Introduction  
Overview  
The Levelone 8/16 Port Fiber Switch is a standard switch that meets all IEEE  
802.3u/802.3x specifications. Fast Ethernet Switch is a cost-effective solution for  
easing your network congestion problem on existing shared-hub network by  
breaking up the collision domain and by multiplying the network performance. The  
overall network transmission speed is increased and the network efficiency is  
improved to accommodate high-bandwidth applications, such as imaging,  
multimedia, and CAD/CAM, etc.. Four models are available:  
8 Port 100Mbps Fast Ethernet Switch with SC Connector  
8 Port 100Mbps Fast Ethernet Switch with ST Connector  
FSW-0800FXC  
FSW-0800FXT

The fiber TX, RX cables must be paired at both ends.  
Repeat the above step, as needed, for each fiber port to be connected to  
a 100Base-FX device.  
The fiber port can be up-linked to an upper level hub's port.  
Þ
Þ
Verify that the voltage of AC power is correct and plug in AC power cord.  
Note:  
1. Both local and remote link devices (mode) must operate at the same  
transmission mode and speed  
After the hub is powered off, wait at least 10 seconds before powering it  
on again  
Network Parameter for 100Mbps Fiber  
To help ensure a successful installation, you must observe the following cabling  
parameter. Violating these rules can render the LAN to work poorly.

Troubleshooting  
Network troubleshooting requires patience and logic. Generally speaking, the  
cabling and workstation configurations are the likely first suspects; network  
hardware is usually last on the list. The nature of the hub design dictates that it is  
more likely for an entire hub to fail instead of just a single port.  
Cabling Problems  
Improper Cabling is the primary cause of most non-workstation problems on  
Ethernet network, particularly for 100 Base-FX networks. It must be emphasized  
that genuine twisted-pair cable and fiber optic cable be used to avoid many types  
of cabling problems  
Wiring is definitely the problem if the Link LED does not light when the fiber  
plug from a workstation is inserted into the port jack. Either correct the break  
in the wire or replace the wire before proceeding  
Multi or single-mode fiber cable should match the switch's fiber transceiver.  
If a workstation (workstation A) does not work and other 100Base-X ports on  
the hub are functioning, remove a fiber plug from a functioning port with a  
functioning workstation (workstation B) and insert it into the suspect port. If  
workstation B still works, the problem is in workstation A or in the wiring.  
However, if workstation B does not work, then the hub may have a defective  
port. Even if you suspect a defective port on the hub, continue testing.  
Improperly wired workstations may appear to be functional, especially if they  
are located near the hub. Sometimes, a port connected to an improperly wired  
workstation can function marginally while another port may not work at all  
Once you have established that the hub is working properly, check all wiring  
between the hub and the malfunctioning workstation. Ensure that the transmit  
and receive wires have not been crossed; the two transmit wires should be  
paired together as should the two receive wires  
Use a continuity checker to ensure that wires do not have breaks. By shorting  
together the two wires of a pair at one end, you can use the continuity checker  
at the other end. Also, check that there are no shorts between wires

Workstation Problems  
Most non-cabling problems result from improper configuration of the network  
interface card (NIC) and its corresponding driver. The following points will be  
helpful:  
Like other add-on cards in the workstation or server, NIC must have unique  
memory address, I/O address, and interrupt. The settings on a particular card  
must not conflict with the settings on any other card in the same station.  
Please refer the User's manual of the NIC, computers, and Networking  
operating systems to determine the proper configuration  
The selection of half or full duplex, the speed of 10 or 100Mbps for the NIC  
setting must match the mode and speed setting of the corresponding port of  
the Hub. For NWay Auto-Negotiation setting, both link partners will auto-adjust  
to the highest allowable speed and mode operation  
Other Problems  
Other specific problems may be diagnosed by using the LEDs, as below.  
Power LED is off when the AC Power switch is ON:  
Defective power supply unit or fuse  
Incorrect AC voltage  
Defective Hub  
Link/Act LED is off at any Fiber:  
Faulty node or wiring connection  
For fiber - the "TX", "RX" cables should be paired at both ends  
No Link signal is received from the remote node/site  
100Base-X Port at irregular traffic:  
Abnormal or invalid transmission status(mode / speed) between local and  
remote link partners, i.e., full-duplex port is connecting to a half-duplex port,  
or 10Mbps port is connecting to a 100Mbps device  
Hub Diagnostic Test  
The switch hub performs self-diagnostic test at major hub modules upon  
power on, LED indicators will go to normal status if no problem occurred  
To reset or restart the hub, power off the hub and wait for 10 seconds, then  
power on it again

For connection to Router, Bridge, or regular 100Base-X Hub, please refer to the  
device’s Technical Manual for respective bit-time delay.  
Switch Hub Cascading and Long-Haul Connection  
Theoretically, the switch hub breaks up the collision domain in hub cascading that  
you may up-link the hubs unlimitedly. In practice, the network extension  
(cascading levels & overall diameter) is limited by the timing requirement--time-out  
specification--of your application software and network operating system.  
A hierarchical network with minimum levels of hub may reduce the timing delay  
between server and client station. If more than two hubs are connected in the  
same room, select one hub as Level 1 hub and connect all other hubs to it at Level  
2. Server/Host is recommended to connect to the Level 1 hub. By following this  
approach, it will minimize the number of hubs in any one path and will improve  
network efficiency. (See Fig. 2-1)  
The fiber switch(single mode transceiver) with single mode fiber can provide the  
long haul connection up to 15km per segment, you may extend the distance by  
cascading the switch and meet the timing requirement of your application  
software. Sum up all elements’ bit-time delay and the overall bit-time delay of  
wires/devices must be within 512 bit in a 100Base-X network segment (collision  
domain). The fiber cables and devices’ bit-time delay(round trip) is as below:
