Analysis of router settings for integrated cabling of data centers

Good grounding of metal pipes can reduce interference and improve the line fire protection level of the equipment room. At the same time, the metal cable trough is used as the routing material to make full use of the cable slot's good scalability and easily add the characteristics of cables. Generally, the cable slots are arranged around the devices.

Currently, the parallel layout of cabinets and into racks is more and more common. Generally, a cable slot is arranged for each cabinet, or a cable slot is shared on the middle aisle of two adjacent cabinets. The former mode is more ideal.

For data centers with active floors, the usual practice is to install the cable trough under the active floor. However, with the widespread use of precision air conditioners for air supply under the floor in the high-end machine room, this mode exposes many problems.

Because the equipment is arranged in the data center, the cable slots are configured under the floor for each device. Generally, the height of the cable slots is between 50 and 50 ~ L 00mm, and the height of the active floor is only about 300mm, thus affecting the smooth air conditioning duct. The more the trough, the worse the air supply effect (there are usually strong electrical trough under the floor ).

In addition, the layout of lines, especially strong electrical lines, under the active floor also increases fire hazards. electrical faults may lead to fire sources, and human feelings under the floor are not easily discovered quickly, even if a conventional fire temperature and smoke detector is configured, the air supply under the floor does not reflect it quickly. There are already many fire accidents that occur under the active floor. Therefore, many data centers, especially in the telecom industry, generally adopt the online routing mode.

The layout of devices must be used for cabling. This layout is mainly applicable to standard Rack Layout, and the cabinet size, especially the height, must be basically the same to ensure beautiful appearance.

Use a cable trough for cabling. There are two installation modes for the cable trough: The bracket is hoisted on the top and the bracket is supported on the ground. Support on the ground is prone to fight between the bracket and the Cabinet. Pay attention to it during design.

There are two forms of on-line trough: Open Ladder Type Bridge Type and closed. The open ladder is the mainstream application. During the design, the layout of each cabinet is set one way according to the overall layout of the cabinets in the data center plane. The advantage of the open ladder is that it is easy to maintain.

Because no extra holes are required, it is very convenient to increase or decrease the line; no floor lift is required, and only a ladder is required for implementation, with a small workload. Easy to detect faults. Unlike the closed cable trough under the floor, it is easy to observe the fault point, especially the fire hazard. Its disadvantage is that it has higher requirements for anti-rat.

The open ladder frame is usually considered together with strong power. Generally, the upper, middle, and lower layers are used as channels for strong electrical lines, copper lines, and optical cable lines. Because a large number of optical jumper cables, especially in the data room, are relatively fragile, the Cable trays are often enclosed and such layout is easy to manage.

The distance between each layer is no less than 300mm. If the height of the data center is not high enough, you can also reduce the number of layers and use the left and right layout. Pay attention to the standard control of the distance between strong and weak current ladder frame. If the distance still cannot be reached, you can consider using a strong electrical screen or closed.
