3 Quick start guide

This section provides the basic instructions to set up the switch environment. Refer also to the GigaX2024B Installation Guide.

Part 1 shows how to install the GigaX2024B on a ﬂat surface or on a rack.

Part 2 provides instructions to set up the hardware.

Part 3 shows how to conﬁgure basic settings on the GigaX2024B switch.

Before start, obtain the following information from your network administrator:

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 must be installed on a level surface that can support the weight of the switch and its accessories. Attach four rubber pads on the marked location on the bottom of the switch.

3.1.2 Mounting the switch on a rack

1. Position the bracket posts with the holes on both sides of the switch.

2. Use three screws to secure the bracket to the switch.

3. Repeat the above steps for the other side of the switch.

4. Use four rack-mount screws to mount the switch to the rack (The rack-mount screws are not provided in the package).

3.2 Part 2 — Setting up the switch

3.2.1 Connect the console port

For console management, use an RS232 (DB9) or a USB cable (requiring installation of the USB driver included in the support CD) to connect the switch. If you want to use Web interface, connect your PC to the switch using an Ethernet cable.

GigaX2024B L2 Managed Switch User Manual

3.2.2 Connect to the computers or a LAN

You can use Ethernet cable to connect computers, hubs and other switches to the switch ports. Either crossover or straight-through Ethernet cable can apply for connecting these devices.

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 Redundant Power Supply (RPS) module (optional) to the RPS jack on the rear panel of the switch 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

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:

management via Java®-enabled IE5.0 or higher version.

•

Command Line Interface:

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 back 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.

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

3. 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

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

the switch features a set of web pages which enable easy

using console port to conﬁgure the switch.

5. Type “login” to access the command line interface. The default user name is “admin”. Skip the password by pressing

GigaX2024B L2 Managed Switch User Manual

<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.

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

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

a) Type “enable”.

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

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

d) 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”.

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

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

g) 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:

a) Entering “ASUS#”.

b) Type “ show run ning -con figu rati on” to vie w cur rent con figu rati on. 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.

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

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

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

f) Type “end”

g) Type “write”.

3.3.2 Setting up through the Web interface

To 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.

1. If Java Runtime Environment is not installed on your PC, Your PC will automatically download 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.

Java Runtime Environment is necessary to install on you PC to access Web configuration manager. You can install it from support CD packed with the main device.

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

This is the factory default IP address of the switch.

A login screen appears, as shown in Figure 6.

<Enter>

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

The browser will download java applet from the switch and this will take several seconds.

3. To setup a new IP address, click address, network mask and default gateway, then click OK.

4. When the new address is applied to the switch, the browser can no longer update the switch status window or retrieve any page. You need to retype the new IP address in the address/location box, and press Web link returns.

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 with Java® enabled.

4.1 Log into Web user interface

1. Open the web browser (IE) on your computer, type the following in the web address (or location) box, and press

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

2. Enter your user name and password, then click OK.

Use the following defaults the first time you log into the system. You can change the password at any time through CLI interface (see section 6.3.1 on page 57).

Default User Name: admin

Default Password: <no password>

The home page appears each time you log into the program. See Figures 11 and 12).
