CHAPTER 1 Introduction
1.1 Product Introduction
Congratulations on your purchase of the Lantronix 10/100Mbps 10­port or 18-port switch. The LSW2F8 and LSW2F16 10/100 Ethernet Switches are designed to give you the ultimate in performance, flexibil­ity, ease-of-use, and reliability.
The LSW 10/100 switches can increase performance on your network by bringing full Ethernet bandwidth to individual workgroups or straight to the desktop instead of requiring all stations to share the bandwidth of a single network. The LSW switchÕs 100Mbps Fast Ethernet capability can eliminate bottlenecks in connection to servers, or can link 10Mbps workgroups to a 100Mbps Fast Ethernet network backbone.
For straight-through 10BASE-T/100BASE-TX connections to servers and workstations, the LSW switches support full-duplex connections, effectively doubling the total throughput on individual links. The LSW switchÕs store-and-forward switching architecture forwards packets to their destination with a minimum of delay and eliminates bad packets from the network.
The LSW2F8/LSW2F16 switch can be placed on a tabletop or rack­mounted, and provides the ideal solution for your small, medium, or large Ethernet/Fast Ethernet network. These devices are designed to comply fully with the IEEE 802.3 Ethernet and 802.3u Fast Ethernet standards.

Chapter 2 Using the LSW Switch
2.1 Packing Checklist
Your switch product package should contain the following:
✓ An LSW2F8 or LSW2F16 10/100 Ethernet Switch ✓ One AC Power Cable ✓ Four self-adhesive standoffs ✓ Rackmount brackets and screws ✓ Installation Guide
If any of these items are missing, contact your dealer immediately.
2.2 Planning Your Network
Before you install your 10/100Mbps network, you should plan out how you wish to organize your network to take maximum advantage of its switching capabilities. This section discusses typical applications for the switch.

2.2.1 Fileserver Link
FULL/COL LINK/ACT
12 3456 78910
The LSW switch can be used to greatly increase the bandwidth between one or more fileservers and the workgroups they serve. Individual 10Mbps workgroup switches can be connected to the ports on the LSW switch, ensuring that traffic in one workgroup will not interfere with the performance of another workgroup. Full-duplex 100Mbps links to fileservers guarantee that full bandwidth is delivered to each work­group. High-performance workstations needing extra throughput can connect directly to the switch using a full-duplex 10BASE-T connection, giving 20Mbps of effective throughput.

2.2.2 Backbone Link
FULL/COL LINK/ACT
FULL/COL LINK/ACT
12 3456 78910
Traditionally, bridges and routers have been used to link individual local area networks into an interconnected network. Routers and tradi­tional bridges introduce relatively large delays when forwarding traffic from one network to another, in addition to being difficult to manage. Bridge architecture based on two-port bridges may require traffic to pass through several bridges before reaching its destination. Ethernet switches now perform these functions with especially small delays, making them ideal for backbone link applications. Compared to routers, LantronixÕs LSW Ethernet switches are easy to set up and maintain. Several networks can be connected together with a single Ethernet switch, and the forwarding delay is negligible. One or more of the LSW switchÕs 100Mbps links can be used as a high-speed backbone link to other switches serving as collapsed backbones.

The LSW 10/100 Ethernet Switch can allow you to gradually transition between traditional 10Mbps Ethernet and newer 100Mbps Fast Ethernet. The addition of the LSW switch can give immediate increases in performance on the 10Mbps networks, and allows connectivity to be maintained when network stations are transitioned over to 100Mbps Fast Ethernet.

The LSW 10/100 switches were designed for easy Òplug and playÓ installation. Before you connect your switch to other devices, there are several issues you should keep in mind:
▼ When connecting the LSW switch to a device using unshielded
twisted pair cable, you must make sure that the cable length is not greater than 100 meters
▼ 10BASE-T Twisted Pair Ethernet cabling should be Category 3 or better ▼ 100BASE-TX Twisted Pair Fast Ethernet cabling should use tested
Category 5 cabling
▼ Network cable segments can be connected to or disconnected from
the LSW 10/100 switch while the power is on
▼ When placing your LSW switch, you need to avoid dusty locations
and electromagnetically noisy areas

2.4 Mounting
FULL/COL LINK/ACT
12 3456 78910
Your LSW2F8 or LSW2F16 switch is delivered with two brackets for mounting the switch in an EIA standard 19-inch rack. Secure the mounting brackets onto the sides of the LSW switch, fastening them with screws as shown in Figure 2-6.
Figure 2-6 Mounting Bracket Installation
LSW2F8
If your site uses only a few switches and is not equipped with a mounting rack, you may choose to place the LSW switch on a table or wiring closet shelf. In this case, use the four self-adhesive rubber feet, which are provided with the switch for cushioning purposes. Stick them at the four corners of the bottom surface of the LSW switch to cushion it against vibration.

2.5 Connecting the LSW Switch
Use the following procedures to connect 10BASE-T or 100BASE-TX net­work devices to the LSW switch:
LSW2F8 Ports 2-9 Port 1 & Port 10 LSW2F16 Ports 2-18 Normal Uplink
PC, Workstation S S C
Server S S C
Hub, Switch port C C S
Hub, Switch uplink port S S C
S = Straight Cable C = Crossover cable
The following table describes the two cable types:
Straight cable Crossover cable
Pin 1 TD+ RD+
Pin 2 TD- RD-
Pin 3 RD+ TD+
Pin 6 RD- TD-
Make sure that the length of the straight-through cable between the switch and the other device does not exceed 100 meters, including all patch cables and cross-connect wires.
Duplex mode: each 10/100 port (Ports 1 and 2) can detect duplex mode automatically Ð the device being connected to must support 802.3u autonegotiation for full duplex to be used; duplex mode for 10Mbps ports can be selected via switches on the back of the unit.

3.1 Power LED
The LED on the front panel labeled PWR is used to indicate that the switch is receiving power and is turned on. If the LED is off, check the following to isolate the problem:
▼ Make sure the power cord is properly connected to the power outlet
and is properly inserted into the power connection on the switch
▼ Determine whether or not the outlet is functional by plugging
another device into the receptacle
▼ Turn the power switch to the ON position. If there are no problems
and the LED still does not light, contact your dealer
Full-
3.2 10/100 Mbps LEDs
Each 10/100 port (Ports 1 and 2) have the 10/100Mbps LED on the front panel. When the LED is ON, it indicates the port is in 100Mbps mode. Otherwise, its working in 10Mbps mode.
12
3.3 Full/Col: Full or Half Duplex/Collision LEDs
Each port has a full duplex/half duplex/Collision LED on the front panel labeled Full/Col. On normal status, this LED indicates that trans­mission of selected ports is full duplex or half duplex (ON: Full duplex, OFF: Half duplex). Also this LED is used to indicate collision status. When two or more stations on the network segment attempted to trans­mit at the same time, a collision occurs, all of the stations involved in the collision will recognize the collision, wait a random amount of time, and retransmit. At this moment, this LED will blink on briefly.
3.4 Link/Activity LEDs
Each port on the LSW2F8 and LSW2F16 has a Link/Activity LED which indicates whether a device is detected on the other end.
When the port is in Link OK status, this LED also used to indicate activity on the network segment. Whenever data is transmitted and/or received through the network segment that the port is connected to, the LED should blink on briefly.
LED summary table
PWR Green ON=Unit is receiving power
10/100Mbps Green ON=100Mbps; OFF=10Mbps
Full/Col Yellow ON=Full Duplex; OFF=Half Duplex;
Flashing=Collision
