Automatic MDIX
Detection
The 10/100/1000 Mbps twisted-pair ports on the AT-SBx81GT24, AT-
SBx81GT40, and AT-SBx81GP24 Line Cards 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.) 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.
Port Pinouts Refer to Table 35 on page 239 for the port pinouts of the twisted-pair ports
when they operate at 10 or 100 Mbps in the MDI configuration and
Table 36 on page 239 for the MDI-X configuration. For port pinouts when
the twisted-pair ports operate at 1000 Mbps, refer to Table 37 on
page 240.
