Rear panel USB ports
S3200/S2200 controllers contain two different USB (universal serial bus) management interfaces: a
Host
interface and a
Device
interface. Both interfaces pertain to the Management Controller (MC). The Device
interface is accessed via a port on the controller module face plate. The Host interface (USB Type
A)—reserved for future use—is accessible from the midplane-facing end of the controller module (see
Figure 11
on page 20), and its discussion is deferred.
This appendix describes the port labeled CLI (USB Type B), which enables direct connection between a
management computer and the controller, using the command-line interface and appropriate cable (see
Figure 48
).

NOTE:
In the illustration above, the sticker suggesting that you “install the USB driver before using the
port” has been removed to show the port.
S3200/S2200 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 (see
Follow the instructions accompanying the device driver topic for Microsoft Windows.
on
page 78). 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
Microsoft Windows
on page 78).
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 S3200/S2200 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
Supported host applications
). Serial
port configuration is unnecessary.
