The network cabinet has good technical performance, the structure of the cabinet should be based on mechanical properties and electrical use of the environment requirements, the chemical design and physical design, with good structure of the strength and stiffness and has a good electromagnetic isolation, noise, grounding and ventilation The Network /server Cabinets with anti-corrosion anti-corrosion impact, dust, water, radiation performance, to ensure stable and reliable safety of the cabinet work.
Network /server Cabinets with good practicality and safety protection, easy to operate, install, repair and to ensure the safety of operators. Network /server Cabinets In order to facilitate the production, assembly, commissioning and transportation, Network /server Cabinets must meet the standardization, standardization, serialization requirements, Network /server Cabinets out of the cabinet is more beautiful, more practical, more coordinated color.
Network /server Cabinets cabling in the wiring, tie is a skill, from the rear of the cabinet after the line. Order the line, do not twist. Line should be fixed and strong, do not sag, loose. The cable ties should be as symmetrical as possible on both sides. All kinds of wire joints should be left a certain margin, do not plug in the interface too tight. Do not block the outlet of the equipment as much as possible.
The PDU (power module) of the cabinet is installed as far as possible in the side panel of the network cabinet, and is neatly arranged as far as possible. Do not expose it to the rear side of the cabinet.
In order to insert the card (insert unit) into the chassis cabinet accurately, and to ensure that the plug seat is a good plug, there must be a guide device, this guide is called the guide rail. The guide rails play a leading role, but also reduce the plug and the plug of the plug and pull resistance, and to protect the chassis cabinet coating and metal surface is not due to plug and damage. In the design of rails, should meet the following requirements:
1, the guide rail must ensure that the plug-in box into the Network /server Cabinets when a better guide accuracy, and to ensure that the electrical contact device (plug socket) and fixed devices (connecting screws, etc.) connection.
2, the rail must ensure that the plug box inserted or pulled out when the minimum friction resistance.
3, the guide rail has sufficient strength and stiffness, can withstand the load imposed by the plug and the box, and the deformation is minimal.
4, the rail surface should have sufficient hardness, good wear resistance, strong coating, the use of reliable.
There are many forms of rails, according to their friction characteristics, the guide rail can be divided into sliding friction rail and rolling friction rail two categories. According to the characteristics of rail structure, rails can be divided into: self-styled rails and force-type rails. Self-sealing rails rely on the structure of the guide rail itself, allowing only a certain direction of the movement of the linear motion; force-type rails only in the external force (usually gravity) to help in the direction of movement of the movement in a given direction.
