Rev 1.6.9 Specific ports can be split by using a QSFP 1X4 breakout cable to split one 40 Gb/s port into 4 lanes (4 SFP+ connectors). These 4 lanes then go, one lane to each of the 4 SFP+ connectors. Some ports can be split into 2 10 Gb/s ports, using lanes 1 and 2 only. When a QSFP port is split into 2 10Gb/s ports then only SFP+ connectors #1 and #2 are used. Connectors #3 and #4 are left unconnected. Splitting the interface deletes all configuration on that interface. 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). • which ports can be split into 4 • which ports can be split into 2 • which ports will be unmapped due to a 1X4 split Figure 9: Port Splitting Options This port can be split into 4 10Gb/s SFP+ This port can be split into 2 10Gb/s SFP+ This port is unmapped by the neighboring split 4 port The maximum number of 10 Gb/s Ethernet ports configurable with this switch is 34.
