The S6000 supports splitting a single 40G QSFP port into four 10G SFP+ ports using one of the supported
breakout cables (refer to the S6000 Installation Guide or the S6000 Release Notes for a list of supported
cables).
Important Points
• Splitting a 40G port into 4x10G port is supported only on a standalone unit.
• Split ports cannot be used as stack-link to stack an S6000.
• Split ports cannot be a part of any stacked system.
• Few of the Ports in S6000 are fixed 40G Ports and hence splitting is not allowed. Fixed Port nos are
(4,12,20,28,100,108,116,124)
Figure 20-24. Example of port number
• Reload is mandatory when QSFP ports are converted into 4*10G SFP+ ports using portmode quad cli
and the same for converting back quad ports to QSFP Port
