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 the Canadian Department of Communications.
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 ministère des
Communications du Canada.

2. Introduction
The 2-1 FiberSwitch is a manual switching device that enables a fiber-based network resource to be
alternately connected to two separate 10/100Mbps multimode 1300nm fiber optic segments. It can be used,
for example, to attach a workstation to different LAN segments, to manually engage backup resources,
reroute traffic, or physically isolate selectedlinks. With its integral fiber optic transceivers, the FiberSwitch
can also serve as a common repeater for increasing transmission distances beyond 2000 meters.
NOTE
Ensure that any applicable repeater rules are followed when configuring networks with the 2-1
FiberSwitch.
The 2-1 FiberSwitch is available in two models for cable segments using ST or SC style fiber connectors.
Supported network protocols include ATM, Fast Ethernet 100 Base-FX and FDDI. A traditional rotary
style switch with LED indicators is used to select and confirm the desired segment pairing.

3. Installation & Operation
The 2-1FiberSwitch is to be used only with the 5.0 Volt DC power supply provided with the unit. (Condor
Model DSA-0151D-05). This power supply satisfies the applicable UL safety standard 60950 that requires
isolation from the AC power source as well as proper grounding. To install the 2-1 FiberSwitch, simply
insert the small barrel connector from the DC supply into the mating receptacle on the rear panel and then
connect the power supply to AC power using the provided cord.
There are three multimode fiber duplex connectors on the rear panel of the 2-1 FiberSwitch labeled as
follows: [TXA RXA], [TXB RXB], and [TXC RXC]. The connector types will be either ST or SC style
depending on the particular model purchased. [TXC RXC] is always used for the common device that will
be alternately attached to either the AA@or AB@segments. The knob on the front panel is used to select
which of these two segments, A or B, will be connected to C.
NOTE
In a duplex fiber networking system, one element is used for transmitting data and the other for
receiving data. Make sure that the element carrying data transmitted FROM the remote device TO
the FiberSwitch is connected to the ARX@side of each duplex connector. The other element would
then connect to the ATX@side of the duplex connector.
