from your netw ork admini strat or be fore
proceeding:

IP address for the switch

Default gateway for the network

Network mask for this network

3.1 Part 1 — Install the hardware

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

3.1.1 Install 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 Mount the switch on a rack

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

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

3.2 Part 2 — Set up the switch

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

3.2.1 Connect the console port

For console management, use an RS232 (DB9) to connect the switch. If you
want to use Web interface, connect your PC to the switch using the Ethernet
cable.

7

GigaX2008EX L2 Managed Switch User Manual

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 power adapter

1. 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.

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

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 IE5.0 or higher version.

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

3.3.1 Setting up through the console port

1. Use the supplied crossover RS-232 cable to connect to the console port on
the front panel of the switch. This port is a male DB-9 connector, implemented
as 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.

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

a) Choose the appropriate serial port number
b) Set the data baud rate to 9600
c) Set the data format to no parity, 8 data bits and 1 stop bit
d) No flow control
e) Set VT1000 for emulation mode

3. After setting up the terminal, you can see the prompt “(ASUS)%” on the
terminal.

4. Type “login” to access the command line interface. The default user name is

9

GigaX2008EX L2 Managed Switch User Manual

“admin”. Skip the password by pressing <Enter>.

You can change the password at any time through CLI (see
section 5.3.1). To protect your switch from unauthorized access,
you must change the default password as soon as possible.

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

a) Type “net interface ip sw0 <your ip address> <your network mask>”.

For example, if your switch IP is 192.168.10.1 and the network mask is

255.255.255.0. Then you should type “net interface ip sw0 192.168.10.1

255.255.255.0”.

b) If the switch has to be managed across networks, then a default gateway

or a static route entry is required. Type “net route static add 0.0.0.0 <your
network gateway IP> 0.0.0.0 1” as your default route entry, as shown in
Figure 5.

Figure 5. Login and IP setup screen

3.3.2 Setting up through the Web interface

To successfully connect your PC to the switch, your PC must 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.

1. It is not necessary to login Web interface at the first time to use Web interface
because the default configuration for Web access authentication is disabled.
To secure the system configuration, please enable the authentication function
at the

Administration

page under

System

category. Skip step 2 if the

authentication is disabled.

2. At 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>:

10

GigaX2008EX L2 Managed Switch User Manual

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

En t e r your user na m e and pa s sword, and th e n cli c k OK to ente r the
Configuration Manager. Use the following defaults the first time you log into this
interface:

Default User Name: admin

Default Password: (no password)

You can change the password at any time (see section 5.3.1
System Commands).

3. To setup a new IP address, click

System

, then

IP Setup

(see Figure 7). Fill

in the IP address, network mask and default gateway, then click OK.

4. If your new address is different from the default, the browser cannot 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.

5. To enable authentication for Web access, click

Administration

on the menu

list, then select

Enabled

to start the protection.

A login window appears immediately after you click OK.
