Patch panels are generally attached in the network racks, mostly above or below the network switches. The patch panels predominantly occupy a space of 1U in the network racks. All the cables from the desktops are brought to the patch panels and they are terminated at the back side of the patch panel. (The UTP cable consists of 4 Pairs, all these 8 cables are separated at the end and punched individually behind the patch panel).
UTP Patch cords connect the individual ports in the patch panel to the individual ports in the network switch. This enables permanent connection to the switch, which is not disturbed and all adds, moves and changes are done at the patch panel level.
But why introduce a new component in the already cluttered data center? Can’t we just terminate the cables directly to the switch? Yes, it is fine to terminate the UTP cables from the desktops directly to the network switches. The set-up would still work. But a patch panel is introduced in between the network switch and the desktop cables for the following reasons:
Identification: The patch panel ports can be labeled (Location, desktop number etc) to help identify which cable from which location is getting terminated on which port of the patch panel. Now, when there is a need for testing or disconnecting a particular cable, you could easily locate them on the patch panel.
The switch is not disturbed, when small changes are being made with the network cabling. The changes can be made quickly and easily.
All the cables can be terminated on the patch panels (irrespective of whether they need to be connected to the switches or not) and they could be selectively connected to the switches by just moving the patch cables, whenever needed.
Testing/ troubleshooting: During a connection fault, Patch panels help identify whether the fault is at the switch side or at the cable (network) side. They also help in troubleshooting.
