【 Weak current College 】 communications room design principles is important for fire warning

Sufficient spare space

With the rapid development of information technology, each desk at least need a PC and a telephone. In most cases, we are through star structured cabling system. Very simple, we need a place to put the star structure of core, around the creation of a runtime environment can be managed. However, this need to consume valuable housing area, at the same time, the loss of some effective work area, the owners always want more office space. If we ignore the problem, the network's performance can be greatly reduced, or even a business may be affected. This article is intended to describe communications room design process requires attention to key issues.

Room size and shape

Building area and effective area at the same time on the engine room space requirements are important, so we must proceed from the actual needs of users, such as Office desktop number and type of business, in fact, the requirements of the business number, the more you need more room to accommodate these devices. EN50174 on this gives a number of recommendations, requirements of reference of the cabinets around 1.2 m clearance. Communications room size can you have a number of rack, and then combined with the need to reserve the clearance, calculates the dimensions of the entire room. We may require the consent of the owners, the need to place the server communications room, computer room environment into account. In addition to the need for adequate housing space, you need the right lighting and temperature control. This in a later elaborated in more detail.

Other things to consider some factors such as the size of the door and the floor of the bearing. Door size involves the installation of some devices into issues such as 800mm cabinet cannot pass 2 ' 6 ". So at this point the use of double door may be easier and cheaper. We also must consider the load-bearing floor, whether these floors is structured floor or ordinary floor, server racks may not have any trouble, but for larger UPS uninterruptible power supply and storage area network equipment, we also need special consideration.

Suitable location

In the new building, we have the opportunity to choose the working area of the Centre to design the communications room, thereby reducing the length of the cable, this helps ensure that the cable length of the standard requirements, while reducing costs.

If possible, in multi-storey buildings can consider the vertical communications room, to simplify the design of the network backbone.

Electromagnetic interference sources need to be avoided, the workshop is a very easy to produce electromagnetic interference, there are some hidden sources of interference, such as copiers and laser printers, but also produce electromagnetic interference of killer.

Flooding is an important consideration, to avoid the communications room selection on the first floor, away from humid environment is very important.

To avoid overheating of the local setting communication rooms, not just from lowering air conditioners work to consider. In ordinary workshop, boiler and heat pipe is very easy to tell (the latter is also the danger of flooding), and some invisible heat source can be difficult to observe, if we could put the Cabinet is placed in the position of the window facing South, and there is the Sun easily radiation came in place.

Maintenance situation

Standardized communications room layout simplifies wiring system of management, however, when the change to be able to keep it clean clear server, cables, path, and space for labels is very important.

Appropriate lighting and air conditioning we have previously mentioned in the description, we can give wall paint color, a little note as appropriate lamp installation location, and other measures to make the room space suitable lighting easier to ensure that the Cabinet or head to have sufficient lighting to work. In the communications room, select heat and air conditioning (HVAC) is the control room temperature and the best way to ensure that any active device can work in the appropriate temperature, to function properly, rather than the temperature outside cooling Cabinet. Sealing the Cabinet to be able to prevent the cold air diffusion, and open rack on this great help, rack cooling channels equipped with a cooling fan to force air circulation guarantee equipment working temperature, not necessary to heat transfer through the floor. Ideal for HVAC should be able to form a positive pressure to reduce the dust from outside access and other pollutants.

AC power is required. From fuse structure leads to Cabinet wiring definitely than through a 13A socket out reliability. Of course we also don't exclude sometimes directly using some common outlet to provide power to the power tools or vacuum cleaner. Redundant power supply such as fast start-up of the generator or UPS is also very favourable configuration. Most UPS can deliver pure AC power, high-quality connections for communications equipment has always been very important.

Fire detection and early warning is one of the important considerations. Although the fire occurred rarely, but we also need to consider the corrosive gases for advanced communications room equipment. In the use of automatic sprinkler systems, dry pipe system is preferred. In those who use POC (flammable), in addition to the separate automatic nozzle, you want to place some detectors in the pipeline. This helps to prevent accidents, affecting the entire system. During the installation of water pipes, you must carefully consider the mains cable laying around.

Security and access

We have created a suitable space to serve as our communications room, we must also consider the room security can only be allowed some legitimate access into the system. Fortunately our intelligent cabling management system where you can swim a dew, a Cabinet has authorized patch changes can be detected automatically, and detailed logging, in addition, we also have a Web camera and e-mail to record illegal pictures alerts the network administratorOr security, at the time when these events occur in real time. Network management software in addition to the well-known security features, you can on a building multiple enterprise users to separate management.

Communications room should only meet the desired functionality of the device. Other devices placed easily lead to illegal access to, and sooner or later have accidents causing network problems.

The last word of advice

Highly reliable network is by no means verbal empty talk, create and maintain an appropriate communication in the engine room environment is the most basic principles, only on this principle, we can achieve our purpose.
