Distribution Cabinets

According to the management line, the process can be found on the cabinet wiring system has special requirements. Production plants in the cabinet, often equipment cabinet (installation of public broadcasting, security, industrial control equipment), communications cabinets (installation of computer network equipment, optical terminal boxes and other equipment), server rack (installed on the server computer), and wiring cabinets (installation of an integrated wiring patch panel and computer network equipment) and other types of plants in the cabinet, most production equipment cabinets and server racks, dedicated to the cabinet wiring cabling systems are rarely produced. So many engineering companies in fact use the equipment cabinet or communications cabinet to replace the wiring cabinet.

Cabinet wiring cabling system is a special custom cabinets. The special point is to add some accessories unique wiring system, and the layout of the proposed special power requirements. For example:

In the cabinet's rear left side (looking forward from behind, between the rear panel and the column), all closed before installing a metal power groove, which extends from the bottom cabinet to the cabinet top, in which the top dedicated to the fan power socket. Vertical installation completely closed metal power groove to avoid disturbing the power generated on the level of twisted pair. In most of the cabinet, using a standard installation of the power delay line board, this structure makes it part of the power outlet and horizontal spacing between the twisted pair is less than 200mm, so it is not the ideal power distribution structure.

Bar-line panel: In the cabinet on the right rear (looking forward from behind, between the rear panel and the column), install two 100mm wide, iron, board, 10mm intervals along the vertical direction to open a 5 × 100mm waist hole, iron length of the base plate from the cabinet to the roof. Similarly, in the left rear (power supply between the tray and column) to install the same piece of iron. Alignment of the outer plate appearance requirement smooth, no burrs, so as not to damage cable, bar line piece of metal plate close to the ground power trunking, cable laying in the side and can only transmit voice-size on the number of cable;

Chassis: rear to open a 300 × 200mm square into a long line of holes, wrapped with a rubber edge, so as not to damage cable. 90mm above the hole, they may install a partition in order of appearance within the cabinet.

Before the column from the glass doors the vertical management trough between the two (with Cover, Gear-type structure, separated on both sides of the column outside).

Ground: from low up to the ceiling in the middle of the vertical rack installed a grounding strip, the copper strip on every 2U equidistant coarse teeth to open an M6 screw holes for the shield ground nearby patch panel, in which the bottom of the screw holes with lead to ground wire in the cabinet. Cabinet shall be grounded at all metal parts in order to achieve the overall ground cabinet and the cabinet on the ground should be grounded through the grounding copper Lead connected to the engine room of the ground copper rafts.

Both sides of the cabinet should have two sets and then the bolt holes and bolts with and then, when the number of secret levels the same wiring cabinet placed together side by side, it is best to use and then bolts to connect into a cabinet overall.

Patch panel mounting screws should be filled with (for 42U rack, the need to install the screws with 84 sets), to the objective of ensuring patch panels, network equipment and space.
