Frequently Asked Questions
Before You Buy
If a server rack accessory is listed on a server rack's product page under the Accessories tab, it will fit in the server rack.
Server racks offered by StarTech.com have an industry standard width of 19 inches, but can have varying height and depth. The mounting depth is important when you choose a shelf to be used as an accessory. Shelves that mount on all four corners of a server rack, such as 4-post server racks and cabinet server racks, will all have a maximum mounting depth. Many of these server racks and shelves are adjustable, which means that there will be a minimum and maximum mounting depth. This information can be found on individual product pages under the Technical Specifications tab. It is important that the depth of the shelf is compatible with the server rack's minimum and maximum mounting depths so that it can be mounted. If a shelf only mounts on the front on a server rack, the mounting depth is not relevant as long as there is enough clearance behind the mounting point to accommodate the full depth of the shelf.
Server racks are a great way to organize small spaces that require a lot of technology packed into them. However, there are a few important things you need to keep in mind before making a purchase. Today we will be explaining what a U is, and the differences between 2 and 4-post and open and closed server racks. We will also be covering what minimum and maximum mounting depth mean to you.
A server rack unit, or U, is a unit of measurement used to describe the amount of equipment space a server rack has. A U is 1.75 inches or 44.45mm high. An 8u rack has 8 units of vertical server rack space.
Note: Equipment can be more than 1U in size.
When you purchase server rack accessories they will list their size in U’s. Make sure the server rack has space to accommodate the accessory.
StarTech.com sells 2-post and 4-post server racks. 2-post racks take up less space but generally do not have as high of a weight capacity.
4-post server racks can be open or closed. Open racks are more accessible than closed racks, while closed racks can be locked for security purposes. Closed racks can include glass or mesh variations. closed server racks are generally better at reducing equipment noise and also limit external access. Mesh server racks provide better unmanaged airflow.
Adjustable 4-post server racks have a minimum and maximum mounting depth. The minimum mounting depth is the shallowest you can construct it. The maximum mounting depth is the longest measurement a product can be while still fitting in the server rack. If the server rack is adjustable, this measurement is also the deepest it can be constructed. Keep in mind that when you install equipment that is close to the maximum mounting depth, there will be little to no room for cable management at the back of the rack.
Server rack accessories my have their own minimum and maximum mounting depths listed on the product page under the technical specifications tab. It is recommended that you confirm these measurements will work with your server rack.
You should consider the following things when shopping for server racks:
- You can mount equipment on both sides of a 4-post rack, provided the combined measurements of both items are under the server rack's maximum mounting depth.
- Decide if you want casters on your server rack, want your rack bolted to the floor, or if you want to leave it free standing. StarTech.com offers racks that come with casters and racks that you can bolt to the floor. StarTech.com also sells casters separately. Casters that fit on your server rack will appear on the StarTech.com product page under accessories.
In this video, guidelines and best practices will be discussed for constructing server racks. Constructing a new server rack can be a bit daunting, but there are some general guidelines that you can use when you assemble most of the server racks StarTech.com sells. Let’s have a look at the guidelines.
Before You Begin
- Make sure there’s enough room where you will be building.
- If you intend to move the rack, make sure it will fit through any doors or hallways.
- Make sure that you have all of the parts listed in the manual.
- Make sure that you have all of the tools that you will need.
- Assemble the rack in the correct order, according to your manual.
- Double-check that everything is where it should be and then tighten everything down.
- Be careful not to strip screws.
- Install casters and any server rack accessories.
Now that you have reviewed the guidelines, you can begin assembling the server rack.
It is advised to take all of the parts out of the box and ensure they match up with the parts outlined in the manual.
You should also make sure that you have all of the tools that you need.
First, the adjustable beams should be assembled.
On this server rack, these adjustable beams control the depth of our rack and are marked with Index numbers. The Index numbers allows you to set the depth of your rack, based on your equipment. Make sure that you choose the same Index numbers for all of the adjustable beams. You can use the measurement chart in the manual for reference.
As you screw in your first screws, it is a good idea to only tighten them finger tight. That way, if you need to unscrew anything, you can do so easily.
You should now have your adjustable beams together.
You will now use the beams to line up one set of left and right vertical rails and the top and base brackets. It is often easiest to build the rack on its side.
There are a few important things that you should check for at this point in the assembly:
- Make sure that the numbers on the adjustable beams and vertical rails are facing the right way
- Make sure that you refer to the manual for the fastening pattern as this is crucial to the rack’s stability once it is assembled. The same fastening pattern will be used for the other corners of the server rack. For this rack, you can see that the screw is going through the top or base bracket, then the vertical rail, and then into the adjustable beam, in that order. This is essential and will be the same for all of your corners.
The two adjustable beams, two of the vertical rails, and the top and base brackets should all be in place now. You can now attach the other two vertical rails and our final two adjustable beams.
It’s time to double check that everything is in the right place before you tighten all of the screws. Make sure that the numbers on your beams are all facing in the correct direction, the fastening pattern for each corner is correct, and that all of the cable guides are facing in the same direction.
Once you are sure that everything is correct, you can go ahead and tighten your screws, remember to be careful not to strip them.
Now that your rack is fully assembled, you can attach the casters and server rack accessories. Note that all of your casters and server rack accessories should be installed facing in the same direction. You may find it easier to invert the server rack to install the casters.
As you can see, rack builds are fairly straightforward as long as you take your time. If you experience issues in setting up your StarTech.com server rack, contact the technical support team for further assistance.
This video is about cage nuts and describes how to install and remove them, and how to identify if your product includes cage nuts.
You may have heard of cage nuts and wondered what they are and how they are used. Today we are going to discuss cage nuts and show you some of their advantages and uses.
Cage nuts are used to mount IT equipment in server racks, such as the StarTech.com 4POSTRACK25U. Server racks compatible with cage nuts can be easily identified by the square holes the cage nuts use. Cage nuts are great for protecting your equipment from stripped threads and allow for convenient mounting of your server rack equipment.
A cage nut houses a standard nut in a cage with a spring. The cage has two wings that can be pinched together to allow the cage nut to be inserted into a square hole. The wings are then released to hold the cage nut in place. Cage nuts come in many sizes but M5 and M6 cage nuts are mainly used in IT environments. M6 is a heavier, more robust cage nut that M5.
Let’s take a look at mounting a Cage Nut on a rail in the StarTech.com 4POSTRACK25U.
In some situations, you may be advised to use a slot screwdriver to help install cage nuts. However, you will find it much easier to use a cage nut mounting tool.
To install a cage nut, use your tool to attach one of the wings from the cage nut. Keep the pressure on the cage nut with your finger and then attach the other wing. The cage nut is now ready for the mounting screw.
To uninstall a cage nut, use your tool to release the cage nut wing on one side and then the other side.
You can check to see if your StarTech.com product includes cage nuts by navigating to the StarTech.com website, searching for the product, and checking the Technical Specifications tab under the heading What’s in the Box.
StarTech.com also sells cage nuts and screws in both M5 and M6 sizes which can be seen by navigating to Server Rack Accessories and the section Mounting Screws and Cage Nuts.
When you install your rack equipment, it’s important to put the heaviest equipment on the bottom of the rack, first. This provides a strong base and is especially important if you are installing a lot of equipment on a tall rack. This also prevents the server rack from becoming top heavy and falling over.
If your equipment is long, heavy, unbalanced or otherwise difficult to handle, ask someone to help you install the equipment so you don’t injure yourself or damage the equipment.
Finally, when you tighten down your screws make sure you don’t strip or damage the screws. This is especially important to be aware of when using electric tools which can generate more torque.
The patch panel will be mounted using cage nuts, so the first step is to install them.
Once installed, the cage nuts can be used to mount our patch panel.
To install your server rack equipment, fasten the mounting screws into the cage nuts. After you tighten your screws, check to make sure your rack equipment is securely installed.
If you have questions about installing equipment into a server rack, contact our technical support team for further assistance.
