Standard Server Rack

Which shelf would work best in my server cabinet? The general rule of thumb is to measure 6” shorter than depth of cabinet for all 4-post cabinets. This measurement will compute the optimal shelf depth for your particular cabinet enclosure. Also, please take into consideration that rails are often set at a distance less then the actual depth of the internal dimension.

	Solid Flat Shelf - Sometimes called a stationary or fixed rack shelf, a flat shelf mounts to all 4 mounting rails of a 4-Post Server Rack / Electronic Enclosure. Due to its simplicity, Flat Shelves will often occupy less than 1U of rack space. Weight Limit: 150 lbs.
	Adjustable Shelf - Similar looking to a flat shelf, Adjustable Shelves attach to all 4 mounting rails of a 4-Post Server Rack / LAN Enclosure. The main difference between the two is the rear mounting ears for the Adjustable Shelf are adjustable by 4" less than the shelf depth and 4" more than the shelf depth. For example, an 18" Adjustable Shelf can mount on posts ranging from 14"-22" deep. Weight Limit: 150 lb s..
	Heavy Duty Vented Shelf - Heavy Duty shelves are constructed in a special manner in order to accommodate particular mounting needs. Heavy Duty shelves occupy a full 1U (1.75”) of rack space and will support a weight up to 300 lbs. Heavy Duty shelves attach to all 4 mounting rails of a 4-post server rack. Weight Limit: 300 lbs.
	Sliding Keyboard Shelf - This specialty shelf is designed to accommodate rack optimized keyboards. The Sliding Keyboard shelf attaches to all 4 mounting rails of a 4-post server rack enclosure. Weight Limit: 75 lbs.
	Vented Flat Shelf - Ventilated Shelves are equal to standard shelves, though, ventilation slots provide additional air circulation between rack units. Ventilation Shelves mount to all 4 rails of a 4-post server cabinet. Weight Limit: 150 lbs.
	Sliding Pullout Shelf - Pullout shelves are useful for positioning non-rack mountable equipment in a server rack which needs frequent access. Sliding Pullout Shelves mount to all 4 mounting rails of a 4-post server rack. Weight Limit: 150 lbs.
	Sliding Rotating Keyboard Shelf - Designed to accommodate standard sized keyboards, these shelves rotate as unit extends beyond the cabinet to make it easy to type on a standard keyboard. These shelves mount to all 4 mounting rails of a 4-post server rack enclosure. Weight Limit: 50 lbs.

Side Panels

Side Panels

Side panels offer security and Side panels are available in 3 options: solid fixed, solid removable, and louvered.

Server Rack Cabinet Removable Side Panel

Removable Solid Side Panels: These are recommended should you need occasional side access to your equipment, or if you intend to gang rack enclosures together. If you order 2 or more racks, you will only need one set of Left and Right Side Panels for the rack enclosures on the ends of your row of enclosures - racks in the middle would not require them as they will be ganged together. These allow you to have access to the side of the cabinet. The doors have latches on the front side and can be released. When released, the panels open like doors. Each removable side panel adds .75 inches to the width of the cabinet. Keep this in mind when figuring out if you have room for the cabinet. Fixed Solid Side Panels: These are an economical option for those who do not need side access to their equipment, or are buying a single rack and not planning to expand or gang rack enclosures together in the future. These panels are permanently attached to the Server Rack and maintain the original dimensions.

Anti Tip Feet

For mid to top heavy loaded racks, retractable Anti Tip Feet stabilize cabinets ensure your Server Rack will not fall over.

Casters

Casters attach to the bottom of server cabinets to help maneuver racks around the data center. Two of the four wheels lock to assist with keeping the Server Rack from rolling.

Levelers

Levelers should be used if Casters are implemented to ensure that the rack remains level once it’s moved from one place to another. Both Casters and Levelers will install together on your server rack to provide maximum stability.

Air Circulation

A fan is the best way to maintaining a safe operating temperature for valuable rack equipment. Fans attach to the top panel and assists with removing hot air from the server cabinet. A fan mounted on the top of your Server Rack will help to keep your servers at a cooler temperature. A fan is an exhaust fan so it is pulling the hot air out of your server rack bringing in the cooler air from the bottom of the server rack. A single top mounted fan that we offer is rated at 550 CFM single phase 50/60 Hz.

Servers Door

Front Doors

Front doors are available in many different sizes and ventilation options. Locking mechanisms are available on most doors; however, please check with our engineers before designing and ordering.

Perforated Steel w/ Plexiglas Window - Perforated steel door installed with a Plexiglas window.	Plexiglas Door - An Aluminum frame surrounds a full-length Plexiglas window.	Steel - The solid steel door ships with no holes or windows.	Perforated Steel - Perforated steel door creates additional ventilation.	Louvered - A solid steel door with ventilation slots

Rear Doors

Rear doors are also available in many different sizes and ventilation options. Locking mechanisms are available on most doors; however, please check with our engineers before designing and ordering.

Cooling tip: adding a ventilated front and rear door will assist with air circulation by creating a front to back flow pattern.

Mesh - Perforated steel door adds ventilation to any size rack enclosure.	Louvered - A solid steel door with ventilation slots to help assist with rack ventilation.	Solid - A steel rear door

Top Panels

Vented Top Panel

Vented Top Panel with 4" Hole for Cabling

A top panel will help secure servers and valuable rack equipment from foreign objects that could enter into the Server Rack from above. Top panels can be ordered with perforated slots for added ventilation along with grommet holes for supplementary cable management pathways. Top panels are also designed to accept exhaust fans to help pull hot air out of the rack enclosure.
Please note that specialty cabinets such as Dust and Water Resistant Server Racks will not support ventilated or fan.

Server Rack

Universal Mounting Rails EIA Standard 10/32 Tapped  Mounting Rails

Rack Mount Rails: We can manufacture server rack enclosures with either Universal Mounting Rails (square holes fitted with cage nuts) or with EIA Standard rails (10/32 tapped holes). All our cabinet rails are high quality gauge steel (1/8" thick or more) and have an electroplate finish to maximize protection. Universal Mounting Rails: Universal rails will support 19" EIA width rack mount and networking equipment and almost all sever equipment. Cage nuts and screws will be needed in order to mount equipment to universal mounting rails. EIA Standard Mounting Rails: Standard Mounting Rails support 19" EIA width rack mount and networking equipment and some sever manufacturer's rack mounting equipment. Please be aware that not all rack mountable equipment will match up against the EIA 1032 hole pattern on Standard Rails. Standard mounting rails will not allow the use of Cage Nuts. Which Mounting Rails do I need? It depends on the equipment you will be mounting in the rack enclosure. Most rack mount and networking equipment such as hubs, routers, patch panels, etc. will conform to EIA Standard hole spacing. However, some sever and rack accessory manufacturers will implement rack mounting kits to assist with attaching equipment to Universal Rails. With this example, proper cage nuts and screws will most likely be needed in order to mount this type of rack mount equipment in one of our server cabinets.

Mounting Hardware
There are currently 3 types of Mounting Hardware used with our server cabinet rails:
10-32 Tapped Cage Nuts and Screws - American Version - Commonly used in all rack mount applications including music, video, broadcast, data and more.  The "10" refers to the drill size for a tapped (threaded) hole. The outside diameter of a 10-32 screw is 0.19", it is smaller than a 12-24 screw. This screw type has 32 threads per inch.
12-24 Tapped Screws - American Version - The "12" refers to the drill size required for a tapped (threaded) hole (a #12 drill is 0.189"). The outside diameter of a 12-24 screw is 0.2160". It is larger than a 10-32 screw.  This screw type has 24 threads per inch

M6 Tapped Cage Nuts and Screws - Metric Version - Metric thread size of 6 millimeters. Typical thread size for European rack applications. Also used in Compaq racks and Euro racks sold here in the US. Larger than both 10-32 and 12-24.
What mounting hardware do I need?
It depends on the mounting rails of the rack enclosure or relay rack you will be ordering. Most 4-Post server racks, cabinets, LAN enclosures either use Cage Nuts and Screws for square hole type Universal Mounting Rails or 1032 tapped screws for round hole style EIA Standard Mounting Rails. Please be aware that almost all 2-post open relay racks use 1032 Tapped Screws (round hole mounting rails).
