2-Post Computer Server Racks “101”

One size does not fit all when it comes to server racks. The classic 2-Post Rack (also known as a “telco rack” or “relay rack”) is the most economical way to store 19-inch rack mount equipment, such as computer hubs, power backups, and rack mounted servers. In our two-part series, we will discuss characteristics of a 2-post relay rack (versus a 4-post rack), available configurations, and customization options (something TechRack uniquely offers).

2 Post Racks are often used instead of the conventional Server Racks, Computer Cabinets or Wire shelving Units, but they do have a few limitations.

Security and Temperature
Because 2-Post units are generally set up to be open, one must consider both security and air flow requirements in determining where they are to be situated. In terms of security, consider whether the equipment requires security, if the rack location will be in a small office so that only one person or a few people have access to it or if the racks are housed in a secure room or a “fenced in” area which provides the most security. For equipment that needs constant air flow due to high temperatures, open racks are best suited to meet this requirement, especially if they are installed in non-congested spaces.

Strength. No Matter How Light.
Any two-post rack you purchase should be sturdy and strong, whether it is used for storing light or heavy equipment (note: standard weight capacity is typically 750 pounds, evenly distributed). Techrack, as an example, only sells heavy-duty steel racks with upright channels, outfitted with heavy-duty and top-and-bottom aluminum angles. These are of knocked-down (KD) construction. For storage of even greater loads, consider the use of fully welded 4-Post open frames.

Know Your Equipment Layout
When configuring your relay rack requirements, there are a variety of heights available to accommodate office or data center equipment needs, such as 48″, 68″ or 84″. When it comes to rack spaces (“U”s), these range from 24U, to 45U. Note: 1U = 1.75 inches.

Don’t Forget Add-ons
There are some state and city ordinances that require bracing for earthquake-prone areas. Techrack offers universal earthquake bracing kits so that a rack can be secured to the ceiling or wall. Another method for securing a rack is a floor bracing kit (with seismic tie-down openings). An additional potential server rack requirement to consider is whether mobility around the office or data center is required. Techrack offers specially made relay rack rollers for this option (note: weight capacity is 300 pounds). It is unsafe to attach wheels or casters directly to the base of a relay rack.

Expand Your Space
If you want to have more room for equipment space altogether, you can also create a double telco rack by connecting two 2-post racks together to create a 4-post open rack. This method uses adjustable horizontal braces to connect the two relay racks together (more on this in our next blog post on 4-post racks).

Tailor to Your Exact Needs
One of the unique offerings Techrack provides in the industry is the ability to customize relay racks to meet specific needs that are not “standard equipment needs,” for instance, a rack with computer shelves, blank panels and power strips. In other words, you can take a modular approach to building your rack to create exactly what suits your needs. Customization can be wanted for a variety of reasons: an unusual configuration or shape of equipment, a working environment that may expand in the future, or having an odd office or data center footprint.

TechRack makes it easy to order customized 2-post racks; just select the frame you want and then add on the components you desire.
