Splitting QSFP Ports to SFP+ Ports
The S4810 supports splitting a single 40G QSFP port into four 10G SFP+ ports
using one of the supported breakout cables (refer to Installing the S4810 System
or Release Notes for the S4810 System for a list of supported cables).
You must enter the stack-unit portmode command for the system to recognize
the port type change. For example:
stack-unit stack-unit port number portmode quad
• stack-unit: Enter the stack member unit identifier of the stack member to
reset. Range: 0-11
• number: Enter the port number of the 40G port to be split. Range: 0-31

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 S4810.
• Split ports S4810 unit cannot be a part of any stacked system.
• The unit number with the split ports must be the default (stack-unit 0). This
can be verified using the show system brief command. If the unit ID is
different than 0, then it must be renumbered to 0 before ports are split, by
entering in EXEC mode: stackunit id renumber 0
• The quad port must be in a default configuration before it can be split into
4x10G ports. The 40G port is lost in the running-configuration when the port
is split, so be sure the port is also removed from other L2/L3 feature
configurations.
• The system must be reloaded after issuing the CLI for the change to take
effect.

Supply Power and Power Up the System
