Rittal cabinets – what are the common cabinet cable management processes?

First, the waterfall shape

This is one of the older wiring patterns that can sometimes be seen. It adopts the artistic image of "Huaguo Mountain Water Curtain Cave", and directly hangs the twisted pair from the module of the distribution frame, and there is a very beautiful sense of hierarchy when it is neatly distributed (24-48 twisted pairs per layer).

The advantage of this shape is to save the labor of cable management, but there are many disadvantages.

For example:

(1) When installing network equipment, it is easy to destroy the shape, and even it is not easy to install network equipment in place;

(2) The weight of each twisted pair becomes a tensile force, acting on the rear side of the module. If the twisted pair is not tied before the termination point, then this pull force may separate the module from the twisted pair after months or years, causing a wire disconnection fault;

(4) In case a module needs to be re-terminated in the distribution frame, the maintenance personnel can only probe into the "water curtain" for construction, sometimes wearing dozens of twisted pair wires, and because there is no light source in both directions, it is not clear when terminating.

2. Reverse line management

Reverse cable management is performed after the module of the patch panel is terminated and tested, and then the cabinet cable management is carried out. The method is to manage the cables from the module to the outside of the cabinet, and at the same time, the cable management is also carried out in the tray.

The advantage of this is that after the test, the cable management will not be re-managed due to the failure of a twisted pair cable test, and the disadvantage is that because the two ends (the inlet and the patch panel) have been fixed, there will inevitably be a large number of messy wires somewhere in the computer room (generally at the bottom of the cabinet).

Reverse cable management is generally manual cable management, which is completed with the naked eye and both hands.

The advantage of reverse cable management is that the test is already done and you don't have to worry about the cable length at the back of the cabinet. The disadvantage is that because the two ends of the cable have been fixed, there will be a lot of crossover between the cables, which is very laborious to tidy up, and there must be a twisted pair between the two fixed ends that is scattered, which is often under the floor (when the line is in) or on the ceiling (when the line is in.

3. Forward line management

Forward cable management is the process of managing the wires before the patch panel is terminated. It starts from the cable inlet in the machine room and sorts the cables section by section until it reaches the module of the patch panel. Terminate and test after cable management.

The objectives to be achieved by the forward management line are:

The horizontal twisted pair from the inlet of the computer room (or the network area of the computer room) to the wiring cabinet is based on each 16/24/32/48 port distribution frame, forming a bundle of horizontal twisted pair harnesses, and all the twisted pairs in each bundle are all parallel (the inter-wire crosstalk generated by the parallel twisted pair in a short distance will not affect the overall performance, because most of each twisted pair is laid in the bridge and the conduit, and this part is scattered and not parallel), and all the wiring harnesses are parallel to each other; After verification, it is fixed on the bracket behind the module or threaded into the module hole of the patch panel.

The advantage of forward cable management is that it can ensure that the cables in the equipment room are neat at every point, and there will be no cable crossing. The disadvantage is that if the cable itself has been damaged during threading, the test will not pass and the cable will be re-managed. Therefore, the premise of forward cable management is that the quality of the cable and threading is sufficiently certain.
