FiberOptic Switches

Quick Installation Guide

This quick installation guide provides instructions for installing a

FiberOptic Switch.

1-1 Introducing the FiberOptic Switches

SIIG's line of fiber optic switches are standard switches that meet all

IEEE 802.3u/802.3X standards. A Fast Ethernet Switch is a cost-

effective solution for easing your network congestion problems on

existing shared-hub network by breaking up the collision domain

and by multiplying the network performance. The overall network

transmissionspeedisincreasedandthenetworkefficiencyisimproved

to accommodate high-bandwidth applications, such as imaging

multimedia, and CAD/CAM, etc.

2-1.1 Fiber Port Full-/Half-duplex Mode Configuration

Eachfiberportcanbeindependentlyconfiguredforeitherfull-duplex

(FDX) or half-duplex (HDX) mode through DIP switches located on

the front panel. The default setting is Full-duplex.

• Verify that the duplex mode setting for each fiber port on

the Switch hub matches the connected remote device's mode

setting (full-duplex to full-duplex, half-duplex to half-duplex).

• The number on the DIP switch corresponds to the fiber port

number it sets.

To change a fiber port's mode setting , power down the Switch unit

and set the appropriate DIP switch. Then, power ON to set the new

configuration and status.

Default DIP Switch Settings

2-1.2 Network Device Connections

Proceed with the following steps to make the network connections:

1. Turn OFF the power to the server/host, workstation or any other

device to be connected.

2. Using Fiber Cable for 100Base-FX devices and Cat 5 TP Cable for

10/100Base-TX devices, connect each device to the appro-

priate fiber/RJ-45 ports on the Switch hub .

NOTE FOR FIBER CONNECTIONS: When connecting fiber

cable, you must make a paired connection to each fiber port.

Connect a cable between the selected Switch port's Tx (transmit)

port and the remote device's Rx (receive) port. Connect another

fiber cable between the Switch port's Rx (receive) port and the

device's Tx (transmit) port.

NOTEFORMODELS8020-ST/SC:Thefiberportcanbeup-linked

to an upper level hub's port. You may use the "1/MPR" port to

up-link the hub to an upper level hub's TP port. Only one up-link

is allowed between any two hubs.

3. Plug the female end of the AC power cord into the receptacle

on the back of the Switch unit. Plug the other end into an AC

power source.

NOTE: 4000-ST/SC models will automatically power ON when

plugged in. The 8020-ST/SC models provide a ON/OFF switch

control on the back of the unit.

2-1.3 Switch Hub Cascading & Long Haul Connections

Theoretically, the switch hub breaks up the collision domain in hub

cascading so you may unlimitedly up-link the hubs. However,

in practice, the network extension (cascading levels & overall

diameter)islimitedbythetimingrequirement(time-outspecification)

of your application software and network operating system.

The sum of 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 TP, fiber cables and devices' bit-time

delay (round trip) is as follows:

100Base-TX 100Base-FX

DTE↔DTE: 100 DTE ↔DTE: 100

Cat. 5 TP Wire: 1.112/m Fiber Cable: 1.0/m

DTE FX to DTE TX: 100

100Base-TX to 100Base-FX Converter: 56

Multiple Hubs Cascading and Long-Haul Connection

3-1 Troubleshooting

Network troubleshooting requires patience and logic. Generally

speaking,thecablingandworkstationconfigurationsarethelikelyfirst

suspects; network hardware is usually last on the list. It is more likely

for an entire hub to fail instead of just a single port.

3-1.1 Cabling Problems

Networktroubleshootingrequirespatienceandlogic.ImproperCabling

is the primary cause of most non-workstation problems on Ethernet

network, particularly for 100 Base-TX and -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.

• Multi-mode fiber cable should match the switch’s fiber

transceiver. Flat telephone extension cables or Cat. 3 wires sold

at electronics stores are not the same as Cat. 5 twisted-pair

cable and will not work in 100Mbps network.

3-1.2 Workstation Problems

Mostnon-cabling problems result from improperconfiguration of the

networkinterfacecard(NIC)anditscorrespondingdriver.Thefollowing

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.

• If a workstation (workstation A) does not work and other

100Base-X ports on the hub are functioning, remove a fiber/

RJ-45 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.

3-1.3 Other Problems

OtherspecificproblemsmaybediagnosedbyusingtheLEDs,asbelow.

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/TP port:

• Faulty node or wiring connection.

For fiber: the “TX”, “RX” cables should be paired at both ends

For TP: a clicking sound should be heard when the RJ-45

plug is inserted in the STP RJ-45 jack

• 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 does not work:

If the hub does not work or is experiencing interference (e.g., your site

maybelocatednearradiostationortransmitter,etc.),tryusingshielded

twisted-pair (STP) cable instead of UTP cable.

Hub Diagnostic Test

• The switch hub performs a 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.
