A cable management system for a network cabinet has first and second server equipment rails, first and second air dams, and a front cable support. The server equipment rails are mounted to a base frame of the network cabinet such that the server equipment rails extend from the base frame towards a front of the network cabinet. The air dams are mounted to the base frame of the network cabinet such that the air dams extend from the base frame towards opposing sides of the network cabinet. The front cable support has a generally U-shaped tray that is connected to the first and second server equipment rails such that the tray extends across a front of the network cabinet, transverse to the server equipment rails.
