Connecting to the controller CLI port
Device description
The MSA 1060/2060/2062 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 system, and additional support described herein, 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 systems, 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 using an operating system
predating 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
).
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
After the CLI cable is attached to the controller module, the management computer should detect a new 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 host previously had a terminal emulator
installed (see
). MSA 1060/2060/2062 controllers support the following applications to facilitate connection.

Preparing a Linux system 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)
You can query information about USB buses and the devices connected to them by entering a command:
