EM would be less of an issue , The cable runs are there regardless and most of the em would be picked up in the ceiling vs the patch panel to switch . The issue would be mostly needing to disable and reenable ports on the switch . You would need to use a 11 patch pattern . Like port 1 on the panel would need to be port 1 on the switch . So if port 1 doesn ' t have a device connected to it , switch port 1 would need to be disabled to protect your network , you don ' t want unauthorized devices being connected . There of course are other options to this such as using a quarantined VLAN on the port that can auto switch to an authorized VLAN when an authorized devices plugs and and moves back to quarantine when it ' s done , or shuts down if something bad is happening . But it depends on your network and your needs configuration .
