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

Apply the four rubber feet to the bottom of the unit.

Put the unit on the ﬂat surface.

Mounting the FS4024P in a Rack

Place a mounting bracket over the mounting holes on

each end of the unit.

Insert each screw through the bracket and into a mounting

hole in the switch, as shown in Figure 6.

Insert the unit into your 13-inch rack.
