226 QXS G2 Hardware Installation and Maintenance Guide
The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 system 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 RAID chassis 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 also Setting Parameters for Device Driver on page 229.
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 on page 227.
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 QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424,
and QXS-G2-484 system 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 on page 226. 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 on
page 227.
Supported Host Applications
QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 system controllers support
the following applications to facilitate connection.
Command-line Interface
Once the management computer detects connection to the USB-capable device, the Management
Controller awaits input of characters from the host computer via the command-line. To see the
command-line prompt, you must press Enter. The MC provides direct access to the CLI.
