Seven hard conditions that must be considered when purchasing outdoor communication cabinets

Outdoor cabinets are often much stricter than indoor cabinets because they have to withstand the harsh weather outside, including sun and rain. Therefore, the quality, material, thickness, and processing technology will be different, and the design hole positions will also be different to avoid exposure to aging.

Let me introduce to you the seven major factors that we need to evaluate when purchasing outdoor cabinets:

1. Reliable quality assurance

It is very important to choose a suitable outdoor communication cabinet and wiring cabinet. A little negligence may lead to huge losses. No matter which brand of product it is, quality is the first thing that users must consider.

2.Load-bearing guarantee

As the density of products placed in outdoor communication cabinets increases, good load-bearing capacity is the basic requirement for a qualified cabinet product. Cabinets that do not meet specifications may be of poor quality and cannot effectively and properly maintain the equipment in the cabinet, which may affect the entire system.

3. Temperature control system

There is a good temperature control system inside the outdoor communication cabinet to avoid overheating or overcooling of the products in the cabinet to ensure efficient operation of the equipment. The outdoor communication cabinet can be selected from the fully ventilated series and can be equipped with a fan (the fan has a life guarantee). An independent air-conditioning system can be installed in a hot environment, and an independent heating and insulation system can be installed in a cold environment.

4. Anti-interference and others

A fully functional outdoor communication cabinet should provide various door locks and other functions, such as dustproof, waterproof or electronic shielding and other high anti-interference performance; it should also provide suitable accessories and installation accessories to make wiring more convenient. Easy to manage, saving time and effort.

5. After-sales service

The effective services provided by the company, as well as the comprehensive equipment maintenance solutions provided, can bring great convenience to users' installation and maintenance. In addition to taking into account the above points, the outdoor communication cabinet solution in the data center should also consider the design of cable planning, power distribution and other aspects to ensure the good operation of the system and the convenience of upgrades.

6. Power distribution system

How do outdoor communication cabinets cope with the increase in power density? As the trend of high-density IT installation in cabinets becomes increasingly apparent, the power distribution system becomes a key link as to whether the cabinets can perform as effectively as they should. Reasonable power distribution is directly related to the availability of the entire IT system, and is an important basic link in whether the entire system can perform its intended performance. This is also an issue that has been ignored by many computer room managers in the past. As IT equipment becomes increasingly miniaturized, the density of equipment installation in cabinets continues to increase, which poses severe challenges to the power distribution system in outdoor communication cabinets. At the same time, the increase in input and output ports also places high demands on the reliability of the power distribution system installation. Taking into account the current dual power supply requirements for most servers, power distribution in outdoor communication cabinets becomes more and more complicated.

The design of a reasonable cabinet power distribution system should follow the principle of reliability design as the center, specifically designed for the cabinet system, and fully coordinated and seamlessly coordinated with the power distribution system. At the same time, the convenience of installation and intelligent management should be taken into consideration. , strong adaptability, easy operation and maintenance and other characteristics. The power distribution system of the cabinet should bring the power supply closer to the load to reduce shortcomings in the power path. At the same time, local and remote monitoring of load current and remote control of power distribution should be gradually completed, so that power distribution management can be integrated into the overall intelligent management system of the computer room.

7. Cable planning

What should I do if there is a cable problem? In a large computer room, it is difficult to walk through the numerous outdoor communication cabinets, let alone quickly find and repair faulty lines. Whether the overall disposal plan for the cabinet is in place and the management of cables in the cabinet will become one of the key aspects of the investigation. From the perspective of cable attachment inside outdoor communication cabinets, today's data centers have higher cabinet configuration density, accommodate more IT equipment, use a large number of redundant accessories (such as Foshan electrical appliances, storage arrays, etc.), and frequently configure equipment in the cabinets. Changes, data lines and cables are added or removed at any time. Therefore, the outdoor communication cabinet must provide sufficient cable channels to allow cables to be entered and exited from the top and bottom of the cabinet. Inside the cabinet, the laying of cables must be convenient and orderly, close to the cable interface of the equipment to shorten the wiring distance; reduce the space occupied by the cables, and ensure that there is no interference from wiring during the installation, adjustment, and maintenance of the equipment. , and ensure that the cooling airflow will not be obstructed by cables; at the same time, in the event of a fault, the equipment wiring can be quickly located.

When we plan a data center including servers and storage products, we often don't care about the "minutiae" of outdoor communication cabinets and power supplies. However, in the theoretical installation and use of the system, these supporting equipment also play an important role in the reliability of the system. Impact. From the price point of view, outdoor communication cabinets and racks range from a few thousand yuan to tens of thousands of yuan, which cannot be compared with the value of the internal equipment in good condition. Due to the concentration of equipment inside the cabinet, some particularly "harsh" index requirements for outdoor communication cabinets and racks are determined. If no attention is paid to the selection, the trouble caused during use may be huge.
