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
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 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 port is 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 port 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 set port
configuration to one of non-auto (forced) operating modes and specify speed and duplex mode which match the
configuration used by the connected device.
Two methods for setting copper port configuration are as follows:

2.6 Making Fiber Connection
The fiber (FX) port is equipped with two SFP slots to support dual-speed fiber connectivity. One slot, labeled
GE_SFP is used for installing Gigabit Ethernet SFP transceiver for 1000BASE-X connection. The other,
labeled FE_SFP is used for installing Fast Ethernet SFP transceiver for 100BASE-FX connection.
