10GBASE-T/5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX Port 
10GBASE-T/5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX is a port that supports self-adaptation of five 
rates, and automatic MDI/MDIX Crossover at these five rates. 
10GBASE-T 
10GBASE-T complies with IEEE 802.3an standard, and the supported cables and cabling distances are listed 
in the following table. 10GBASE-Tport uses four pairs of wires for transmission, all of which must be connected. 
The following table shows the connection of the twisted pairs used by the 10GBASE-T port.

Meet the minimum performance 
requirements of 10GBASE-T standard. 
Strictly follow TSB-155 standard 
requirements to ensure the reliable 
application of 10GBASE-T. 
 
Note 
The maximum transmission distance  will be less than 37m (121.39 ft) when CAT6 UTP unshielded wire is 
exposed in severe condition and influenced by external crosstalk.
