I work for a small business in a generalized IT role. We are moving to a new location and I've got 100 Ethernet cables coming into a patch panel. The previous occupant did not leave the information on the panel to tell me which desk has which cable. I know there must be something I can attach at the desk end, and something I can plug into each of my patch panel ports to figure out which cable I am now looking at. I just don't know what that is. Please let me know what I should be looking for in the market place. The distance between desk and patch panel - I can't imagine over 60 ft. Each desk has two cables, with one as a spare. So 50 seats or so. Thanks.
