How to choose the right cabinet

Is a important part of the cabinet finishing cabinets line, there are three kinds of common reason line process:
the waterfall model
this is a relatively old wiring modelling, sometimes also can see the sight. It adopted 'huaguo mountain waterfall cave art image, from the distribution frame module twisted-pair cable directly to heaving, has a very beautiful administrative levels (distribution and tidy 24 - on each floor 48 twisted pair) 。
this is the advantage of saving the line of artificial management, faults are more, such as: when installing network equipment is easy to damage modelling, appear even is not easy to install in place of the network equipment; All become tension, the weight of each twisted-pair function in the module of the back. If before the end contact not to tie of twisted pair, this tension is likely to be in a few months and years separated from twisted pair, the module cause disconnection fault; One thousand one module in the distribution frame needs to be termination, the maintenance personnel can only into construction within the 'water' sometimes with dozens of twisted pair, and because there is no light source, two-way cause termination can't see.

reverse bedding line reverse principle line is in distribution frame module after the termination, and through the test, and then to wire racks. Its method from outside the module to the cabinet line management, line at the same time also undertaken within the bridge. Do this has the advantage of the principle line after the test, not caused by a twisted-pair cable test pass it on to line management, and the defect is due to both ends ( Service entrance and distribution frame) Has been fixed, somewhere in the room will appear a lot of disorderly line ( Usually at the bottom of the cabinet) 。
lines to reverse the principle for artificial reason commonly, with the naked eye and hand finish line.
reverse line has the advantage of test has been completed, do not worry about cabinet back cable length. And shortcomings because has fixed on both ends of the cable, cable between will produce a lot of cross, to tidy is laborious, and between the two fixed end there must be a twisted pair is messy, this place is often under the floor, Next in line) Or smallpox ( Aspirant line) 。
forward Richard line
are in line is distribution frame line before termination. It from room service entrance, cable segment, until the module of distribution frame. After the right line termination and test again.
forward Richard line to achieve the goal: the room ( Or computer network area) A level of service entrance to wiring rack mouth twisted pair to each 16/24/32/48 distribution frame, forming bundles of horizontal twisted pair wiring harness, each line within all the twisted pair of parallel ( Within short distance between parallel the twisted-pair cable crosstalk will not affect the overall performance, because the bridge and the cable pipe laying, with each for most of the twisted pair, this part is the scatter, is unparallel) , all parallel between the wiring harness; After each conveniently bending beam of twisted-pair cable inside the cabinet laid to the back of each distribution frame, the process still maintain twisted-pair fully parallel in the wiring harness. Back at the end of each module from the bottom of the wiring harness, extract the module of the twisted pair, after verification fixed in line after the module rack or wear into the module of distribution frame hole.
forward Richard line has the advantage that can ensure the cables in every point in the room tidy, and there will be no cable cross. And at the time of the threading the disadvantage is that if the wire itself has been damaged, the test pass it will cause the line again. Therefore, forward line is the premise of enough grasp about the quality of the cable and the threading.
are in line has the advantage of computer room, Computer room area or weak current) Since the service entrance to distribution frame between all tidy, parallel, very beautiful. The disadvantage is that the construction personnel to the quality of their construction has fully grasp, only on the basis of basically not to termination to forward line construction.
