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:

Installing & Network Connection

Installation

Þ The fiber TX, RX cables must be paired at both ends.

Þ Repeat the above step, as needed, for each fiber port to be connected to

a 100Base-FX device.

Þ The fiber port can be up-linked to an upper level hub's port.

ÞVerify 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

2-2

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:

100Base-TX 100Base-FX
