FCC Regulations
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense.
Canadian Regulations
This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on
the radio interference regulations 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 class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.

Jabber : Illuminated red LED indicates that unit is disabled.
Collision: Flashing or illuminated red LED
indicates collisions.
Transmit: Flashing or illuminated green LED
indicates packet(s) are being
transmitted.
Receive: Flashing or illuminated green LED
indicates packet(s) are being received.
Link Illuminated green LED indicates the
unit is receiving link pulses from a
compliant device.
Power: Illuminated green LED indicates
connection to external power.
FAULT ISOLATION and CORRECTION
If the transceiver fails, determine the answers to the following questions:
1. Is the power LED on the transceiver illuminated?
NO
• Verify that the transceiver is installed properly in the AUI port and
that the device is powered ON.
• Contact Technical Support at (800) 260-1312 or at (800) LAN-
WANS.
YES
• Proceed to step 2.
2. Is the Link LED illuminated?
NO
• Check the fiber cables for proper connection. (If possible, try a
different pair of fiber cables.)
• Contact Technical Support at (800) 260-1312 or at (800) LAN-
WANS.
YES
• Proceed to step 3.
3. Is the fiber cable connected properly?
NO
• Verify that TX and RX cables on transceiver are connected to RX
and TX ports, respectively, on each device.
• Contact Technical Support at (800) 260-1312 or at (800) LAN-
WANS.
YES
• Contact Technical Support at (800) 260-1312 or at (800) LAN-
