16 or 24 RJ-45 10/100 Dual Speed Switching Ports
Connecting to a Desktop
There are 16 or 24 RJ-45 ports on the front panel. The
speed and full or half-duplex modes of the ports are
automatically determined when users connect the switch
to 10Base-T and 100Base-TX devices.
The 16 or 24 RJ-45 auto-negotiation ports simplify
migration of 10 Mbps Ethernet to 100 Mbps Fast
Ethernet.
Normal/Uplink Push Button
One normal/uplink push button on the front panel allows
users to select the 16
th
or 24
th
port to connect to a PC or a
hub or switch. With this normal/uplink push button
feature, users can connect with network devices.
A link LED is lit when there is a successful connection.
The default setting is in the normal (MDI-X) position, i.e.
the long button position. The port is configured to
connect wit h a PC using a straight through twisted pair
cable.
When the push button is pressed (MDI), i.e., the short
button position, connection is made with a hub or a
switch using a straight through twisted pair cable.
The switch is connected to the desktop, to form a small
network. You can build the network as shown in the
figure.
To improve the network efficiency, it is better to have 200
Mbps full-duplex operation between the server and
switch, if the LAN adapter on the server can operate in
full-duplex mode.
Connecting to a Switch or a Hub
Switch-to-switch or switch-to-hub connections are made
by connecting the 16
th
or 24
th
port to a port or to the other
hub or switch with the normal/uplink push button pressed
in.
With 100Base-TX, the maximum network length is
approximately 205 meters with UTP cable. The maximum
length between hubs or switch-to-hub is 100 meters.

This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict
accordance with the instructions provided with the equipment, may cause interference to radio and TV reception. The
equipment has been tested and found to comply with the limits for a Class A computing device in accordance with the
specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such
interference in a residential installation. However, there is no guarantee that interference will not occur in a particular
installation. If you suspect this equipment is causing inter ference, turn your switch on and off while your radio or TV is
showing interference. If the interference disappears when yo u turn the switch off and reappears when you turn the switch
on, something in the switch is causing interference.
You can try to correct the interference by one or more of the following measures:
! Plug the computer which has the equipment installed into a different power outlet so that the equipment and the
receiver are on different branch circuits.
! Reorient the receiving radio or TV antenna where this may be done safely.
! If necessary, you should consult the place of purchase or an experienced radio/television technician for additional
suggestions.
