2.9 Making UTP Connections
The 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T:
2-pair UTP Cat. 3, 4, 5 , EIA/TIA-568B 100-ohm
100BASE-TX:
2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T:
4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance:
Up to 100 meters for all above
Auto MDI/MDI-X Function
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 if a straight through cable or
crossover cable is connected, the ports can sense the receiving pair automatically and configure itself to match
the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with the 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 each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out with the best configuration after the negotiation process.
If the connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for
the connection.
Port Configuration Management
For making proper connection to an auto-negotiation incapable device, it is suggested to use port control
function via the software management to set forced mode and specify the speed and duplex mode which match
the configuration used by the connected device.
