Introduction
LB9217A: 17-Port Modular Fast Ethernet Switch
The 17-Port Switch is a modular switch consisting of three expansion slots: two
for 8-port 10/100BaseTX/FX module, and one for 1-port 100BaseFX module. This
allows the switch to provide up to 17 ports when all the three slots are fit with
modules.
Cost-Effective Migration
The 17-Port Switch is capable of integrating legacy 10Mbps networks with
100Mbps Fast Ethernet networks. In addition, the 17-Port Switch provides an
easy and affordable solution for migrating from copper cabling to fiber
connection when it is equipped with suitable modules to provide both TX and FX
ports.
Flexibility through Modules
Seeing fiber connection become popular while the fiber cabling in small business
environment is still not widespread, the 17-Port Switch is designed to deliver
flexibility through a wide variety of TX and FX modules. Most of the modules
combine TX and FX ports to provide more customization options.
<NOTE> Desired module shall be ordered separately.
Fiber-Connectivity
As a Fast Ethernet switch, the 17-Port Switch is specifically designed to meet the
demanding need for fiber. The switch provides up to 17 ports for 100BaseFX,
multi-mode or single-mode fiber. For multi-mode fiber port, it allows SC, ST,
MT-RJ, VF-45 or LC connector. For single-mode fiber port, it allows SC
connector only. The fiber ports allow maximum segment distance of 75 km when
using single-mode fiber, and therefore, the 17-Port Fiber Switch is an optimum
solution for long distance connection.
Basic Configuration Features
The 17-Port Switch supports port-based Virtual Local Area Networking (VLAN)
and MAC-based trunking technologies. Such advanced features bring network
administrators a powerful yet easy-to-use tool to reduce unnecessary traffic,
efficiently segment the network, and enhance network security.
Standards Compliant
The 17-Port Switch fully complies with IEEE802.3 10BaseT as well as
IEEE802.3u 100BaseTX/FX standards.

Switch Configuration
This section explains the configuration of VLAN and trunking settings.
Setting up Console Port Connection
To configure your switch through the console port, it is necessary to first
configure a terminal emulation program. The HyperTerminal for Windows 95, 98,
and NT is suggested.
yFirst, check the switch, cables, and computers for proper installation before
configuration.
yConnect a PC or any VT100 compatible terminal to the console port on the
back of the unit using one RS232 serial cable. Turn on both end devices.
yConfigure the baud rate and character format of the terminal or PC to match
the default settings shown below.
Console Port Default Settings
Terminal type VT100
Port type (COM 1~4)
Communication Mode 8 data bits, 1 stop bit, no parity baud rate of 9600bps
(for initial configuration)
Flow Control Yes
Hardware Compression N/A

Main Menu
This main menu shows you the default configuration of the switch.
By default, all TX ports are set at auto-negotiation and flow control on, all FX
ports are set at 100Mbps with full duplex and flow control off, and all ports are
grouped into V1 (VLAN group 1).
These are the valid commands; capitalization is not required:
[W] Move the cursor up
[S] Move the cursor down
[A] Move the cursor to the left
[D] Move the cursor to the right
[R] Default
[V] Routing
[SPACE] Option
[ENTER] Apply and save the setting
[ESC] Abort

Port Settings
The duplex mode and speed can be altered and the flow control can be turned
on/off to accommodate special needs.
Follow these steps to change the speed/duplex mode setting or to toggle flow
control ON/OFF:
yMove the cursor to MODE column to change the speed/duplex mode setting, or
move the cursor to FLW column to change the flow control setting
yMove the cursor and select a port
yPress [SPACE] and select a desired setting from the list that appears on the
screen
yPress [ENTER] to apply and save the setting
FX Ports
The port setting for the fiber module is slightly different from the TX port.
Consult the following table for a brief description on FX ports:

Port-based VLAN & Settings
The 17-Port Switch allows up to sixteen port-based VLAN domains. Assign each
port to a VLAN group or a couple of VLAN groups according to accessibility
needs.
The VLAN setting: follow these steps to assign VLAN groups.
yMove the cursor to VLAN1 ~ 16 column
yMove the cursor and select a port
yPress [SPACE] and show Vto the desired port
yPress [ENTER] to apply and save the setting
For example, here we have the port 17 assigned as routing (uplink) port. The port
1 ~ port 16 are divided into five different VLAN groups (VLAN 1, 2, 3, 4, and 5).
VLAN 1: port 1, 2, 3
VLAN 2: port 4, 5, 6
VLAN 3: port 7, 8, 9
VLAN 4: port 10, 11, 12
VLAN 5: port 13, 14, 15, 16, 17
For example, the port 1, 2, and 3 (VLAN 1) can not communicate with the port 4,
5, and 6 (VLAN 2).
The routing (uplink) port setting: follow these steps to have an assigned
routing (uplink) port. Then separate the rest each port to a different VLAN group.
The rest each port can only uplink through the assigned routing (uplink) port and
can’t communicate with each other.
yEnter [V] from the Main Menu
yMove the cursor to a desired routing (uplink) port
yPress [SPACE] and show Vto the desired routing (uplink) port

Max Express Ethernet Switch LB9217A-R2 & Applicable Modules
18
yPress [ENTER] to apply and save the setting, then all the other ports will be
assigned to each different VLAN group and use the desired port as the routing
(uplink) port
For example, here we have the port 17 assigned as routing (uplink) port. The port
1 ~ port 16 are divided into each different VLAN groups. And the user on the
port 1 ~ port 16 can uplink through the port 17 only and can not communicate
with each other.
MAC-based Trunking & Settings
Trunking is also called link aggregation, which serves as a shortcut to increase
the bandwidth on your network. Trunking is a method of physically linking
together several ports to act as a single port with higher bandwidth. This
functionality allows scaling of bandwidth.
The 17-Port Switch supports trunking of up to 4 ports, either 2-port or 4-port.
For a 100BaseTX/FX network, you will gain 400Mbps bandwidth when you trunk
two ports, each of 200Mbps. The more ports you trunk, the more bandwidth you
gain.
Follow these steps to configure the 2-port trunking.
yMove the cursor to TRUNK column
yMove the cursor and select port 1
yPress [SPACE] and show Tto port1 and port2
yPress [ENTER] to apply and save the setting

Max Express Ethernet Switch LB9217A-R2 & Applicable Modules
19
<NOTE> Can only choose port1 and port2 for 2-port trunking
Follow these steps to configure the 4-port trunking.
yMove the cursor to TRUNK column
yMove the cursor and select port 1
yPress [SPACE] and show Tto port1 and port2
yMove the cursor and select port 3
yPress [SPACE] and show Tto port3 and port4
yPress [ENTER] to apply and save the setting
<NOTE> The trunking ports will be disabled for VLAN group settings.

Installation
This chapter gives step-by-step installation instructions for the 17-Port Switch.
Selecting a Site for the Switch
As with any electric device, you should place the switch where it will not be
subjected to extreme temperatures, humidity, or electromagnetic interference.
Specifically, the site you select should meet the following requirements:
- The ambient temperature should be between 32 and 104 degrees Fahrenheit (0
to 40 degrees Celsius).
- The relative humidity should be less than 90 percent, non-condensing.
- Surrounding electrical devices should not exceed the electromagnetic field
(RFC) standards for IEC 801-3, Level 2 (3V/M) field strength.
- Make sure that the switch receives adequate ventilation. Do not block the
ventilation holes on each side of the switch or the fan exhaust port on the
rear of the switch.
- The power outlet should be within 1.8 meters of the switch.
Connecting to Power
yConnect the supplied AC power cord to the receptacle on the back of the
switch, and then plug it into a standard AC outlet with a voltage range from
100 to 240 Vac.
