Introduction
The 10/100 Fast Ethernet Switch is an ideal device for linking Ethernet
LANs without impacting available bandwidth or for integrating 100Mbps
Fast Ethernet with 10Mbps Ethernet networks. The speed migration design
will bridge a bandwidth-intensive Fast Ethernet network and a traditional
10Mbps Ethernet network.
The 10/100 Fast Ethernet Switch complies with IEEE802.3u, 100BASE-TX,
IEEE802.3 and 10BASE-T standards. The switch has two ports, one of
which is a 10/100Mbps, N-Way, RJ-45 port. The other is a 3-in-1 combo
port with twisted pair (10/100Mbps, N-Way), BNC coaxial, and AUI
connectors. The 10/100 Fast Ethernet Switch provides a store-and-forward
passing scheme with filtering and forwarding rates running at wire-speed,
reducing latency within and across segments.
The 10/100 Fast Ethernet Switch provides an easy, affordable, high-
performance, seamless, and standard-based migration path to a 100BASE-TX
LAN while preserving your initial investment and use of 10Mbps Ethernet
LANs.

2 Overview
Product Features
The 10/100 Fast Ethernet Switch has the following key features:
• One 3-in-1 Combo Port: UTP/STP (N-Way), BNC, and AUI.
• One 10/100Mbps, N-Way UTP/STP port.
• Full-duplex and half-duplex capability on both ports (applies only to the
twisted-pair connector on the combo port); user-configurable through
the Duplex Mode Switch.
• Support for IEEE 802.3, 10BASE-2, 10BASE-T, IEEE 802.3u and
100BASE-TX standards.
• Ability of both ports to connect to a LAN segment up to 100 meters long
(UTP/STP).
• Εxtensive LED indicators to facilitate troubleshooting and monitoring of
the product’s operating status.
•
••
• Compatibility with standard Ethernet applications, internetworking
systems and client-side adapters to minimize infrastructure changes and
costs.

Ports
The product comes with two ports. These ports can be used to connect to
individual stations, to LAN segments that include multiple hubs, and to other
100BASE-TX/10BASE-T switches.
Important Note: Crossover cables must be used when
connecting hubs or switches to the twisted pair ports
on this switch via any port other than a straight-
through uplink.

4 Overview
Port 1: 3-in-1 Combo
Port 1 has three different connectors – UTP/STP, BNC, and AUI.
The twisted-pair connector (UTP/STP) of Port 1 is a 10/100Mbps, N-Way
RJ-45 port for use with unshielded or shielded twisted-pair cabling. Because
it is an N-Way port, the operating mode of connected stations (10Mbps
Ethernet or 100Mbps Fast Ethernet) is automatically detected and the port is
auto-configured to match. Please use crossover cabling unless you are
connecting to a straight-through uplink port on a switch or hub. The
twisted-pair connector operates at an user-selectable effective speed of 10 or
100Mbps for half-duplex mode and 20 or 200Mbps for full-duplex mode. In
either mode, the twisted-pair connector can operate up to 100 meters of
Category 3, 4, or 5 UTP/STP cable.
The BNC connector is a standard connector for use with thin Ethernet coaxial
cabling (half-duplex mode only).
The AUI connector is for attaching the switch to an external transceiver for a
thick Ethernet or Fiber-optic connection (half-duplex mode only).
Important Note: The Port 1 connectors are arranged in a
“priority” scheme. That is, one connector has a higher
priority than the other two, so if a device is connected
to that connector, the other connectors are disabled.
The priority is: UTP/STP – highest priority; AUI –
second priority; BNC – lowest priority. Only one
connector at a time may be used.

10/100 Fast Ethernet Switch User’s Guide
Overview 5
Port 2: 10/100Mbps, N-Way UTP/STP
Port 2 operates at an user-selectable effective speed of 10 or 100Mbps for
half-duplex mode and 20 or 200Mbps for full-duplex mode. It is an N-Way
port, so it auto-detects and auto-configures according to the operating
standard (10Mbps Ethernet or 100Mbps Fast Ethernet) of connected devices.
Port 2 can operate up to 100 meters of Category 3, 4 or 5 shielded twisted-
pair or unshielded twisted-pair (STP/UTP) cable. Please use crossover
cabling unless you are connecting to a straight-through uplink port on a
switch or hub. Port 2 uses an RJ-45 connector.

6 Overview
LED Indicators
The 10/100 Fast Ethernet Switch has extensive LED indicators to facilitate
monitoring and troubleshooting. They include a Power LED and Status
LEDs for both ports. The Status LEDs have indicators that report on Link,
Duplex, Activity, Collision and 100Mbps states.
Figure 2 : LED Indicators
The following section describes these indicators in detail.
• Power LED
This indicator is green when power is supplied to the device. The Power
LED lights when you connect the power cable to the power receptacle at
the rear of the device, and then plug it in to a power outlet.
• Link/Act LED
This indicator is green when the respective port is properly connected to
a powered-on device and blinks green when packets are being
transmitted or received. If the AUI or BNC connector of port 1 is used,
this LED will not light to indicate the connection, but it will blink to
indicate packet transmission and reception.

10/100 Fast Ethernet Switch User’s Guide
Overview 7
• 100M LEDs
These indicators are green when port 1 or port 2 is connected to a device
operating at 100Mbps. If either of these LEDs is off, then the port it
corresponds to is either not connected or is connected to a device
operating at 10Mbps.
• FDX/Col (Collision) LED
This indicator is green when the respective port is operating in full-
duplex mode, and blinks yellow when collisions occur.
Rear Panel
The rear panel of the 10/100 Fast Ethernet Switch includes the power cable
connector and the Duplex Mode Switch.
Figure 3 : Rear Panel
Duplex Mode Switch
The 10/100 Fast Ethernet Switch must be set to the proper duplex mode for
both ports. To change the duplex mode, change the Duplex Mode DIP
switch setting on the back of the 10/100 Fast Ethernet Switch. On the DIP
switch, down is half-duplex, up is full-duplex, and the switch numbers
correspond with the port numbers.
