RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio-frequency energy, and

if not installed and used properly, that is, in strict accordance with the

manufacturer’s instructions, may cause interference to radio communication.

It has been tested and found to comply with the limits for a Class A

computing device in accordance with the specifications in Subpart B of Part

15 of FCC rules, which are designed to provide reasonable protection

against such interference when the equipment is operated in a commercial

environment. Operation of this equipment in a residential area is likely to

cause interference, in which case the user at his own expense will be

required to take whatever measures may be necessary to correct the

interference.

Changes or modifications not expressly approved by the party responsible

for compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise

emission from digital apparatus set out in the Radio Interference Regulation

of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques

dépassant les limites applicables aux appareils numériques de la classe A

prescrites dans le Règlement sur le brouillage radioélectrique publié par le

Industrie Canada.

Introduction

The non-latching Fiber Optic A/B Switch is a full-duplex,

optical 2 port switch. It can be used to connect one

workstation to two different networks (one at a time) or to

other remote devices. A front panel rotary style knob

allows the user to select which of two ports (A or B) is

connected to the C port on the switch. The switch operates

using a unique all-optical micro-mirror movement. When

you turn the rotary knob on the front of the switch to select

a network, the internal micro-mirror movement redirects

the optical beam from one network port to the other

network port by rotating a miniature mirror. This

technique eliminates the need to convert optical signals to

electronic signals to for switching and it is therefore

transparent to data rates and protocols.

This switch is perfectly suited for use as a fall-back switch

when a pre-determined connection is desired in the event

of a power failure. You should use a latching fiber optic

switch like Model SW1002A for applications requiring a

switch that maintains the selected connection during the

loss of AC power. Latching switches use power only for

switching to the selected connection. No power is required

to pass data through the switches.

Installation

Place the switch in a convenient stable location and

connect the power supply unit to a reliable source of AC

power that meets the requirements shown in the

Specifications section of this manual.

This switch is ideal for use in fall-back applications

where a pre-determined connection is desirable in the

event of a power failure. Connect the two fiber leads

from the device to be shared to the switch port labeled C.

Connect the A port to the network or device to which you

want to be connected if power is lost. Connect the

remaining network or device to port B of the switch.

Your installation of this switch is now complete.

Troubleshooting

If the Fiber Optic A/B Switch fails to operate, check the

following before calling for technical support.

1. Ensure that the power supply connected to a power

source and to the switch.

2. Check the fiber optic connectors for proper

connections to the correct ports of the switch.

3. Operate the switch knob to verify that it’s tightly

secured to the switch shaft and does not spin loosely.

4. Verify the integrity of the fiber optic leads by

replacing a suspect lead with a spare.
