Radio frequency interference statement
This equipment generates, uses and can radiate frequency energy and if not installed and used
properly, that is in strict accordance with the manufacturers 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 J of part 15 of FCC rules, which are designed
to provide reasonable protection against such interference when 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 required to
correct the interference.

1.2 Product description
RS
Fast Ethernet Media Converters offer a compact, cost-effective way to convert and transmit data
among twisted pair, and fibre network cabling environments. They allow the use of fibre media with
full-duplex devices such as Fast Ethernet switching hubs, and may sometimes be used with shared
(half-duplex) fast ethernet segments as well.
