Ports

This topic describes the features, numbering rules, names, types, and quantities of the CX910 ports.

The CX910 provides ports for users to operate and configure. The ports are used to send and receive data.

The CX910 ports are numbered in 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 service ports. The value ranges from 1 to 19.
  • Port number: indicates the sequence number of a port on a subcard.

For details about the value options, see Figure 2-5, Table 2-2, and Table 2-4.

For example, if the CX910 is in slot 2X, the first GE optical port on the upper right of the panel is numbered GE 2/17/4, as shown in Figure 2-5.

The serial ports include the baseboard management controller (BMC) serial port and the SYS serial port. The ports comply with RS232, and the port type is RJ45. No indicator is available.

  • BMC serial port: The port is used to log in to the BMC command-line interface (CLI).
  • SYS serial port: This port is used for managing, maintaining, and commissioning the 10GE switching plane.

The BMC serial port and serial ports of the and 10GE switching plane support the baud rate of 115,200 bit/s.

The value ranges from 1 to 4.

The onboard GE switching plane provides four GE ports for server control and management.

Each port has two indicators. The orange one is a data transmission status indicator, and the green one is a connection status indicator.

The value ranges from 1 to 16.

The 10GE switching plane provides sixteen 10GE ports for external network switching.

Each port has two indicators. The orange one is a 10GE optical port data transmission status indicator, and the green one is a 10GE optical port connection status indicator.

1 to 16

The value is 1.

The ports connect to the front half-width slots 1 to 16, and map to subcard numbers from 1 to 16. The ports are reserved and cannot be used currently.

If the CX910 is in slot 2X, the port connected to the compute node in slot 1 is numbered GE 2/1/1.

GE port

2

19

The value ranges from 1 to 2.

Two GE ports connect to two MM910s respectively. They are used to communicate with the eth0 and eth2 in the internal MM910.

The two ports can communicate with the MM910s only when the switch module is in slot 2X or 3X.

If the CX910 is in slot 2X, the ports are numbered GE 2/19/1 and GE 2/19/2.

10GE port

-

1

18

The value is 1.

The port is used for interconnecting onboard GE switching planes of switch modules in slots 1E and 4E, or in slots 2X and 3X.

If the CX910 is in slot 2X, the port is numbered 10GE 2/18/1.

1–16

The value is 1 or 2, or ranges from 1 to 3.

The port connects to half-width, front slots 1 to 16. Half-width slots 1 to 8 each connects to three 10GE ports. The port numbers are from 1 to 3. Half-width slots 9 to 16 each connects to two 10GE ports. The ports are numbered 1 and 2.

If the CX910 is in slot 2X, the ports connected to the compute node in slot 1 are numbered 10GE 2/1/1, 10GE 2/1/2, and 10GE 2/1/3.
