3.1.1

Data Interfaces

The data interfaces use QSFP28 connectors. The full list of interfaces per system is provided in
Table 3, "Speed and Switching
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 systems offer High Power/LR4 transceivers support (up to 3.5W) in all ports.
3.1.2

Speed

Ethernet speed must be set manually. The system's ports can be manually configured to run at
speeds ranging from 10GbE 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.
3.1.3

RS232 (Console)

The port labeled "Console"
SN700 and SN2410, and on the front side in SN100. It 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
cedure.
3.1.4

Management

The RJ45 Ethernet ports labeled "MGT"
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-
