Cisco assigns the copper feature to ports 0–3 on A901-4C-F-D and A901-4C-FT-D. The SFP upgrade is a different selection. Check the chassis and existing port state so the order addresses the actual missing capability.
The equals-suffix code is listed as the paper form; an L-prefixed electronic alternative is separately identified. Specify the required form and request evidence that the proposed entitlement can be used on the intended installation. Do not treat shipping documentation as proof that a license has been activated.
Provide the router PID, software release, existing license inventory and port requirement. Verify usable license state against the matching Cisco table. Additional cables, chassis equipment and support arrangements are separate procurement items.
