3.1.3 RS232 (Console)
The port labeled “Console” is an RS232 serial port on the back side of the chassis in
SN700 and SN2410, and on the front side in SN2740 and SN100. It is used for initial configura-
tion and debugging. Upon first installation of the system, you need to connect a PC to this inter-
face and configure network parameters for remote connections. Refer to Section 2.8.1 to view the
full procedure.
3.1.4 Management
The RJ45 Ethernet ports labeled “MGT” provide access for remote management. The man-
agement ports are configured with auto-negotiation capabilities by default (100MbE to
1000GbE). The management ports’ network attributes (such as IP address) need to be pre-config
-
ured via the RS232 serial console port or by DHCP before use. Refer to Section 2.8.1 to view the
full procedure.
3.1.5 USB
The USB interface is USB 2.0 (mini USB in SN2100) compliant (USB 1.0 is not supported) and
can be used by Onyx (MLNX-OS) software to connect to an external disk for software upgrade
or file management. The connector comes in a standard USB shape.
To view the full matrix of the USB configuration options, refer to Table 4, “Management Inter-
faces, PSUs and Fans”.
In the SN2100/SN2010 systems there is only one MGT port.
Make sure you use only FCC compliant Ethernet cables.
Do not use excessive force when inserting or extracting the USB disk to and from the
connector.
