A slotted duct cable management system. Patch Panels The servers in your racks must be connected to a network switch (or hub) to send and receive network traffic. If you have multiple rows of racks, it can be difficult to route all of the cables to a single high-capacity "core switch," due to distance and physical barriers. Such logistical problems also add to the cost of installing a new server, as you must run a new cable to the switch for each new server. One solution to this problem is to install multiple smaller switches in each rack or row of racks, but this can get quite expensive and adds to the complexity of your network.
