Twisted Pair Ports
Connector Type
Speed
Duplex Mode
58
This section applies to the twisted pair ports on the following line cards
and expansion module:
AT-SBx81GT24 Line Card
AT-SBx81GT40 Line Card
AT-SBx81GP24 Line Card
AT-SBx81XLEM/XT4 Expansion Module
AT-SBx81XLEM/GT8 Expansion Module
The ports on the line cards and expansion module have 8-pin RJ-45
connectors, except for the AT-SBx81GT40 Line Card, which have 8-pin
RJ point 5 connectors.
The ports use four pins at 10 or 100 Mbps and all eight pins at 1000 Mbps
or 10 Gbps. The pin assignments are listed in "Port Pinouts" on page 279.
The possible port speeds are listed here:
AT-SBx81GT24, AT-SBx81GT40, and AT-SBx81GP24 Line Cards
and AT-SBx81XLEM/GT8 Expansion Module - 10, 100, or 1000
Mbps
AT-SBx81XLEM/XT4 Expansion Module - 1000 Mbps or 10 Gbps
The switch can set the speeds automatically through Auto-Negotiation, the
default setting, or you can manually set the them with the AlliedWare Plus
Operating System.
Note
Twisted-pair ports have to be set to Auto-Negotiation to operate at
1000 Mbps or 10 Gbps.
The twisted-pair ports on the AT-SBx81GT24 and AT-SBx81GP24 Line
Cards and AT-SBx81XLEM/GT8 Expansion Module 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-compliant and Auto-Negotiate the duplex mode setting.
You can disable Auto-Negotiation on the ports and set the duplex mode
manually.
