Port and Cable Assignments
RJ-45 Port Description
RJ-45 station ports (MDI-X) can be attached to any
devices which use a standard network interface (e.g., a workstation, server, bridge or
router). Similar networking devices (e.g., another switch or hub) can be cascaded by
connecting any of the RJ-45 station ports on the switch to a daisy-chain port (MDI) on
the other device. Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP)
cable for RJ-45 connections: 100
W
Category 3, 4 or 5 cable for 10 Mbps connections
or 100
W
Category 5 cable for 100 Mbps connections. Also be sure that the length of
any twisted-pair connection does not exceed 100 meters (328 feet).

AUI Port Description
The AUI Port provides a media independent interface that can
be attached to a thin Ethernet backbone (10BASE2), a thick
Ethernet backbone (10BASE5), or to remote device using fiber
optic cable (10BASE-F). Note that when using this port, you
must first attach a transceiver (MAU) designed to interface
with the selected media type, and then attach the cable to the
transceiver.
EMI Certification
FCC Class A (USA)
Warning: This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may cause
interference to radio communications. It has been tested and found to comply with the
limits for a Class A digital device pursuant to Subpart B 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 are required to correct the interference.
You may use unshielded twisted-pair (UTP) for RJ-45 connections - Category 3 or
greater for 10 Mbps connections, and Category 5 for 100 Mbps connections.
Class A (Canada Department of Communications)
This digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus as set out in the interference-causing equipment standard entitled
"Digital Apparatus", ICES-003 of the Department of Communications.
Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux
appareils numériques de Classe A prescrites dans la norme sur le matériel brouilleur:
"Appareils Numérques", NMB-003 édictée par le ministère des Communications.
