What is open rack?

Open Racks

An open rack is a type of framework used in data centers, server rooms, and IT environments for mounting and organizing various electronic
equipment, typically networking and server equipment. Unlike enclosed cabinets, open racks do not have sides or doors. Here are some key characteristics and uses of open racks:

Structure and Design:

  • Standardized Sizing: Open racks are usually built to standard dimensions, with the most common width being 19 inches. The height is measured in rack units (‘U’), where 1U equals 1.75 inches.
  • Frame Style: Consists of just the frame, often with two or four posts, providing mounting points for equipment.


  • Easy Access: The lack of sides and doors allows for quick and easy access to the equipment for installation, maintenance, and troubleshooting.


  • Airflow: Open design facilitates better airflow around the equipment. This is particularly beneficial for equipment that generates a lot of heat, as it helps in keeping the temperatures down.

Cable Management:

  • Ease of Wiring: The open structure makes it easier to route, organize, and manage cables. This is advantageous during setup changes or when adding new equipment.

Cost and Space Efficiency:

  • Cost-Effective: Generally less expensive than enclosed cabinets due to their simpler design.
  • Space-Saving: Can be more space-efficient in certain layouts, especially in areas with good environmental control.


  • Security and Protection: Offers less security and protection from physical or environmental factors compared to enclosed cabinets. It’s not ideal for areas with dust, moisture, or where unauthorized access is a concern.

What is open rack?

Ideal Environments: Best suited for controlled environments like data centers or server rooms where additional security and environmental protection are not as critical.

Open racks are a practical solution for environments where frequent access to equipment is necessary, and there’s less concern about exposure to environmental hazards or security issues. They are commonly used in IT, telecommunications, and network setups for theirsimplicity, cost-effectiveness, and ease of use.

How to select/chose the right open/frame rack?

Organizing a computer room or data center, especially when dealing with limited space and expensive equipment, requires making the most of the available area. This is where solutions like open frame server racks come into play, offering benefits that are particularly valuable for network facilities.

Benefits of Open Frame Server Racks:

Cost-Effectiveness and Accessibility: These racks are affordable and provide easy access to equipment and cabling, making maintenance simpler and less expensive.

Airflow: With no walls or side panels, open frame racks allow unrestricted airflow, helping to keep equipment cool.

Load Capacity: Two-post racks can support up to 1500 lb (680.4 kg), while four-post racks can hold up to 2200 lb (1000 kg), making them suitable for a range of equipment.

Choosing Between Two-Post and Four-Post Racks:

Two-Post Racks: Ideal for lighter equipment such as patch panels and fiber enclosures, especially when the equipment depth is less than 20 inches (510 mm).

Four-Post Racks: Better for larger, heavier equipment like network switches, as they offer more support with front and rear mounting options. When selecting a rack system, it’s important to consider factors like durability, safety, security, stability, and strength. Additionally, planning for rack mount dimensions is crucial:

  • Width: Ensure the rack width matches the width of your equipment.
  • Depth: Particularly for four-post racks, the depth must be carefully chosen to fit your equipment.
  • Height: The rack height determines the number of available rack-mount unit (U) spaces.
  • Space Planning: Leave adequate aisle space in front and rear of the rack (at least 3 feet) and sufficient clearance above and around cable runways.
