16 or 24 RJ-45 10/100 Dual Speed Switching Ports
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 with 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.
Connecting to a Desktop
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.
