Twisted Pair Ports - Allied Telesis AT-8016F/MT Installation Manual

Maximum Distance - Each fiber optic port has a maximum operating
distance of 2 kilometers (1.25 miles) when operating in full-duplex mode
and 412 meters (1,360 feet) when operating in half-duplex mode.
Type of Cabling - The ports can use either 50/125 or 62.5/125 micron
multimode fiber optic cable.

Description
The above Fast Ethernet switches feature 24 twisted pair ports.
Type of Connector - All twisted pair ports feature 8-pin RJ-45 connectors.
(For the port pinouts, refer to RJ-45 Twisted Pair Port Pinouts on page
85 in Appendix A, Technical Specifications.
Speed - The ports are 10Base-T and 100Base-TX compliant and are
capable of both 10 megabits per second (Mbps) and 100 Mbps speeds.
You can set the port speed manually or, since the ports are IEEE 802.3u
Auto-Negotiation compliant, you can let the switch set each port's
speed automatically. With Auto-Negotiation, the switch automatically
matches the highest possible common speed between each switch port
and each end node. For example, if an end node is capable of only 10
Mbps, the switch sets the port connected to the end node to 10 Mbps.
Duplex Mode - Each twisted pair port on the switch can operate in either
half- or full-duplex mode. The twisted pair ports are IEEE 802.3u-
compliant and will Auto-Negotiate the duplex mode setting. If the end
node connected to a twisted pair port on the switch is capable of full-
duplex operation, the switch sets the twisted pair port to full-duplex. If
the end node is capable of only half-duplex, the port is set to half-
duplex.
Note
Do not use single-mode fiber optic cable with these ports.

Note
Auto-Negotiation is activated as the default on all twisted pair ports
on the switch. To deactivate Auto-Negotiation and set the speeds
manually, refer to the AT-S39 Management Software User's
Guide.
