1. Introduction
The Fast Ethernet hub KF-4M provides four Fast Ethernet Twisted-
pair(TP) ports. Each port complies with 100BASE-TX standard and
isused for connectingto a 100BASE-TX device suchas a 100BASE-
TX hub or a computer equipped with a 100BASE-TX card. The hub
alsoprovides complete diagnostic LED indicators to indicate the ac-
tivity status of the hub and network ports.
The following figure illustrates the front and rear view of the hub:

• Installationguide
• Thehub unit
• One AC power adapter for the hub
Installation
The hub can be placed on a desktop as a stand-alone unit. It also can
be mounted on a magnetic-sensitive metal surface with its rubber
magnet stand on the hub's bottom.

Checking AC Power
One AC power adapter is contained in the hub package. 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 hub
shouldhave the AC voltage matching the commercialpower voltage
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 800mA min.
• DCplug type:
The power socket for the AC power adapter is located on the rear of
the hub as shown below:

3. Making Network Connections
Network Connectors
The TP ports are located on the front panel.
Network Ports
Four TP ports are presented by 4 RJ-45 jacks which are labeled
"1X","2X",.., and"4X" respectively.One RJ-45labeled "4I" next to
the "4X" jack is an alternative jack for the TP port #4.
