2.1 Functions
This topic describes the functions, protocols, and ports of the CX320 switch module (CX320).
The CX320 is a switching control unit that provides data switching functionality for compute
node slots in the system and centrally provides service and management ports to connect to
external devices.
The CX320 is installed in a rear slot of an E9000 chassis and are connected to compute nodes,
storage nodes, and management modules through the E9000 midplane. It exchanges data and
control packets in the E9000 chassis and provides high-speed data transmission.

This topic describes the features, numbering rules, names, types, and quantity of the CX320
ports.
The CX320 provides ports for users to operate and configure. The ports are used to send and
receive data.
The CX320 Ethernet ports are numbered in the Slot number/Subcard number/Port number
format.
lSlot number indicates the slot number of the current switch module. The value ranges
from 1 to 4, mapping to slot numbers 1E, 2X, 3X, and 4E.
lSubcard number indicates the number of a subcard with ports. The value ranges from 1
to 22. For details, see Table 2-2, Table 2-3, and Table 2-4.
lPort number indicates the serial number of the port on the subcard. For details, see Table
2-2, Table 2-3, and Table 2-4.
For example, if the CX320 is in slot 2X, the first optical Ethernet port on the upper right of
the panel is numbered 40GE 2/20/2, as shown in Figure 2-9.
used to connect to the
BMC or converged
switching plane. During
the BMC startup, the
serial port is used by the
BMC. In other cases, the
serial port is used by the
10GE converged
switching plane by
default, and can be
switched to the BMC
over SOL.
NOTE
On the CLI, the serial port
corresponds to the
following options:
l bmccom: serial port
connecting to the
BMC.
l fabriccom: serial port
connecting to the
converged switching
plane.
The baud rate is 115200
bit/s when the serial port
is connected to the BMC
or converged switching
plane.

Ethernet port number is
10GE x/21/1, and the
first FC port number is
FC x/21/1 (x indicates
the switch module slot,
and 21 indicates PIC slot
1.) The MX517 ports are
Ethernet ports by
default. To convert them
to FC ports, see the portmode fc command in
