1. Introduction
KF-8D dual-speed Fast Ethernet/Ethernet hub is designed to allow
easy and flexible migration from 10Mbps Ethernet to 100Mbps
Fast Ethernet. The hub complies with IEEE 802.3 and IEEE 802.3u
repeater specifications and supports 10Mbps and 100Mbps con-
nectivity over UTP cabling in the same hub. The hub provides 8
dual-speed TP ports. All of the TP ports support auto-sensing
function that allows the hub to detect the connection speed auto-
matically.
The hub also provides complete diagnostic LED indicators to indi-
cate the activity status of the hub and network ports.
The following figure illustrates the front and rear view of the hub:

Features
• Complies with IEEE 802.3 and IEEE 802.3u standard for
Ethernet/Class II Fast Ethernet repeater
• Provides a configuration switch (10M/100M/AUTO) to set all
8 TP ports as 10BASE-T ports, 100BASE-TX ports or 10/100
auto-sensing ports.
• In AUTO mode, each TP port can support either an Ethernet
10Mbps connection or a Fast Ethernet 100Mbps connection
with auto-sensing the connection speed.
• The hub provides one uplink jack that allows easy linking of
two hubs via straight-through UTP cable.
• The TP ports are implemented with auto partition and
reconnecting function to protect the network from failure
caused by consecutive collisions from a specific port.
• The jabber function is implemented to prevent reception of
illegally long packet, which would degrade network perfor-
mance.
• Compact design suitable for small workgroup
• Specifications
Power: +12V 1000mA min.
Dimension: 194 mm x 116 mm x 20 mm (WxDxH)
Temperature: 0oto 40oC when operating
Humidity: 10% to 90% non-condensing when operating

Dual-speed Hub Technology
Dual-speed hub is designed to support connections with different
speeds in the same hub. It makes a network planning simpler, espe-
cially when an environment is containing 10Mbps Ethernet and
100Mbps Fast Ethernet technologies. It also allows a smooth mi-
gration from an Ethernet network to a Fast Ethernet network.
A dual-speed hub is actually equipped with one 10Mbps repeater
and one 100Mbps repeater in one hub unit. Each repeater serves
one shared network segment. The repeater receives transmissions
from any of its ports and retransmits them to all its other ports. The
TP port of the hub can auto-sense the speed (10M or 100M) of its
connectionand switch toeither10Mbps shared segmentor100Mbps
shared segment automatically. The internal design of a dual-speed
hub is illustrated as follows:

2. Installation
Unpacking
Check to see that you have everything before you start the installation.
• Installation guide
• The hub unit
• One AC power adapter for the hub
• One wall mount kit
Checking AC Power
Before you begin the installation, check the AC voltage of your area.
The AC power adapter which is used to supply the DC power for the
hubshouldhave theACvoltagematchingthecommercialpowervolt-
age in your area. The specifications of the AC power adapter are:
• AC input power: AC power voltage of your area
• DC output power:+12 VDC 1000mA min.
• DC plug type:
4

The power socket for the AC power adapter is located on the rear of
the hub as shown below:
Mounting the Hub
The hub can be placed on a desktop as a stand-alone unit. It also can
be mounted on a wall. The following procedure describes how to
mount the hub onto a wallboard or wood (a stud, heavy wooden
paneling, etc.) using the wall mount kit supplied in the hub package:
1. Using the slot bracket and two washer-head screws in the wall
mount kit, screw the slot bracket onto the bottom of the hub in
any one of the four directions.
2. Using the mount bracket and two pan-head self-tapping screws
in the kit. Screw the mount bracket onto the wall.
