A PDU, known in full as a Power Distribution Unit, is a device used to manage and supply electric power in data centers. The market features various types of PDUs and PDU manufacturers. For instance, rack PDU manufacturers develop unique types of PDUs, known as rack PDUs. A rack PDU is a particular link in the power chain in data centers. This helps ensure the delivery of critical power to specific network loads. Rack PDU manufacturers often use network racks in their facilities.

What are network racks?

Network racks, sometimes known as network cabinets, are structures used to store networking equipment. This equipment includes network switches, routers, cables, patch panels, UTM appliances, modems, and servers, to name a few. Network racks are usually closed to ensure the safety of the equipment stored.

How large are network racks?

Network racks may feature varying sizes. However, the size depends on the size of the equipment stored in them. Note that there are industry standards or networking hardware equipment. Therefore, network rack manufacturers also follow these standards for the hardware to fit in them.

Thus, the standard width of a network rack is about nineteen inches. This size allows for any networking equipment to fit without any hassles. It is also worth mentioning that network racks have fixed heights. A network rack or cabinet may contain several rack units.

A single rack unit usually measures 1.7 inches. Therefore, the height of the network rack depends on the number of rack units it houses. Hence, if a network rack has three units, it will feature a height of 5.1 inches. A few inches may be added to accommodate the devices freely.

Why are network racks necessary?

Below are reasons why institutions purchase network racks:

1. Storage

One of the vital roles of a network rack is to store networking equipment safely. They work like storage units for various types of equipment in data or IT centers. Note that network racks can hold several components in a small space. This means that using network racks will help save you a lot of floor space. It also allows you to utilize your storage space more efficiently.

2. Equipment performance

These racks can also be used to enhance the performance of networking equipment. They do this by ensuring that cables are neatly and carefully taken through the cable managers within the racks. Doing so ensures that there are little to no chances of data loss due to excessive bends on the cables. Some network racks also come with cooling fans. These elements help prevent damage to the networking equipment because of overheating.

3. Security

In addition to storing the equipment, network racks are also used to enhance the physical safety of networking equipment. They work by denying access to unauthorized personnel. This prevents theft and physical damage.


Network racks are essential elements in a data center. They help by providing the benefits listed above and more. They also help enhance productivity and promote the organization in the data center. Network racks are often confused with server racks. However, server racks are specifically designed for storing servers.
