In our last blog post we discussed the importance of cable management. This time we give you four expert tips that will help you keep your network cabinet tidy and will save you time and trouble.
Tip 1: Plan Ahead
Good planning is half the battle. Firstly, an operator should consider what requirements the network must meet. Is it a one-time setup that no longer needs to be touched, or is it a high-maintenance environment with critical downtime? The requirements of data centers also differ greatly from those of network cabinets. An operator should therefore plan his cable management appropriately and consider the arrangement of the components. This also includes providing space for cable ducts or rack units (RU) for cable management.
There are multiple possibilities ranging from classic 19" cable management panels to island solutions from cabinet manufacturers to complete solutions such as the PATCHBOX® Plus+ for cable management. However, the shortest or most direct route is not always the best. Cables should not run directly from one component to the next, as this would make access to servers and other hardware components much more difficult. It will cause dreaded chaos over time. It’s rather advisable to use horizontal cable management to guide the cables to the rail edge, where they are bundled at the side and directed to the target component.
Finally, planners should rely on electrical circuit diagrams. The cables should always run in straight horizontal and vertical lines and in the right angle.
Tip 2: Label Your Cable
Identifying and labelling cables is essential for simple and future-proof work on the network. It is always a good idea to attach a label at both ends. It is also worthwhile to be consistent and comprehensible in order to make it easier for colleagues to work on the cabinet. The choice of labels is also crucial. If an adhesive label is used that falls off at the first touch, the installer could have saved himself the trouble.
Clear assignment of cable colours to functions can make work much easier.
For example: blue = printer, white = telephone, red = critical.
Implementing colour coding also makes it easier for colleagues to find their way around the network.
TIp 3: Avoid excess cable lengths
Excess cable lengths are dangerous because they will lead to chaos. Luckily, there are several ways to solve this problem. On the one hand, an operator can measure the required lengths of patch cables beforehand and buy them as long as possible. This is of course not always feasible and costs a lot of time. On the other hand, cables can be assembled to the required length. In addition, an operator can fall back on helping systems, for which the PATCHBOX® Plus+ provides a product example. With its retractable cables, it always provides the appropriate length. A cable management system in which the cables are only out of sight, for example 1U brush panels, is best avoided completely by the operator. Although such systems provide a neat appearance at the front, knots, kinks and cable spaghetti occur on the back of the 19-inch unit.
SOLUTIONS SUCH AS THE PATCHBOX GREATLY SIMPLIFY CABLE MANAGEMENT BY ACCOMMODATING EXCESS LENGTHS.
After the assembly of patch cables, a measurement with a quality tester should be carried out in any case in order to ensure that a data transmission corresponding to the desired standard can take place. This step can ultimately prevent a lot of additional work.
Tip 4: Use High Quality Cables
Those who save on cables end up paying twice as much. Those who rely on cheap cables must expect poor shielding, small strand diameters and even copper-coated aluminium cores as conductors. These can break more easily and also have a worse electrical conductivity than copper. For non-specialists: The AWG number (American Wire Gauge) indicates the diameter of the conductor. The smaller this value is, the larger the conductor cross-section and thus also the electrical conductivity.
Data and power cables should always be routed separately, otherwise electromagnetic interference (EMI) can occur. With shielded cables, the risk of signal interference from EMI and radio interference (RFI) is lower. Nevertheless, it is important to ensure separate routing. This is known in theory, but not always implemented in practice.
