If you follow the following check order, you can choose not only conforms to the installation of your priorities, including safety, durability, compatibility and easy to loading and unloading) , cabinets and not beyond your budget. . .

To telecom data center rental cabinets or just rent space cabinet intermediate 1 u, 2 u, believe everyone understand better how one thing, however, some of the telecom room not only provide cabinets leasing service, even can also provide room rent, is part of the user to sign the room space, rooms ISP to provide users with access lines and power supply, refrigeration facilities condition, this kind of business is generally to large users, customers only need to tell room operators, the specific requirements for operator, tailored, can be flexible wiring, and network configuration for the client, good nature is charging flexible, let customers don't need to spend big self-built room can enjoy top equipment room is comfortable and smooth, the placement of the most important still is the customer free cabinets and equipment needed for yourself!However, if your choice of network cabinet is not appropriate,install the most valuable part of the installation--the server will be installed in the cabinet, and you will find that there is little room left for the cabinet. On the contrary, if you follow the following check order, you can choose not only conforms to the installation of your priorities, including safety, durability, compatibility and easy to loading and unloading) , cabinets and not beyond your budget. The first

consideration should be security. Putting IT equipment into a locked cabinet will make IT easier for network administrators to limit the number of people who can open the cabinet.Physical requirement

List all the equipment installed in the cabinet and their complete measurements: high, long, wide and heavy. The total height of these devices will ultimately determine how much equipment can be loaded into the cabinet. Obviously, high cabinets can fit into more equipment and are more efficient.Of course, use the height of the cabinet is not the only consideration, the rear of the cabinet also has a lot of place to use. That' s why you're measuring the depth of the machine.Choose a deep cabinet, can install two sets of equipment back to back, install more equipment thereby. In this way, two rows of equipment can be loaded in the cabinet, one row from the front door of the cabinet and the other from the back door. The cabinet should be adjustable.

After calculating the cabinet space (in "U" or 1.75 inches) ,consider the size of the room. You don' t want to see the cabinets stuffed up and soon find that you have to put in some more equipment. Once you buy and install the cabinets, these extra devices tend to come up. Therefore, as a basic principle, the cabinet height should be 20% to 30%more for system expansion.These Spaces also improve the ventilation conditions of the equi pment.

The device with a bracket does not need to consider the width

because it is designed according to the width of the cabinet.But for the server and other peripherals that cannot be installed, the width cannot be ignored.

Since the total weight of the equipment is often not light, you should choose a cabinet that can hold about 1500 pounds. That is to say, you should select a strong and strong cabinet. In the cabinet,

The weight of the device determines whether the selection of the sliding frame is standard or heavier, and the selection of other accessories is also determined. Select the cabinet that is 100% compatible with all servers, and it should meet or exceed the third bracket standard of all OEM manufacturers. If youwant to install tower or desktop devices, sliding racks and installing attachments are required.

Due to the installation of network cables, telecommunication cables and power cables, you need to purchase the belt or belt of the belt to effectively keep the cable in the cabinet. If the cabinet is equipped with a cable management module, the cable can be fixed directly in the vertical mounting rail. In either case, the upper wall and the side wall of the cabinet should have enough fixed rings (to protect the cables) , or they canbe carried on the bottom of the cabinet so that the following line can be taken.

Cabinet type and class

Although cabinet looks almost the same, but different segmentationup according to its use and there are several types

of common is used for wiring rack and is used to put the racks of servers, used for wiring rack is usually used to place more than one terminal switches, so there will be a lot of cable need to pick up, cabinet is not convenient to get a door, so that the rack looks more like rack, also had a cabinet manufacturer called this product wiring; In addition to the server racks are certainly a door have a lock, because to protect valuable equipment inside, so the more expensive the routers, firewalls,general is on the rack.

For server cabinets, there are also grades:

Common server cabinet

This is a normal server rack, glass door, the server rack cooling fan has four, installed at the top of the rack, mainly used for ventilation cooling purposes, provide a good constant temperature environment for the inside of a cabinet, cabinet is at the bottom of the hollow out, used for ventilation and heat dissipation. The server at the top of the cabinet has very good heat dissipation, but the lower part of the server is not very good at heat dissipation.

Advanced server cabinet

Above this kind of rack is relatively high-end server rack,thickly dotted on the QianHouMen wind hole for ventilation and heat dissipation, so the roomair conditioningair conditioning can be a very good distribution within each server around to the cabinet, the cabinet of the cooling effect is good, and this kind of rack materials standards, anticorrosion, bearing

capacity is strong.

Key component

In addition to the server need to be protected, don't forget to still have some parts need to load the cabinets - network equipment (hubs, routers, distribution frame, the keyboard/mouse/display sharing, tape drives, and storage) and peripherals (monitor, keyboard, modem) .

The most critical component is the power protector. In various installations, all servers should be protected by a continuous power supply system. Even if the device takes up the space of 1U, it needs to be protected. Even devices that do not require continuous operation should be protected by an electric surge suppressor or linear regulator, which is available in the installation configuration.

Don' t forget the power parts, such as a power socket. If you don' t want a dozen power lines to reach out of the rack,You can use apower socket. Although you can use the power socket of the 1U support model, the power socket bar can be installed in any corner of the inner wall of the cabinet to make room for other devices. Remember, any component that cannot mount a bracket requires additional pallets, support accessories, and other installers.

Next, addupall theheat generated by the device to be installed.A 45U cabinet, which is well ventilated at the top and bottom,allows for an average of 3,000 to 5000BTUs total calories. If

the total number of calories exceeds the maximum number of calories in the cabinet, you will need to purchase a fan that can be installed on the wall or side wall of the cabinet. The upper wall fan is more expensive, but the effect is installed on the side wall twice. The side wall fan should be installed in the back wall of the cabinet, since the rear of the device generates most of the heat.

Installation attention

With the relevant dimensions of the cabinet, check the shape of the equipment to ensure the matching of the bracket. A sturdy cabinet can carry up to 450 pounds, so check out the tools used to take out the equipment, such as a lift door or a trolley.A good cabinet is equipped with wheels, so you can simply pack the equipment and push it to the right place.

Measure the size of the room and the height of the ceiling, door and elevator. In addition, considering the multi-class equipment in the cabinet, make sure to place the cabinet in a place close to the power supply, cable socket and communication socket.

Check the Angle of the cabinet door when opening and closing the cabinet. The standard cabinet door opens on the right, the door axis on the left, and of course not the other way around.All doors and side panels should be easily opened for maintenance.

When you want to install the device cabinet in an existing cabinet unit, you can place the cabinets in arow, safe and tidy.

However, some cabinets cannot be added for a variety of reasons,or can only add several attachments. The best cabinet group model should be fully expandable and with all the necessary hardware, remove the side panels of the cabinet, connect the cabinet with screws, and arrange them in a row.

Price factor

Prices always have to be considered, but they can't be sacrificed for important features. Need to choose the most cost-effective cabinet. Servers and peripherals change quickly,but good cabinets take a long time. Comparing the advantages and disadvantages of the cabinet, the key is to compare several recognized performance indicators. In performance metrics, pay attention to the word "attach", which indicates that it is allowed to be extended at any time. Many vendors give you only see cabinet unit price, not including cabinets shall be installed in the equipment price, and the equipment can make your spending quickly become bigger, so you have to consider cabinets plus a full set of equipment price, don't at the meeting by the manufacturer.

Finally, select the manufacturer of the production cabinet. The service life is recognized as a performance standard, and the manufacturer should have a department to help you install the cabinet, install the equipment properly, and provide you with the accessories within a few years after the sale. Also, make sure the manufacturer offers a lifetime maintenance of the cabinet.
