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.

Figure 105 USB device connection—CLI port
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.
“Setting parameters for the device driver” (page 155)
. For Windows computers a special device driver file,
gserial.inf
, must be downloaded from a CD or web site, and installed on the computer that will be cabled
directly to the controller’s CLI port. See also
“Microsoft Windows” (page 154)
.
Emulated serial port
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
product ID
. Effective presentation of the emulated serial port assumes the management computer previously had
terminal emulator installed. See also
“Supported host applications” (page 154)
. Serial port configuration is
unnecessary.
IMPORTANT:
Certain operating systems require a device driver or special mode of operation to enable proper
functioning of the USB CLI port. See also
“Device driver/special operation mode” (page 154)
