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
Connect the device to the power outlet, and your computer or network.
Figure 4 illustrates the hardware connections.
3.1.1 Installing the switch on a flat surface
The switchshould 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
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.

GigaX Series L2 Managed Switch User’s Guide
3.2 Part 2 — Setting up the switch
Connect the device to the power outlet, and your computer or network. See
Figure 4.
3.2.1 Connect the console port
For console management, use an RS232 (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
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 back 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. 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.
