【 Cabinet Installation 】 Server Cabinet Installation Steps and Precautions Server Cabinet Installation Specification
Installation steps for server cabinet
List all equipment installed in the cabinet and their complete measurement data: height, length, width, and weight. The total height of these devices will ultimately determine how many devices can be installed in the cabinet. Obviously, a higher cabinet can accommodate more equipment and save space.
Of course, maximizing the height of the cabinet is not the only consideration, as there is also a large space at the back of the cabinet that can be utilized. This is the reason for measuring the depth of the cabinet. By choosing a deeper cabinet, two sets of equipment can be installed back-to-back, allowing for the installation of more devices. The above method can be used to install two rows of equipment in the cabinet, one row can be loaded and unloaded from the front door of the cabinet, and the other row can be loaded and unloaded from the back door. The cabinet should have adjustable positions.
After calculating the cabinet space (in units of "U" or 1.75 inches), the size of the room also needs to be considered. You wouldn’t want to find that you need to install more equipment soon after filling the cabinet. Once you buy and install the cabinet, these extra devices often appear. So, as a basic principle, the cabinet height should be increased by 20% to 30% for system expansion. These spaces also improve the ventilation conditions of the equipment.
Devices with brackets do not need to consider width, as they are designed according to the width of the cabinet. But for servers and other peripherals that cannot be mounted on brackets, the width cannot be ignored.
Due to the fact that the total weight of the equipment is often not light, it is necessary to choose a cabinet that can hold approximately 1500 pounds, which means selecting a cabinet with good load-bearing structure and sturdy structure. In the cabinet, the weight of the equipment determines whether the selected sliding frame is standard or weighted, and also determines the selection of other accessories. Choose a cabinet that is 100% compatible with all servers and meets or exceeds the third category bracket standards of all OEM manufacturers. If you wish to install tower or desktop devices, sliding frames and installation accessories are necessary.
Due to the installation of network cables, telecommunications cables, and power cables, it is necessary to purchase hook and loop or toothed straps to effectively secure the cables in an orderly manner inside the cabinet. If the cabinet is equipped with a cable management module that allows cables to be directly fixed in the vertical installation track, that would be great. In any case, there should be sufficient fixing rings on the upper and side walls inside the cabinet (to protect the cables), or the cabinet bottom plate can be lifted up for wiring underneath.
Key components for server cabinet installation
In addition to protecting servers, don’t forget that there are also some components that need to be installed in cabinets - network devices (hubs, routers, patch panels, keyboard/mouse/display sharers, tape drives, and storage) and peripherals (displays, keyboards, modems).
The most critical component is the power protector. In various installation rack configurations, all servers should have an uninterruptible power supply system as power protection. Even if the device only occupies 1U of space, it still needs protection. Even devices that do not require continuous operation should be protected with surge suppressors or linear regulators, which are included in the installation rack configuration.
Don’t forget about power components, such as power PDU sockets. If you don’t want more than ten power cords to extend out of the cabinet in a winding manner, you can use a power PDU socket. Although a 1U bracket model of PDU power socket can be used, it is best to install the 0U upright PDU power socket strip on the inner wall of the cabinet to make room for other devices. Remember, when purchasing a cabinet, the manufacturer must provide the PDU installation column on the side wall, which is a standard accessory. However, some defective cabinet vendors may secretly remove it to obtain better profit margins; Any components that cannot be installed with brackets require additional trays, bracket accessories, and other installation components.
Next, add up all the heat generated by the equipment to be installed. A 45U cabinet with good ventilation in all directions, allowing for an average total heat of 3000 to 5000 BTUs. If the total amount of heat exceeds the maximum heat value corresponding to the cabinet, it is necessary to purchase fans that can be installed on the upper or side walls of the cabinet. The upper wall fan is more expensive, but its effectiveness is twice that of installing it on the side wall. The side wall fan should be installed on the back wall of the cabinet, as most of the heat is generated at the rear of the equipment.
Attention to server cabinet installation
With the relevant dimensions of the cabinet, check the appearance of the equipment again to ensure that it matches the selected bracket. A sturdy cabinet can support up to 450 pounds, so check the tools used to remove the equipment, such as doors or handcarts. A good cabinet is equipped with wheels underneath, so you only need to install the necessary equipment and push the cabinet to the appropriate location.
Measure the size of the room and the height of the ceiling, doors, and elevator that the cabinet passes through. Furthermore, considering the various types of equipment inside the cabinet, ensure that the cabinet is placed close to the power supply, network cable sockets, and communication sockets.
Check the angle at which the cabinet door opens when opening and closing the cabinet. The standard cabinet door opens on the right and the door shaft is on the left, although the opposite cannot be ruled out. All doors and side panels should be easy to open for maintenance.
When you want to install equipment cabinets into an existing cabinet group, you can arrange the cabinets in a row next to each other for safety and neatness. However, some cabinet groups cannot be further added due to various reasons, or only a few accessories can be added. The best cabinet group model should have sufficient scalability and all necessary hardware. The cabinet side panels can be removed, and the cabinets can be connected to each other with screws and arranged in a row.
