Connect USB cable to CLI port on controller face plate
Quantum QXS Storage 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 new 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 Linux
). For Windows computers a special device driver file,
gserial.inf
, must be
downloaded and installed on the computer that will be cabled directly to the controller’s CLI port (see
Microsoft Windows
).
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 Storage 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.
Caution:
Certain operating systems require a device driver or special mode of operation to enable
proper functioning of the USB CLI port (see Device Driver/Special Operation Mode
).
Supported Host Applications
QXS Storage controllers support the following applications to facilitate connection.
