Rear panel USB ports

Lenovo ThinkSystem DS Series controllers contain a USB (Universal Serial Bus) Device interface pertaining to
the Management Controller (MC). The Device interface is accessed via a port on the controller module face plate.
This appendix describes the USB Type B port labeled CLI, which enables direct connection between a
management computer and the controller, using the command-line interface and appropriate cable.

DS Series controllers feature a USB CLI port used to cable directly to the controller and initially set IP addresses,
or perform other configuration tasks. The USB CLI port employs a mini-USB Type B form factor, and requires a
specific cable and additional support, so that a server or other computer running a Linux or Windows operating
system can recognize the controller enclosure as a connected device. Without this support, the computer might not
recognize that a new device is connected, or might not be able to communicate with it.
For Linux computers, no new driver files are needed, but a Linux configuration file must be created or modified.

Once attached to the controller module, the management computer should detect a new USB device. Using the
Emulated Serial Port interface, the DS Series controller presents a single serial port using a customer vendor ID and
