FCC AND IC STATEMENTS
FEDERAL COMMUNICATIONS COMMISSION
AND
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.

CHAPTER 2: Introduction
2. Introduction
The AUI to 10BASE-FL Transceiver
connects an AUI interface of an Ethernet
device (such as a LAN card installed in a
PC, or a bridge, router, hub, or repeater)
to the fiberoptic cabling of a 10BASE-FL
network. The transceiver complies with the
IEEE 802.3 10BASE-FL specification.
The transceiver features two tests: A
selectable SQE test allows SQE (heartbeat)
to be disabled when used with a hub or
repeater. When SQE test is enabled, it
sends a heartbeat signal to the attached
Ethernet card, bridge, or router.
A link integrity test automatically checks
fiber cables.

3. Installation
3.1 Setting the 4-Position DIP Switch
Position Switch Name Description
1 SQE When the transceiver is attached
(Signal Quality to a LAN card, bridge, or router,
Error) position 1 should be ON (DOWN).
When the transceiver is attached
to a hub or repeater, position 1
should be OFF (UP).
NOTE
The default switch setting for the SQE test
is OFF (UP).
2 LN ALT If the TX or RX fiberoptic cable
(Link Alert) is not connected properly or is
defective, the Link LED will blink
when switch-position 2 is ON
(DOWN).
When position 2 is OFF (UP), the
Link Alert is disabled.

9
Position Switch Name Description
3 LNK (Link) If a good connection has been
established on the RX fiberoptic
cable, the Link LED will remain
steadily ON when switch-position
3 is ON (DOWN).
When position 3 is OFF (UP), the
Link LED is disabled.
4 FD When position 4 is ON (DOWN),
(Full Duplex) the network can operate in full
duplex mode.
When position 4 is OFF (UP), the
network can only operate in half-
duplex mode.
3.2 Installing the Transceiver
1. Turn the power to the network
device off.
CHAPTER 3: Installation

AUI TO 10BASE-FL TRANSCEIVER
2. Plug the AUI to 10BASE-FL
Transceiver’s DB15 male connector
into a DB15 female AUI connector
on an Ethernet device as shown in
Figures 3-1 and 3-2.
3. If the port has a slide latch, slide it
until the mounting posts on the
transceiver lock into place.
4. Plug the transceiver’s two female ST
connectors into the male ST
connectors of a full duplex fiberoptic
segment.
NOTE
The transceiver supports 50/125-,
62.5/125-, 80/125-, or 100/140-µm duplex
fiberoptic cable.
5. Turn the power to the network
device on.

4. Troubleshooting
4.1 Calling Black Box
If you determine that your AUI to
10BASE-FL Transceiver is malfunctioning,
do not attempt to alter or repair the unit.
It contains no user-serviceable parts.
Contact Black Box at 724-746-5500.
Before you do, make a record of the
history of the problem. We will be able to
provide more efficient and accurate
assistance if you have a complete
description, including:
• the nature and duration of the
problem.
• when the problem occurs.

15
• the components involved in the
problem.
• any particular application that, when
used, appears to create the problem
or make it worse.
4.2 Shipping and Packaging
If you need to transport or ship your AUI
to 10BASE-FL Transceiver:
• Package it carefully. We recommend
that you use the original container.
• If you are shipping the transceiver for
repair, make sure you include
everything that came in the original
package. Before you ship, contact
Black Box to get a Return
Authorization (RA) number.
