Ports
The CX310 provides ports for users to operate and configure. The ports are used to send and receive data.
The CX310 Ethernet ports are numbered in the Slot number/Subcard number/Port number format.
- Slot number: indicates the slot number of the current switch module. Its value ranges from 1 to 4, from left to right mapping to slot numbers 1E, 2X, 3X, and 4E.
- Subcard number: indicates the number of a subcard supported by switching service ports. Its value ranges from 1 to 19.
- Port number: indicates the sequence number of a port on a subcard.
For details about subcard numbers and port numbers, see Table 2-2 and Table 2-3.
For example, if the CX310 is in slot 2X, the first GE port on the upper right on the panel is numbered 10GE 2/17/16, as shown in Figure 2-5.
Table 2-2 describes the external ports on the CX310.

The serial ports include the baseboard management controller (BMC) serial port and the SYS serial port. These ports comply with RS232, and do not have an indicator.
The BMC serial port and the serial port of the converged switching plane support a baud rate of 115,200 bit/s. |

The value ranges from 1 to 16. The ports are numbered from 1 in ascending order from left to right and then from bottom to top. |
The sixteen ports are used to exchange data with an external network. Two indicators are provided for each port. The orange indicator is the data transmission status indicator, and the green indicator is the connectivity status indicator. |
Table 2-3 describes the internal ports on the CX310.

1–16 |
1 or 2 |
The ports connect to the front half-width slots 01 to 16, and map to subcard numbers from 1 to 16. |
If the CX310 is in slot 2X, the ports connected to the compute node in slot 1 are 10GE 2/1/1 and 10GE 2/1/2. |
40GE port |

18 |
1 |
The port is used to connect switch modules in the 1E and 4E slots or in the 2X and 3X slots. |
If the CX310 is in slot 2X, the port is numbered 40GE 2/18/1. |
GE port |
2 |
19 |
1 or 2 |
Two GE ports connect to two MM910s respectively. They are used to communicate with eth0 and eth2 in the MM910. |
If the CX310 is in slot 2X, the ports are numbered GE 2/19/1 and GE 2/19/2. |
