A telecommunications panel and associated system are disclosed. In one example, the panel includes a panel housing having a first side and a second side, one or more data connectors on the first side, and a power input signal connector on the first side. The panel includes one or more combined power output and data signal connectors on the second side, each of the combined power output and data signal connectors configured to electrically connect to a twisted pair cable and including a plurality of twisted pairs each having first and second wire contacts. The one or more twisted pairs are configured to carry a power signal as a direct current voltage difference between the first and second wire contacts, and the remaining twisted pairs from the plurality of twisted pairs are configured to carry differential data signals. The telecommunications panel is configured to selectably allow pairs of the remaining twisted pairs from the plurality of twisted pairs to cooperate to carry a power signal.
