Setting Up Breakout Cables

Dell OS10 Manual

Platform Information

WARNING If you are using QSFPs you must use Dell branded QSFPs! For breakout mode to work it requires physical modification of the QSFP. It is possible other vendors may make these modifications, but most of the time they do not. When I tested with Intel QSFPs it did not work.
