The Difference Between Various Types Of Network Racks

A cabinet PDU, also known as a free-standing PDU, is a large, ordinarily three-phased power distribution unit that comes in a cabinet. A power distribution unit is a device used to manage and supply electric power to data and IT centers. Cabinet PDUs are used in large data centers that require raised and non-raised floor applications. The PDUs take incoming power and distribute them into an individual or group of racks. Cabinet PDU manufacturers use network racks in their facilities. This excerpt looks into various network rack types.

Types of network racks

The most popular types of network racks are:

1. Wall-mounted network racks

As the name suggests, these network racks are typically installed on the wall. They come in varying sizes ranging from 6-15 units. Note that a unit is 1.7 inches. Therefore, a 6 unit network rack is usually 10.2 inches long. Wall-mounted network racks are commonly used for housing edge devices in independent departments.

They are also popularly used in areas where less networking equipment is needed. Most wall-mounted network racks have a single glass door in the front to allow access to the cables. They are also commonly made with steel frames made with aluminum enclosures. The materials are strong enough to handle the weight of the networking equipment stored inside. Note that these types of network racks can not be used to store servers.

2. Floor-standing network racks

Floor-standing network racks are used for storing both network and server equipment. Note that they are primarily applied in data centers and places with large quantities of equipment. This is because they are typically larger and kept on the floor. A typically free-standing rack features between 24 to 45 units (one unit is 1.7 inches).

Some free-standing network racks are usually designed with wheels attached to them which helps promote movement. These racks offer specialized channels for electrical and network cabling. This element ensures the neatness of the cables. In addition to holding large equipment, they can also accommodate heavier equipment. A standard free-standing network rack can hold between 450 to 500 kgs worth of equipment.

For this reason, they are made from the best metal on the market. Aluminum is the most popular type of metal used to make these network racks. This material can accommodate the weight and size of the equipment.

Which one is the best?

Each of the network rack types listed above has its benefits and disadvantages. Additionally, they are both designed for specific applications. For instance, if you are looking for a large rack that can handle large and heavy equipment, then a free-standing network rack is the ideal choice. On the contrary, if you want a smaller one, a wall-mounted rack is the best option. In simpler terms, the application and type of equipment you wish to store in the rack will help you pick the best option.
