This section describes the four twisted pair ports.
The twisted-pair ports have 8-pin RJ-45 connectors. The ports use four
pins at 10 or 100 Mbps and all eight pins at 1000 Mbps. The pin
assignments are listed in Table 25 on page 114 and Table 26 on
page 114.
The port speeds of the twisted pair ports are listed here:
AT-IE200-6FT and AT-IE200-6FP Switches - 10 or 100Mbps
AT-IE200-6GT and AT-IE200-6GP Switches - 10, 100, or
1000Mbps
The switches can set the speeds automatically with Auto-Negotiation, the
default setting, or you can manually set the speeds with the AlliedWare
Plus operating system.
The twisted-pair ports can operate in either half- or full-duplex mode at 10
or 100 Mbps. Ports operating at 1000 Mbps can only operate in full-duplex
mode. The twisted-pair ports are IEEE 802.3u Auto-Negotiation compliant.
The switch can set the duplex modes automatically or you can disable
Auto-Negotiation and set the duplex modes manually.
Speed and duplex mode settings can be set independently of each other
on the ports. For example, the speed of a port can be configured manually
while its duplex mode is established through Auto-Negotiation.
Note
Switch ports connected to 10 or 100 Mbps end nodes that do not
support Auto-Negotiation should not use Auto-Negotiation to set
their speed and duplex mode settings, because duplex mode
mismatches might occur. You should disable Auto-Negotiation and
set the speed and duplex mode settings manually with the
AlliedWare Plus operating system.
The ports have a maximum operating distance of 100 meters (328 feet).
