All of these network connections are therefore individually wired back to a central
location into what is often termed a “wiring cabinet” or “wiring closet”. Each network
connection is presented on a “patch panel” or “wiring frame”. Contained within this unit will be electrical power and the network components such as switches. Hence, to enable any given network connection it is a simple case of connecting a wire (a ‘patch lead’) between the network connection point on the wiring frame and one of
the ports on the switch. If the hub has sufficient ports then you can, of course, make
all network connections live or, you can choose to switch in only those that are required.
