Switch Ports
There are twenty-four RJ-45 connectors on the front panel.The 10/100Mbps
speed and Full/Half duplex mode of each port are automatically determined
when you connect the switch to 10Base-T or 100Base-Tx devices.
Normal/Uplink Push Button
One Normal/Uplink push button is located at the right end of the front panel.
You can use it to change the connection mode of the 24th port on the switch,
for connecting to either a PC or a hub/switch.The default setting is in the
Normal (MDI-X) position, which is the “out” position.The port is configured
to connect with a PC when the button is in this position. When the push
button is pressed in (MDI), it allows you to connect with a hub or a switch
using straight-through twisted pair cable.

Rear Panel Information
Full/Auto Dip Switches
All of the ports are capable of auto-negotiation. In addition, each port has a dip-
switch on the back panel, which can be set to either auto-negotiation, or
enforced full duplex operation mode.
If you set a dip-switch to the
Auto
position, the operation mode is
automatically determined by the capability of the link partner. If the link

partner is not able to advertise its capability, the default operation mode is half
duplex.
If you set a dip switch to the
Full
position, the port can transmit and receive
data simultaneously. Full mode is used for point-to-point connections only.
The speed of the port is auto-sensing no matter which position you set the dip-
switch in.
ConnectingTo Network Devices
If you are connecting several workstations and a server, you can build the
network using the FriendlyNET Switch 4024P as shown in Figure 4.
Figure 4 A simple network topology
To improve the efficiency of the network, it is best to have 200Mbps full duplex
operation between the server and the FriendlyNET Switch 4024P, if the LAN
adapter on the server can operate in full duplex mode.
Connecting to a Switch or a Hub
Make switch-to-switch or switch-to-hub connections by connecting the 24th
port of the FriendlyNET Switch 4024P with straight-through cable (Category
3 for 10Mbps only, Category 5 for all others) to any port of the other hub/
switch; make sure the Normal/Uplink button is pressed in when you make this
connection. Make sure also that the dip-switch for the port on the
FriendlyNET Switch 4024P is set to
Auto
mode.

Figure 5 Multiple hub/switch network
For 100Base-T networks, the maximum network diameter is approximately
205 meters, assuming you are using UTP cable (Category 3 for 10Mbps only,
Category 5 for all others). The maximum length between hubs or hubs and
switches is 100 meters.
Placing or Rack Mounting the Switch
The FriendlyNET Switch 4024P is supplied with two mounting brackets, six
screws, and four rubber feet for mounting the rack or placing it on a flat surface.
Placing the FS4024P on a flat surface
1
Apply the four rubber feet to the bottom of the unit.
2
Put the unit on the flat surface.
Mounting the FS4024P in a Rack
1
Place a mounting bracket over the mounting holes on
each end of the unit.
2
Insert each screw through the bracket and into a mounting
hole in the switch, as shown in Figure 6.
3
Insert the unit into your 13-inch rack.
