Automatic MDIX
Detection
The 10/100/1000Mbps twisted-pair ports are IEEE 802.3ab compliant.
They feature automatic MDIX detection when operating at 10 or 100Mbps.
(Automatic MDIX detection does not apply to 1000Mbps.) The switch
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 can disable automatic MDIX detection on the individual ports and
configure the MDI/MDI-X settings manually with the POLARITY command.
Refer to Table 18 on page 92 for the port pinouts of the twisted pair ports.
LEDs
The twisted pair ports on the AT-GS980M/52 Switch have two LEDs. The
LEDs are shown in Figure 4.

The states of the port LEDs are described in Table 2.
