How handle Power budget exceeded error on Dell R630?

What can I do if I got following error message on a Dell R630:

mlx5_core 0000:82:00.0: mlx5_port_module_event:1131:(pid 2265): Port module event[error]: module 0, Cable error, Power budget exceeded

The Adpater I am using: MCX556A-EDAT

The both transceivers:

Both transceivers are using 3.5Watt max. Only plug in one transceiver works. When inserting the second I got this message.

On a Dell R740 this message is not coming and all work as expected.

Is there any limitation due to the Dell R630. Can I change something in the BIOS ?
