3 Interfaces
3.1

Supported Interfaces

The systems support the following interfaces:
• Data interfaces - InfiniBand and Ethernet
• 100/1000 MbE RJ45 management interface(s)
• USB port
• RS232 Console port
• I2C interface
• Reset button
• Status and Port LEDs
In order to review the full configuration options matrix, refer to Table 4, "Management Interfaces
and FRUs".
3.2

Data Interfaces

The data interfaces use QSFP+ and/or SFP+ connectors. The full list of interfaces per system is
provided in Table 3, "Speed and Switching Capabilities," on page 10.
• Each QSFP+ port can be connected with QSFP+ cable or connector for 40/56Gb/s, or
10Gb/s when connecting through Mellanox QSFP+ to SFP+ (QSA) adapters.
The systems offer LR4 transceivers support in the following ports:
• SX1036 - ports 1,3,33,35
• SX1024/SX1400 - ports 50,52,54,56,58,60
• SX1012 - all ports

3.2.1 Speed

Ethernet speed must be set manually. The SFP+ ports can be manually configured to run at
speeds ranging from 1GbE to 10 GbE. The QSFP+ ports can be manually configured to run at
speeds ranging from 1GbE to 56 GbE. To change the port speed configuration use the command
"speed" under interface configuration mode. Refer to MLNX-OS user manual for instructions on
port speed re-configuration.
Rev 1.4
56GbE is upgradable via a software license.
