Some major role in the 12 port patch panel

MDF main purpose is to point at the central office for the front-end information management modular equipment. The front of the information point cable (Cat5e or 6 cable) into the equipment room after the first into patch panels, patch panels will hit the line modules, patch panels and switches then connect a jumper (RJ45 interface) . Overall, the patch panel is displayport to hdmi cable  used to manage the device, 12 port patch panel for example, if there is no patch, direct access to the front of the information points to the switch, so that once the cable problems, faced to rewire . In addition, the management is also a bit confusing, multiple plug may cause damage to the switch port. MDF exist to solve this problem by replacing the jumper to achieve better management.
12 port patch panel Dosage and overall network is mainly based on the number of points or the floor (and similar floor, depending on how the system is designed diagram) points to the number of network configurations. Different buildings, different system designs, patch panels are the  Micro USB cable main differences between the devices. For example, a building only four rooms, the master device is set on the first floor, all floors between network points are entering the device, then the patch is equal to the number of the building all network points / patch panel port number (24 mouth, 48, etc.), plus got to margin; If, on the 9th floor of a building has a room, the master device is set on the fourth floor, then in order to avoid long cable, it may partakers devices are located on each floor , and there is exchange equipment. So the cat6 network cable  main distribution frame between devices on the network is equal to the number of points / patch panel port 4 layers
