NOTE: Both rows of QSFP+ ports require that you install the 40GbE optics with the tabs facing up. NOTE: When you cable the ports, be sure not to interfere with the airflow from the small vent holes above and below the ports. Splitting QSFP+ Ports to SFP+ Ports The S5000 supports splitting a single 40GbE QSFP+ port into four 10GbE SFP+ ports using one of the supported breakout cables. For a list of supported optics, refer to the S5000 data sheet: http://www.dell.com/us/enterprise/p/force10-s-series/pd. • Configure the system to recognize the port mode change. CONFIGURATION mode stack-unit unit-number port number portmode quad - stack-unit - Enter the stack member unit identifier of the stack member to reset. The range is 0 to 11. The default is 0. - port - Enter the port number of the 40GbE port to be split. The range is 48 to 60. - portmode quad - Configure a 40GbE port to operate in 4x10GbE mode. Example of splitting a QSFP+ port to SFP+ ports stack-unit 0 port 52 portmode quad Important Points to Remember • You cannot use split ports as a stack-link to stack an S5000 unit. • The quad port must be in a default configuration before you can split it into four 10GbE SFP+ ports. When you split the port, the 40GbE port is lost in the running configuration. Be sure that the port is also removed from other L2/L3 feature configurations. • For the split-port change to take effect, you must reload the system after issuing the CLI change commands. Connecting the Stacking Ports (Optional) Before you make your stacking port connections, rack-mount the systems or insert them into a cabinet. To connect the stacking ports, insert one end of the optical cable into a configured port and insert the other end of the optical cable into a similarly configured port of the adjacent system. There are no unique stacking ports; you can configure the SFP+ and QSFP+ ports to act as stacking ports. The SFP+ ports are labeled 0 to 47. The QSFP+ ports are labeled 48 and 56 for the lower ports and 52 and 60 for the upper ports. NOTE: You can connect up to six S5000 switches in a single stack. NOTE: The S5000 system does not stack with other S-Series systems. NOTE: Stacking is not supported on 40GbE ports operating in 4x10GbE (quad) mode. NOTE: If you use three or more S5000 units in a stack, you can connect up to a maximum of eight 10GbE ports or two 40GbE ports in links between peer switches. If you use only two S5000 units in a stack, you can connect up to four 40GbE ports in links between the two switches. Important Points to Know • Data ports are configured as stacking ports in predefined stacking groups of 40GbE (four 10GbE ports or one 40GbE port). 38
