Dual Speed Hub
User’s Guide
Introduction
Congratulations on your purchase of a FriendlyNET dual speed hub.This 24-
port hub complies fully with IEEE802.3 and IEEE802.3u standards.
All ports accept twisted-pair cable and provide automatic media detection and
auto-negotiation of 10Base-T or 100Base-TX devices.The hub also provides an
uplink push button for the 12th port, which can be cascaded to another hub via
straight-through cable.
The dual speed hub can be placed on a tabletop or rack mounted. With
unmatched flexibility, it ensures efficient operation in any LAN environment,
regardless of size.
Features

If the power LED is OFF, check the following to isolate the problem:
❑ Make sure the power cord is properly connected to the power outlet
and is properly inserted into the power connection on the hub
❑ Determine whether the outlet is functional by plugging another
device into it

Hub Ports
There are twenty-four RJ-45 connectors on the front panel.The 10Mbps
or100Mbps speed of each port is automatically determined when you connect
the hub 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 12th port on the hub, for
connecting to either a PC or another hub.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 another hub using straight-
through twisted pair cable. See “Interconnecting Hubs” for details.
Rear Panel Information
The following sections describe the elements of the rear panel of the
FriendlyNET 2024P Dual Speed Hub.

Power Cord Connector (100-240VAC)
The power cord connector may be connected to any power source within the
indicated voltage range.The internal power supply switch will automatically set
the appropriate voltage.
Power Control Switch
Use this switch to power the unit off when connecting it to a power source, and
power it on when it is properly connected to power.Installation
Thefollowingsections covertheproceduresyou needto followin orderto place
your FriendlyNET 2024P Dual Speed Hub and connect it to workstations or
other hubs.
Placing or Rack Mounting the Hub
The FriendlyNET 2024P Dual Speed Hub 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 Hub on a flat surface
1
Apply the four rubber feet near the four corners of the
bottom of the unit.
2
Put the unit on the flat surface.
Mounting the Hub 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 hub as shown in Figure 4.
3
Insert the unit into your 13-inch rack.

Connecting Stations to Hub Ports
Use the following procedure to connect a 10Base-T or 100Base-TX Ethernet
server or workstation to the hub.
Keep in mind that you can connect or disconnect network cable segments from
the hub while the power is on. plugging in or removing network cables while
your hub is running will not interrupt the operation of the hub.
1
Make sure that the length of the straight-through cable
between the hub and the station does not exceed 100
meters, including all patch cables and cross connect wires.
10Base-T twisted pair Ethernet cabling should be to Cate-
gory 3 standards, and 100Base-TX twisted pair Fast Eth-
ernet cabling should be to Category 5 standards.
2
Connectoneend ofthe cableto the RJ-45connector onthe
hub, and the other end to the workstation or server, as
shown in Figure 5.

Interconnecting Hubs
Use the following procedure to connect your FriendlyNET 2024P Dual Speed
Hub to another hub in a cascading configuration.
1
Obtain a straight-through cable (Category 3 for 10Mbps
only, Category 5 for all others) that does not exceed 5
meters in length, including all patch cables and cross con-
nect wires.
2
Connect one end of the cable to the 12th (uplink) port of
your hub.
3 Connect the other end of the cable to any port of the other
hub except the uplink port on that hub.The connections
should be as shown in Figure 6.
4 Press the Uplink button next to the 12th port on your hub.
Figure 6 Interconnecting two hubs
You can connect hubs together using other ports than the uplink port, but in
this case, you must use a cross-over cable.
