Why some 100M switches have all and others have only half connections in every RJ45 socket. Op paper it seems they have same specs.

I know that only 2 pairs are required. Internally both only use 2 pairs from socket. D-Link switch internally has unused pairs bridged (soldered together). -What is the difference?

Examples are in two photos:

D-Link DES-1008D
Canyon CN-D08P
