Network Rack: Five Tips For Choosing Cabinet Racks

When choosing a Network Rack, size matters

When specifying a network rack, there are a few key dimensions to keep in mind.

The first is the panel height. This is different from the overall height because it is the empty space where components can be installed. It's basically the height of the rack opening. It is important to add up the heights of the items to be installed to ensure they all fit easily. Don't forget to include any ventilation space you may need between components. That doesn't mean the overall height isn't important. We have clients who ordered a large rack only to find that the ceilings in the rooms they use are not high enough. Finally, make sure the deepest components have enough depth space.

What is your approach to installing components in a network cabinet?

All network cabinet racks are equipped with panel mounting rails. These are long, relatively thin, profiled metal pieces that are used in pairs to mount the assembly's mounting ears into the rack. They are usually pre-drilled on the EIA spacing. EIA spacing is an industry-standard that dates back more than 100 years to the early days of telephony. The holes on your device and panel mounting rails will be set according to this standard, which is based on the space between 5/8", 5/8", ½", 1-3/4" total holes This dimension is called a unit The "u" of the rack is usually specified as a multiple of "u" or 1-3/4". Typical dimensions for a network cabinet rack are 45u (77") or 46u (78.75").

Where do you plan to place your network closet?

The location of the rack is an important determinant of choosing the right rack. If it's in a closet, as often happens, your concerns are far more important than in an open space. If it's a closet, a simple cabinet shelf will do, since you're already protected by the closet itself. You might even decide to use the smaller wall mounts that are very popular in these applications, especially if the components are very light. If it's going to be in the middle of an office, you need to focus on making sure it looks professional and protecting the components from the curious.

Do you need ventilation or other features?

There are many ways to ensure the components you install have the proper level of cooling so they don't overheat. It can be as simple as not requiring a front or rear door on the cabinet or making sure the sides or top of a door or all of the above contain vents or slots. Other issues that may need to be considered include whether unique cable access is required to include the correct access point. Also, what are the access issues for maintenance? Often, the ability to easily remove sides or doors allows for quick repairs or adjustments without uninstalling components.

Need accessories for your rack?

Does the manufacturer include popular accessories such as shelves, power strips, fans or blowers, or cable management hardware? Sometimes these items don't fit easily on cabinet shelves if they come from different manufacturers. Are you moving your device to another location? Then you want to make sure you can add casters.
