Since copper patch panels need to be strong enough not to flex too much as the cables are punched down
. The rolled edges on the panel sheet metal stock help to make the panels rigid. Copper patch panels should provide 24 ports in a 1U height or 48 ports in a 2U height. It's very important to make sure that the modular jacks and circuit traces on the panels are protected from debris that can short out circuits. All cable management systems must be easy to use and maintain to avoid any potential problems.
