Brocade ICX 6650 slot and Ethernet port numbering
Many CLI commands require users to enter port numbers as part of the command syntax, and many
show command outputs display port numbers. The port numbers are entered and displayed in stack-
unit/slot number/port number format. In all Brocade ICX 6650 inputs and outputs, the stack-unit number
is always 1.
The Brocade ICX 6650 contains the following slots and Ethernet ports:
• Slot 1 is located on the front of the Brocade ICX 6650 switch and contains ports 1 through 56, which
are 1/10 GbE SFP+ ports. Refer to the following figure.

• Slot 2 is located on the rear of the Brocade ICX 6650 switch and contains ports 1 through 3 on the
top row and port 4 on the bottom row. These ports are 40 GbE QSFP+ ports. Refer to the following
figure.
NOTE
The QSFP+ 40 GbE LR4 optical transceiver is supported in ports 1 and 2 only. When the module is
inserted into a stack-unit/slot number/port number combination that is not 1/2/1 or 1/2/2, the following
error message displays: “QSFP LR-4 optics not supported on port port-number.”
