Cabinet according to the functional division, can be divided into many kinds of cabinets, such as network cabinets, server cabinets, etc. , cabinets and more used in the computer industry, however, will give inside, have what configuration, I believe you also is not very understanding, probably understand just stay on the cabinet framework, then, let us detailed understanding, inside the cabinet.
fiber distribution frame
fiber distribution frame is a 19 inches wide with some square hole in the metal box, used for placing and protection has been stripped off the shell, bare outside in the optical fiber. Network center outside after entering the cabinet, optical fiber is not directly on the switch, but on the optical fiber distribution frame, again by fiber optic jumper wire is connected to the exchange of optical fiber network switch ports, as shown in figure 2. Just a bunch of glass fiber to fiber, which is very fragile, if pick up on the switch directly, although also can work normally, but not casual jumper, otherwise very easy to be broken fiber.
network switch network switch is used for data exchange network device, from all directions of optical fiber and cable are connected to their port. Switches, network center of switches, in particular, is a network of 'lifeline', it is very important for the reliability and safety, so the center of the network switches must be installed in a closed, fan ark, to switch to provide safe and reliable physical environment.
network firewall network firewall is to install security barrier between internal network and external network, firewall software and hardware. Network center is the hardware firewall generally used, its appearance is similar with the router.
twisted-pair cable distribution frame
now network basically all use super five class level above the twisted-pair implementation of structured cabling, so there will be a lot of twisted pair.
router router to work in the OSI ( The Open System Interconnection, Open System Interconnection) Seven layer model of the third layer, is responsible for addressing and forwarding layer 3 packet. There are many ways to the router, LAN using router is commonly used to access wan access router type.
by for understanding, inside the cabinet is the cabinet has to know, not only for a new understanding of the whole cabinet, interior equipment and accessories is a new understanding.
