A data cabinet, also known as network cabinets or Server Cabinets, offers safe and secure storage for all your Networking Equipment such as Routers, DVRs, Networking Switches, Servers, and much more.
Network cabinets are often confused for server cabinets but there is a difference: that is, network cabinets are generally used for the storage of routers, patch panels, switches, and a wide variety of networking equipments and also networking accessories whereas server cabinets are mostly used to install servers, UPS ES, monitors or similar equipments.
A server rack cabinet is generally are generally 19 inches wide by industry standards but for the most part, are 24 inches wide and 36 inches deep. Server rack cabinets are usually perforated, front and rear to offer ventilation for the equipment being housed and also to provide safe environment for these equipments, which act as good heat emmitors.
Network cabinets on the other hand, are shallower than server cabinets, measuring in at less than 31 inches deep. Network cabinets will sometimes have glass or strong plastic front doors. Unlike server cabinets, network cabinets do not have perforated enclosures because the equipments housed do not emit a lot of heat.

DIFFERENT SIZES OF A CABINET
the height of the network cabinets is calculated in separate units, called U or ru (rack unit, rack unit). In particular, 1U = 1.75 inch (4.45cm), common sizes for you to choose include 42U, 36U, 27U, 20U, 15U, 10U . More specifically, a 9U network cabinet (standard size) will 19 inches (approximately 48cm) wide and 15.75 inches (approximately 40cm) high.The standard cabinets are at least 36 inches (900 mm) deep or even deeper. One particular server is 40 inches (1,000 mm) deep and requires a 48-inch- (1,200 mm) deep cabinet, Height, on the other hand, is often dependent on the room where the cabinets are located Therefore, it is important to have a variety of choices in heights and depths when evaluating the cabinet design. There are also significant design considerations inside the enclosure. to determining the height of the network cabinets is very important. You should not only consider the current use needs but also the future developments of.

small network cabinets is the most commonly used group of network cabinets for basic information technology needs (in offices, small businesses). They can vary depending on the particular situation. They are mostly used in imited spaces Small network cabinets (from 1U to 6U) are usually installed in height-restricted spaces, even wall mounted. Network cabinet also important to consider the weight of the network cabinet as in fact, some devices (such as UPS) may be bulky, heavy, and need a stronger network cabinet.
Medium size network cabinets: 18U, 22U and 32U
They are most commonly used network cabinets in small and medium sized companies and offices. Telecommunication devices, servers and network equipment can be installed in these cabinets, allowing for easier routing and cable routing, are often fitted with wheels to make them easy to move around the structure allows airflow from outside to inside and vice versa more effectively
Large network cabinets: 42U, 45U and 48U
cabinets models in this segment are sometimes called Higher-U. In particular, 42U network cabinets are the most commonly used type, sed for professional audio and video equipment, and of course, to accommodate both large-scale servers and network systems they are used in companies that provides networks large network cabinets are usually made up of sturdy metal frames, stand on the floor
DIFFERENT PARTS OF A CABINET
A server rack is made up of various parts, large and small. Although the names of its components are called different by each manufactures, they are similar in structure because of same use.
Main frame
There are a frame of “welding type” in which parts such as pillars and beams is welded together and “assembly type” which is assembled by connecting columns and beams with bolts or the like. It is greatly related to strength performance for shock resistance and earthquake resistance.
Mounting Rails
Mounting rails are for installing mount server. That is called mount rails, mounting rails and mount frame and so on.
Front Door
front door should be attached for security of the cabinets. We have both, closed door type and open door type.
Closed door type
Doors are attached to the entire surface of the door with acrylic windows, so you can check the contents from the outside plus the security performance is higher in this typ the heat is trapped in the server rack
Open door type
open door typehas A lot of holes on the surface so that heat does not stay inside of server rack. data center company really cares to manage airflow in data center. For that reason, many data center companies use open door type racks.
Rear door
rear door is basically the same as the front door. However, the front door and the rear door are not necessarily the same type of door., front door is a single door but rear door is a double doors. That can be changed for an usability
side panels
Side panels are attached right and left sides of a server rack. And are of different types one side panel covering with a server rack from bottom to top is fundamental version. Two side panels version is for ease of detaching. Used When cabling among server racks, because it has side panels which have cabling holes on side panels.
Top panel
Top panel is a part on top of a server rack. It is the same as side panels, there are many types such as cabling hole type, open type and so on. In Some cases you need to attach fans on top in order to dissipate heat in server rack, when you use closed door type rack because of a capability that warm air tends to flow from bottom to top.
Base
Base is a basement of server rack. Sometimes server rack is not needed to attach base .but . one of the reason why installing a base is for connection between a rack and ground.is because its used for earthquake resistance.
