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<unit-number> - Enter the stack member unit identifier of the stack member to reset.
The range is 0 to 11. The default is 0.
port <number>- 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.
Supplying Power and Powering Up the System
Supply power to the S5000 system after the chassis is mounted in a rack or cabinet.
WARNING: Installing and swapping of Unified Port or Ethernet modules must be done BEFORE
power up. If you need to replace a module, power down the system before you replace it. If you
replace a module when the system is powered up, the system does not recognize the module.
Online insertion of modules can result in a catastrophic failure.
Dell Networking recommends reinspecting your system prior to powering up. Verify that:
The equipment is properly secured to the rack.
The equipment rack is properly mounted and grounded.
The ambient temperature around the unit (which may be higher than the room temperature) is within
the limits specified for the S5000.
There is sufficient airflow around the chassis.
The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection
devices.
