3 Quick start guide

This section provides the basic instructions to set up the switch environment.
Refer also to the GigaX2024/2048 Installation Guide.

Part 1 shows how to install the GigaX2024/2048 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 GigaX2024/2048 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 rack­mount 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.

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

the switch features a set of web pages which enable easy

using console port to configure the switch.

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 115200 (or 9600 on some models)

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.

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

6. 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

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

network gateway IP> 0.0.0.0 1

net interface ip sw0 192.168.10.1

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

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

(see figures on the next page).

The following sections show only one screen image (that of the
GigaX 2048 model) if the screen contents for both models are
the same. Both the GigaX 2048 and 2024 screens are shown
