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 Networking OS places the interface in error-disabled (operationally down) state.

Transceiver in slot 1 port 50 unrecognized, putting interface in operational-
down state
The following command output displays that the interface is in error-disabled state:
