Connecting to the controller CLI port

Device description

The MSA 2050 controllers feature a command-line interface port used to cable directly to the controller and initially set
IP addresses, or perform other configuration tasks. This port employs a mini-USB Type B form factor, requiring a cable
that is supplied with the controller, 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. The USB
device driver is implemented using the abstract control model (ACM) to ensure broad support.
For Linux computers, no new driver files are needed, but depending on the version of operating system, a Linux
configuration file may need to be created or modified.
For Windows computers, if you are not using Windows 10/Server 2016, the Windows USB device driver must be
downloaded from the HPE website, and installed on the computer that will be cabled directly to the controller
command-line interface port (see also www.hpe.com/support/downloads).
NOTE: Directly cabling to the CLI port is an out-of-band connection because it communicates outside the data paths
used to transfer information from a computer or network to the controller enclosure.

Emulated serial port

Once attached to the controller module as shown in
USB device. Using the Emulated Serial Port interface, the controller presents a single serial port using a vendor ID and
product ID. Effective presentation of the emulated serial port assumes the management controller previously had a
terminal emulator installed (see

Preparing a Linux computer for cabling to the CLI port

You can determine if the operating system recognizes the USB (ACM) device by entering a command:
cat /proc/devices/ |grep -i "ttyACM"
If a device driver is discovered, the output will display:
ttyACM (and a device number)
