Standard TIA/EIA 568-C-compliant
Category 6a shielded cabling.
The 10/100/1000 Mbps twisted-pair ports on the AT-SBx81GT24, AT-
SBx81GT40, and AT-SBx81GP24 Line Cards and AT-SBx81XLEM/GT8
Expansion Module are IEEE 802.3ab compliant and feature automatic
MDIX detection when operating at 10 or 100 Mbps. (Automatic MDIX
detection does not apply to 1000 Mbps or 10 Gbps.) This feature
automatically configures the ports to MDI or MDI-X depending on the
wiring configurations of the end nodes.
Ports connected to network devices that do not support automatic MDIX
detection default to MDIX.
You may disable automatic MDIX detection on the individual ports and
configure the MDI/MDI-X settings manually with the POLARITY command.
Refer to Table 43 on page 279 for the pinouts of the twisted-pair ports
when they operate at 10 or 100 Mbps in the MDI configuration and
Table 44 on page 279 for the MDI-X configuration. For the port pinouts
when they operate at 1000 Mbps or 10 Gbps, refer to Table 45 on
page 280.
