Twisted-Pair Port - Allied Telesis AT-8400 Series Reference Manual

AT-8400 Series Switch Reference Guide
Twisted-pair
Type of Connector
Port
The twisted-pair port features an 8-pin RJ-45 connector. (The port uses
four pins when operating at 10 or 100 Mbps and all eight pins when
operating at 1000 Mbps.)
Speed
The twisted-pair port can operate at 10, 100, or 1000 Mbps. The speed is
set automatically through Auto-Negotiation or you can set the speed
manually through the management software.
Duplex Mode
The twisted-pair port can operate in either half- or full-duplex mode. The
port is IEEE 802.3u-compliant and will Auto-Negotiate the duplex mode
setting. If desired, Auto-Negotiation on the port can be disabled so that
you can set the duplex mode manually through the management
software.
Maximum Distance
The twisted-pair port has a maximum operating distance of 100 meters
(328 feet).
Type of Cabling
For 10 Mbps, the port requires Category 3 or better 100 ohm shielded or
unshielded twisted-pair cabling. For 100 or 1000 Mbps operation, the
port requires Category 5 or Enhanced Category 5 (5E) 100 ohm shielded
or unshielded twisted-pair cabling.
Auto-MDI
The twisted-pair port is auto-MDI. It automatically configures itself as
either MDI or MDI-X when connected to an end node. This feature allows
you to use either a straight-through or crossover twisted-pair cable
when connecting any network device to the port.
Port Pinouts
For the pinouts of the twisted-pair port when operating at 10 or 100
Mbps in the MDI configuration, refer to Table 6 on page 32. For the
pinouts of the twisted-pair port when operating at 10 or 100 Mbps in the
MDI-X configuration, refer to Table 7 on page 32.
