FCC STATEMENT
FEDERAL COMMUNICATIONS COMMISSION
INDUSTRY CANADA
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.

Chapter 2: Introduction
Introduction
The non-latching Fiber Optic A/OFF/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 “COMMON” (C) port on the switch.
This rack mount switch also includes an OFF position that
inhibits the connection of the C port to either the A or B
port. 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.
The loss or removal of power will force the switch to “fall
back” to the OFF position for security purposes.

Chapter 3: Installation
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 no connection is desirable in the event of a power
failure. Connect the two fiber leads from the device to be
shared to the common switch port labeled C. Connect the
B port to the network or device to which you want to be
connected when B is selected. Connect the remaining
network or device to the A port of the switch.
Your installation of this switch is now complete.
Chapter 4: Troubleshooting
Troubleshooting
If the Fiber Optic A/OFF/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.
