4 Interfaces
4.1 Supported Interfaces
The systems support the following interfaces:
• Data interfaces - Ethernet
• 100/1000 MbE RJ45 management interface(s)
• USB port
• RS232 Console port
• Reset button
• Status and Port LEDs
In order to review the full configuration options matrix, refer to Table 4, “Management Interfaces
and FRUs”.
4.1.1 Data Interfaces
The data interfaces use QSFP28 connectors. The full list of interfaces per system is provided in
Table 3, “Speed and Switching Capabilities”.
Each QSFP28 port can be connected with a QSFP28 cable or connector for 25/40/50/56/100GbE,
or 1/10/25GbE when connecting through Mellanox QSFP28 to SFP28 (QSA) adapters, hybrid or
split cables.
The system offers High Power/LR4 transceivers support in all ports.
4.1.2 Speed
Ethernet speed must be set manually. The system’s ports can be manually configured to run at
speeds ranging from 1GbE to 100GbE (for more details, see
“Specifications” ). To change the
port speed configuration, use the command “speed” under interface configuration mode. Refer to
the MLNX-OS user manual for instructions on port speed re-configuration.
4.1.3 RS232 (Console)
The port labeled “Console” is an RS232 serial port on the back side of the chassis that is
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 2.7.1 to view the full procedure.
4.1.4 Management
The two RJ45 Ethernet ports labeled “MGT” provide access for remote management. The
management 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-
