CHAPTER 2: Overview
2. Overview
2.1 Introduction
The Managed 16-Port 10/100/1000 Ethernet Switch with 2 SFP (Small Fiber Port) Dual Media meets all IEEE
802.3/802.3ab/802.3u/802.3x/802.1q Gigabit and Fast Ethernet specifications. It has 16 10/100/1000-Mbps
twisted-pair ports and 2 Gigabit twisted-pair/SFP fiber slots for fiber modules. Connect sixteen 10/100/1000
twisted-pair devices, fifteen 10/100/1000 twisted-pair and one fiber device, or fourteen 10/100/1000 twistedpair and two fiber devices to the switch. Manage the switch through an Ethernet port using Web-based
management. The network administrator can logon to the switch to monitor, configure, and control each port’s
activity.
Ports 15 and 16 autodetect two media types: 10/100/1000-Mbps twisted pair and 1000-Mbps Small Fiber Port
(SFP) fiber. An SFP fiber transceiver module is used for high-speed connection expansion. The 1000-Mbps SFP
fiber transceivers are Gigabit Ethernet ports that fully comply with all IEEE 802.3z and 1000BASE-SX/LX
standards. The switch is compatible with the following optional fiber modules.
• LC Multimode Fiber Module (LGB200C-MLC) works with 850-nm multimode fiberoptic cable that’s up to
960 feet (300 m) long
• LC Single-Mode Fiber Module (LGB200C-SLC10) works with 1310-nm single-mode fiberoptic cable that’s
up to 6.3 miles (10 km) long
• LC Single-Mode Fiber Module (LGB200C-SLC30) works with 1550-nm single-mode fiberoptic cable that’s
up to 18.9 miles (30 km) long
The switch features QoS (Quality of Service), VLAN, and trunking. QoS enables the switch to support the ToS
field of an IP header (equal DSCP low 3 bits) on Layer 3 of network framework and six kinds of special network
transmission events on Layer 4. With VLAN, the switch supports port-based VLAN and IEEE802.1Q Tag VLAN.
It also supports 16 active VLANs and VLAN ID 1–4094. Port trunking allows one or more links to be aggregated
together to form a Link Aggregation Group by the static setting.
2.2 Components

3. Installation
3.1 Hardware and Cable Installation
Before installing the switch, make sure you are wearing a grounding strap to avoid damage caused by
electrostatic discharge. Also, confirm that the power switch is off before you insert the power cord into the
power receptacle.
3.1.1 INSTALLING THE OPTIONAL MODULES
NOTE
If you are not installing modules in Ports 15–16, skip this section.
1. Verify that the SFP module is the right model and conforms to the chassis.
2. Slide the module into the slot as shown in Figure 3-1. Make sure that the module is properly seated against
the slot socket/connector.
Figure 3-1. Installing an optional SFP fiber transceiver in the switch.
3. Install the fiber optic cable (see Section 3.1.2) for network connection.
4. Repeat the above steps for the second module and slot, if needed.
5. Power on the switch.
10
CHAPTER 3: Installation
3.1.2 CONNECTING THE CABLE
The switch’s twisted-pair ports support MDI/MDI-X auto-crossover, so you can use either straight-through or
cross-pinned UTP cable.
Use Category 5 or 5e grade RJ-45 twisted-pair cable to connect up to sixteen network devices (such as
workstations or servers) to the switch’s UTP ports.
Use 850-µm multimode, 1310-µm single-mode, or 1550-µm single-mode fiberoptic cable to connect the fiber
module to the network.
3.1.3 POWERING ON THE SWITCH
The switch supports a 100–240-VAC, 50–60-Hz power supply. The power supply will automatically convert the
local AC power source to DC power. It doesn’t matter whether any devices are plugged into the switch or not
when you power on the switch (including modules). Once the power is on, all LEDs (except for the Power
LED) will light immediately and then turn off. The Power LED will remain on.
After resetting, the bootloader will load the firmware into memory. This takes approximately 30 seconds. After
that, all LEDs will flash once and the switch will automatically run a self-test.
3.1.4 INSTALLING THE CHASSIS ON A DESKTOP
Attach the four included rubber feet to the switch’s bottom. Then place the switch on a desktop.
3.1.5 INSTALLING THE CHASSIS INTO A 19-INCH WIRING CLOSET RAIL
CAUTION
Allow extra space for proper air ventilation for the cooling fan on both sides of the
chassis.
1. Wear a grounding strap to guard against electrostatic discharge.
2. Position the mounting brackets (included) on the switch’s front panel.
3. Attach four of the supplied mounting screws (two on the left, two on the right) to the switch’s sides to hold
the bracket in place (see Figure 3-2).

Figure 3-2. Chassis installation.
4. Position the chassis with mounting brackets attached in the 19-inch wiring closet rail.
5. Use the four remaining screws to connect the bracket-mounted chassis to the rail, then tighten the screws.
3.2 Cabling Requirements
3.2.1 TWISTED-PAIR PORTS
For either a Fast Ethernet or Gigabit Ethernet twisted-pair network connection, use Category 5 or 5e cable
that’s 328 feet (100 m) long or shorter. We recommend Category 5e cable for Gigabit Ethernet networks.
3.2.2 FIBER PORTS
Connect multimode fiber to the LGB200C-MLC module. Use single-mode fiber for the LGB200C-SLC10 or
LGB200C-SLC30.
12
CHAPTER 3: Installation
3.2.3 VLAN EXAMPLES
If VLAN is enabled and configured, each network node that can communicate with each other directly is
bound in the same VLAN area.
Example 1: Port-based VLAN
In Figure 3-3, VLAN is defined by what VLAN you are using. The switch supports both port-based VLAN and
tag-based VLAN. They are different in practical use, especially in physical location.

Figure 3-3. Port-based VLAN.
In this example:
• The same VLAN members can’t be located on different switches.
• Every VLAN member can’t access all other VLAN members.
• The switch manager has to assign different names for each VLAN group at one switch.

Parameter
VLAN Mode
Description
Choose Disable, Port-based, Tag-based, or Metro mode from the dropdown menu.
Disable will stop the switch’s VLAN function. This is the default setting.
Port-based VLAN is defined by port. Any incoming or outgoing packet
from any one port of a port-based VLAN will be accepted. For example,
suppose you have a port-based VLAN named PVLAN-1 that contains
ports 1–4. From port 1 you can communicate with ports 2–4. Each portbased VLAN you build must be assigned a group name. The switch can
support up to 16 port-based VLAN groups.

Parameter
VLAN Mode (continued)
Description
Tag-based VLANs identify their members by VID. This option considers
any Ingress or Egress list filtering rules required for the switch before
forwarding a packet.
Each tag-based VLAN must be assigned a VLAN name and VLAN ID.
Valid VLAN IDs are from 1 to 4094. You can create up to 16 tag-based
VLANs.
Metro mode is a quick configuration VLAN environment method used for
port-based VLANs. It will create 14 or 15 port-based VLAN groups.
Uplink Port
This option is only enabled when you select Metro mode from the dropdown menu in Figure 4-5.
When you select 15 from the drop-down menu: Except for port 15, each
switch port can’t transmit packets to each other. Each port groups a VLAN
with Port 15, so a total of 15 groups consisting of two members are
formed.
When you select 15 and 16 from the drop-down menu: Except for ports 15
and 16, each switch port can’t transmit packets to each other. Each port
groups a VLAN with port 15 and port 16. A total of 14 groups consisting of
three members are formed.
24
State
Available only if you choose Tag-based VLAN from the drop-down menu
in Figure 4-5. When you select Enable from the drop-down State menu,
only tagged packets with this VID can manage the switch.
