3. Making LAN Connections
3.1 10/100 Copper Ports
The 10/100 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
Link distance: Up to 100 meters
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 a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
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.
