Poppy addresses do not come to the optical port on D-Link des 1210?

Question

network hardware

Good afternoon, we are armed with a D-Link des 1210 (10 port) and the problem is that there are no poppy addresses on the optical ports, but there is access and poppies come to the copper ports in the same place. The switch itself does not ping from outside, but I repeat, users have access.

Answer 1

or there is no vlan, or the ACL needs to be edited
