Splitting the Data Stream Using Breakout (Fanout) Cables

Specific ports can be split by using a QSFP 1X4 breakout cable to split one 40 GbE port into 4
lanes (4 SFP+ connectors 10GbE each). These 4 lanes then go, one lane to each of the 4 SFP+
connectors.

This port can be split into 4 10Gb/s SFP+
This port is unmapped according to the Port Splitting Table
The maximum 10 Gb/s Ethernet ports configurable with this
switch is 64.
When using a port to split a data stream into 4-10Gb/s data streams (four lanes) one of the other
ports on the switch will be disabled (unmapped). When using this feature you MUST go into the
MLNX-OS® chassis management system and reconfigure the individual ports to split -4. See the
MLNX-OS® Software Command Reference Guide for instructions on port configuration.
