3.2.2 RS232 (Console)
The port labeled “Console” is an RS232 serial port used for initial configuration and
debugging. Upon first installation of the system, you need to connect a PC to this interface and
configure network parameters for remote connections. Refer to Section 2.9.1 to view the full pro-
cedure.
3.2.3 Management
The RJ45 Ethernet port labeled “MGT” provides access for remote management. The man-
agement port is configured with auto-negotiation capabilities by default (100MbE to 1000GbE).
The management port network attributes (such as IP Address) need to be pre-configured via the
RS232 console port before using the port. Refer to Section 2.9.1 to view the full procedure.
3.2.4 USB
The USB interface is USB 2.0 compliant and can be used by MLNX-OS software to connect to
an external disk for software upgrade or file management. The USB connector comes with either
regular or mini USB shapes.
To view the full matrix of the USB configuration options, refer to Table 4, “Management Inter-
faces and FRUs”.
3.2.5 I2C
The I2C connector is located either on the power supply side (banana connector), or on the front
side (RJ45 connector).
Make sure you use only FCC compliant Ethernet cables.
USB 1.0 is not supported.
Do NOT use excessive force when inserting or extracting the USB disk from the con-
nector.
The I2C interface is used for debugging and is intended for Mellanox debug person-
nel only.
