C9900-E320 with 2 Ethernet and USB 3.0 interfaces
With the C9900-E320 ordering option, your device is equipped ex factory with two additional Ethernet interfaces and two additional USB 3.0 interfaces in the front.
Ethernet interfaces
The two additional Ethernet ports enable the connection of appropriate network components with data rates of 100/1000 Mbit/s in accordance with the Ethernet standards 100Base-T and 1000Base-T. The required speed is selected automatically.
The RJ45 connection technology with twisted-pair cables is used. The maximum length of the cable connection is 100 m. The Ethernet ports are not switched. They are suitable for cycle times <= 1 ms and for distributed clock applications in EtherCAT.
The Intel® i210 (MAC/PHY) is used as controller for both ports.

The LEDs of the LAN interfaces indicate the activity and the data transmission rate (Mbit/s). The LED shown completely green indicates whether the interface is connected to a network. If this is the case, the LED lights up green. The LED flashes when data transmission is in progress on the interface.
The green/orange LED shown indicates the data transmission rate. If the speed is 100 Mbit/s the LED is orange, at 1000 Mbit/s it is green.
USB interfaces
The two additional USB 3.0 interfaces are used to connect peripheral devices with USB ports.
