The copper ports support the following connection types and distances: 

10BASE-T:   

2-pair UTP Cat. 3,4,5 , EIA/TIA-568B 100-ohm 

100BASE-TX:  2-pair / 4-pair UTP Cat. 5, EIA/TIA-568B 100-ohm 

Link distance:  Up to 100 meters 

 

This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid 

MDI to MDI-X connection with the remote connected device automatically. No matter a straight 

through cable or crossover cable connected, the ports can sense the receiving pair automatically and 

configure self to match the rule for MDI to MDI-X connection. It simplifies the cable installation. 

 

The ports are featured with auto-negotiation function and full capability to support connection to any 

Ethernet devices. The port performs a negotiation process for the speed and duplex configuration with 

the connected device automatically when each time a link is being established. If the connected device 

is also auto-negotiation capable, both devices will come out the best configuration after negotiation 

process. If the connected device is incapable in auto-negotiation, the switch will sense the speed and 

use half duplex for the connection.
