Introduction 1
KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company
Introduction
Intended Audience: This manual assumes that the user has a general working
knowledge of networking principles and architecture and is familiar with
network systems in general.
Congratulations on the purchase of your new Kingston Fast EtheRx
10/100BASE-TX 19” Rack-Mountable Fast Ethernet Switch, model
KNS1600/R. The Fast EtheRx Switch is a high-performance 10/100BASE-TX
switch ideal for the small-to-medium businesses. The Fast EtheRx Switch has
sixteen (16) UTP ports that auto-negotiate speed detection for 10/100BASE-TX
and half-duplex / full-duplex mode operation. It is basically designed to allow
Standard 10BASE-T Ethernet networks to communicate with 100BASE-TX
Fast Ethernet networks and to segment both 10Mbps and 100Mbps networks.
The Fast EtheRx Switch complies with IEEE802.3u 100BASE-TX, IEEE802.3i
10BASE-T, and IEEE802.3 CSMA/CD Ethernet Standards.
The Fast EtheRx Switch may be used in both standard desktop and 19” rack-
mount installations (using the mounting brackets provided with the unit) and
requires no hardware or software configuration.
The last port on the Fast EtheRx Switch has two RJ-45 connectors to support
UTP cabling in the straight through and/or crossover wiring configurations.
For easy recognition of network status and troubleshooting, the front panel
includes a variety of diagnostic LEDs including Power, 100TX Speed
Detection, Link, Receive, Transmit, Collision, and Full-Duplex status.
For the remainder of this manual, the KNS1600/R will be referred to as the Fast
EtheRx Switch.

Design Features 3
KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company
Compliance Standards
The Fast EtheRx Switch complies with the 10/100Mbps functions as defined by
IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD
Ethernet standards.
Design Features
Switching Function
The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-T
Ethernet networks to 100BASE-TX Fast Ethernet networks and to segment 10Mbps
or 100Mbps network segments.
Auto-Negotiation
Auto-Negotiation provides the means of automatically establishing a link by
detecting the link capabilities of the connected device on the network to select the
best operational mode available (i.e. 10/100BASE-TX selection, half- / full-duplex
mode operation, etc.)
Full-Duplex
Full-Duplex transmission means that dedicated inbound and outbound channels are
established for bi-directional transmission of data. This allows the collision
detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission
delay normally caused by listening, collisions, and packet resends when operating in
half-duplex mode.
Store-and-Forward Switching
The Fast EtheRx Switch uses a packet-forwarding method called Store-and-
Forward, which minimizes the re-transmission of faulty data packets. This means
that the Fast EtheRx Switch can store the incoming frame in an internal buffer and
check the packet for errors before sending it out to the destination port. If the frame
does contain errors, it will be discarded and then retransmitted.
Flow Control
The Fast EtheRx Switch implements a collision-based flow control mechanism that
reduces the risk of data being lost at the congested ports. This is accomplished by
forcing a collision with the data frames on all ports once the free-buffer queue has
reached the pre-set minimum.

Hardware Installation
Before you begin installing network cables, please take a few moments to
familiarize yourself with Fast EtheRx Switch. The functions on the front and
rear panels are illustrated in the following sections.

Front Panel
Power LED
The PWR LED indicates the power status of the Fast EtheRx switch. The LED
will light up steady green when the AC power cord is connected to the unit
from a power source and the power switch on the unit has been turned on.
100BASE-TX (100TX) LED
The 100TX LED will automatically light up when 100Mbps operation is
detected. This LED will not light up if 10Mbps operation is detected.
LINK/ACT LED (for both 10 and 100Mbps)
The LINK/ACT LED uses a single LED to display two functions. A steady
green light indicates that a good link has been established, and a flashing green
light indicates when data is being received or transmitted. If the LED does not
display solid green indicating a good link, check the following:
1. Make sure that the power is turned on for both the Fast
EtheRx Switch and the attached device.
2. Verify that the drivers for the network adapter have been
loaded on the PC. Some network adapters require that the
driver be loaded before establishing a proper link.

3. Make sure the cable is wired properly and connected on both
ends.
4. Make sure the correct cable type has been selected.
5. If steps 1 through 4 are correct, please check the cable, as it
may be defective or wired incorrectly. Replace the cable and
try again. Please refer to Appendix A for Pin Assignments
and Appendix B for Cabling Guidelines.
Full Duplex and Collision LED
The FDX/COLL LED uses a dual color LED to display two functions. A solid
green light indicates that Full-Duplex operation has been detected. A flashing
amber light indicates that a collision has occurred in half-duplex mode. Full-
Duplex mode is auto-negotiated on all UTP ports.
UTP Ports
The Fast EtheRx Switch has sixteen (16) 10/100Mbps UTP ports that auto-
negotiate 10/100BASE-TX connections and half- or full-duplex mode
operation. The last UTP port has two RJ-45 port connectors for support of
UTP cabling in the crossover or straight-through wiring configuration. Only
one of the two ports may be utilized.
The RJ-45 port marked is internally crossed like all other UTP ports. By
default, all repeater and switched UTP ports are generally configured as
standard MDI-X, or internally crossed ports. With a straight-through cable, this
port can be used for cascading to a standard MDI device, such as a network
adapter or router. With a crossover cable, this port can be used for cascading to
another MDI-X device, such as a hub.
