3.1.1
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 5.
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/SX1700 ports 1,3,33,35
• SX1024/SX1400-ports 50,52,54,56,58,60
• SX1012- all ports
3.1.2
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.
56GbE is upgradable via a software license.
