The error occurs because the line card has more interfaces than the available PFEs to support them. For instance, in the case of the 6x40GE + 24x10GE MPC5E, known as the MPC5E 3D 24XGE+6XLGE in the CLI, it has a line throughput of 240 Gbps. It supports the following port combinations:
Consider the following example for context:

In the aforementioned example, the device currently contains three 40 Gb ports on PIC3 and six 10 GB ports on PIC0. If an attempt is made to activate PIC 1 or PIC 2 using the CLI command 'set chassis fpc X pic X power on,' an error message stating 'FPC slot 1 does not support this command' will be displayed on the chassis. Note - When considering powering on a PIC to support a specific port combination, it's crucial to identify the appropriate PIC for that combination. Only the respective PIC supporting the required ports should be powered on, while the remaining PICs need to be powered off.
