Non Dell-Qualified Transceivers
The system supports Dell-qualified transceivers and only some of the non Dell-qualified transceivers.
If the system displays an error message similar to the following, the transceiver is not Dell-qualified. The Dell EMC Networking OS places
the interface in error-disabled (operationally down) state.

Splitting 100G Ports
The platform supports splitting a single 100G QSFP 28 port into any of the following ports:
• Two 50G ports
• Four 25G ports
• One 40G port
• Four 10G ports
NOTE:
You can use the supported breakout cables (for a list of supported cables, refer to the Installation Guide or the
Release Notes).
To split a single 100G port into 50G, 25G, 40G, and 10G ports, use the following commands:
