●How Switching Hubs differ from Repeater Hubs
Ordinary repeater hubs transmit data to all ports, even when only one port
needs the data. Consequently, the overall network traffic increases, slowing
down communications on the network itself. Moreover, repeater hubs
require that all ports share the same bandwidth; a collision occurs when
multiple packets are transmitted simultaneously. To counter these problems,
the switching hub learns the destination address and sends data only to the
port that leads to the destination node. This scheme prevents the data from
being sent to other ports, thereby reducing network load. A switching hub
thus allows more efficient communication among computers on the network
1-4 Different between repeat hub and switch hub1
FX-05SC
●Switching scheme
Most switching hubs support one of the following switching schemes: Cut
Through and Store & Forward. In Cut Through switching, any received
packet is sent to one of the ports immediately after its destination address is
discerned. Since packets themselves are not inspected, some error packets
may leave the switch among normal packets. In contrast, Store & Forward
technology first stores a received packet in an internal packet buffer and
checks for length and CRC. Error packets are dropped at this stage, and
only normal packets are transmitted. The FX-16N Switching Hub supports
Store & Forward.
●About Flow Control
The Switch also supports the flow control feature for preventing packets
from overflowing the packet buffer. The flow control technology used in
half-duplex mode is called “Back Pressure”, while the flow control used
in full-duplex operation is called “IEEE 802.3x”. In Back Pressure, a
collision signal is sent out whenever the packet buffer becomes full. On the
other hand, a switching hub with IEEE 802.3x support transmits a “pause”
command to the source node to stop the data flow itself. To utilize
IEEE802.3x flow control, the attached network card must also support
IEEE802.3x flow control. (PCI’s FNW-9802-T fast Ethernet adapter card
supports this standard.)

●Limitations on Cascading Hubs
Generally, repeater hubs can cascade only up to four stages for 10BASE-T
and two stages for 100BASE-TX. This limitation does not apply to a
switching hub because each port on the switch has its own collision domain.
For this reason, switching hubs can expand an existing network without
using relatively more expensive routers or bridges.
Equipped with these advanced features, switching hubs can provide much
greater network traffic efficiency and expandability compared with ordinary
repeater hubs.

Note: When Port 1 is in use, do not use the uplink port. Also, do not plug a
phone jack connector into any RJ-45 port. This may damage the switching
hub.
4. Verify that either the Link/Act LED or 100M LED of the port is turned on
(or blinking). The Link/Act LED illuminates if a valid 10BASE-T link is
established. Similarly, the 100M LED is turned on if a 100BASE-TX
device is attached to the device.
You can connect an additional hub to the FX-05SC via a twisted-pair cable
to increase the total number of ports (nodes in your network). This scheme
is called “cascading”.
1. Prepare a straight-through cable with RJ-45 plugs. Cable type must be
Category 5 if you are adding a device with 100BASE-TX support. If the
other device is for 10Mbps connection, you may use Category 3 or
greater. (Network cables available from PCI: UTP-xx-05, UTP-xx-DT,
STP-xx-05)

1. Attach the supplied AC power adapter to the power jack on the rear
panel.
2. Connect the power adapter to a wall outlet.
3. Verify that the Power LED on the front panel is turned on.
Note:
Please make sure to use the AC adapter included in the product package.
The warranty does not cover any damage incurred by the use of any another
AC adapter.
1. Install a 10BASE-T/ 100BASE-TX network adapter card and driver in
each computer you want to network.
2. Prepare a twisted-pair cable with RJ-45 plugs at both ends. Cable length
should not exceed 100 meters, and cable type must be Category 5 if you
are using a 100BASE-TX network card. If the network card is for
10Mbps connection, you may use Category 3 or greater. (Network cables
available from PCI: UTP-xx-05, UTP-xx-DT, STP-xx-05)
3. Attach one end of the cable to the RJ-45 port on the computer’s network
adapter, and the other end to any of Port 1-5 of FX-05SC. Using the hub
in a stand-alone configuration, you can network up to 5 computers.

※About Uplink port
An uplink port is used to connect to an additional hub, and its wires are
cross-linked inside the hub. The following table shows valid port/ cable
type combinations. Please refer to this table if you plan to cascade an
additional hub in any different manner.
Note:
●Should you experience any problem in establishing a data link on any of
the ports, please refer to Appendix A and B for troubleshooting.
●Be sure to use Category 5 UTP cables for 100BASE-TX connection.
Similarly, use Category 3 (or greater) cables for 10BASE-T connection.
The maximum cable length is 100 meters. If the Uplink port is in use,
Port 1 may NOT be used.
2. Connect one end of the cable to the uplink port on the FX-05SC.
3. Connect the other end of the cable to any of the 100BASE-TX/ 10BASE-
T RJ-45 ports on the other device. The Link/Act LED illuminates if a
valid 10BASE-T link is established. Similarly, the 100M LED is turned
on if a 100BASE-TX device is attached to the device.
Note:
When using the Uplink port, do not use Port 1. Also, be sure to verify the
port type of all the routers/ switches before attaching any cable.
4. If you wish to cascade two or more hubs to the FX-05SC, be sure to
connect the Uplink ports of the other hubs to Port 1-5 of the FX-05SC. If
there is no Uplink port on the other hubs, use a crossover cable to attach
the hubs.

The FX-05SC can be easily monitored through its LED indicators. Please
follow the troubleshooting steps below to solve any problem you may
encounter during installation or implementation of the FX-05SC.
1. Verify system power first:
●Be sure the power is turned on for the switch and all attached devices.
●Power off the switch, wait for five seconds, and turn it on again.
●If the power indicator is not lit after power on:
Check the power source and attached cable. If the problem cannot be
resolved, please contact your local PCI reseller for assistance.
2. Perform the following tests:
●Please check whether the RJ-45 cable is functional. Replace with another
working cable, and see whether the condition can be improved. (Be sure
to use the correct cable type: for 100BASE-TX, you must use Category 5
cables.)
●Use another port on the FX-05SC. If a link can be established this way,
the first port is faulty. Please contact your local PCI reseller for
assistance.
●Make sure that all devices are connected to the network.
●Please ensure that the network adapter cards installed in the workstations
or other devices attached to the hub are in good working condition.
●Verify that Port 1 and Uplink port are not used at the same time.

Troubleshooting

The STP ports on FX-05SC support “Auto-negotiation”feature. This
technology automatically sets the best possible bandwidth when a
connection is established with another network device (usually at Power On
or Reset). This is accomplished by detecting both the transmission mode
and speed immediately after both devices are connected. With Auto-
negotiation support, the FX-05SC can handle both 10Base-T and 100Base-
TX devices in either Half- or Full-Duplex mode.
There is a non-standardized technology called “Auto-sensing”. Unlike
Auto-negotiation, Auto-sensing detects only the 10BASE-T - 100BASE-TX
speed modes (CANNOT recognize the duplex modes). Sometimes a
network card or hub with Auto-sensing support may fail to establish a valid
link with the FX-05SC. Should you encounter this problem, please disable
the Auto-sensing function of the card or hub and set its transmission mode
to 100Mbps half-duplex. Then, reboot the system (PC with the network card
or hub) and see whether a link can be established between the device and
the FX-05SC.

Two or more hubs can be connected via twisted-pair cables to provide
additional ports for PCs/ network devices. This scheme is called “cascade
connection”or cascading. Any two 100BASE-TX repeater hubs can be
cascaded as long as they comply with IEEE802.3u 100BASE-TX Class II
standard. However, certain restrictions apply to cascading multiple
10BASE-T/ 100BASE-TX repeater hubs. Great attention should be given
to 100BASE-TX cascading as their restrictions are more severe compared to
those applied to 10BASE-T cascading. Please see the table below and
Figure C-1 and C-2 for more information on cascading limitations for
10BASE-T/ 100BASE-TX networks.
A switching hub can be inserted in the network to relieve these limitations.
Once inserted in a network, the switching hub can “reset”the node-to-
node distance as well as the cascading stage count. In the case of
100BASE-T, the user can extend a network to an infinite distance as long as
a switching hub is used every 205 meters (see Figure C-3 below). Similarly,
it is possible to construct an infinitely long 10BASE-T network so long as a
switching hub is used every 500 meters.
