What are you going to put in your rack? If you are installing patch panels, a two-post rack with cable management may be the right choice. If you have a mix of networking equipment, servers and patch panels, a four-post rack provides a stable base and four-point mounting for deeper/ heavier equipment like servers and uninterruptible power supply (UPS) units. Four-post racks with front-to-back adjustable rails are suggested for flexible mounting of both standard and extra-deep equipment.
The main component of a rack is a set of vertical rails with mounting holes that you attach your equipment or shelves
The number of rack units is abbreviated as “U.” This is a measurement of the vertical space available on the rails. Cabinets, racks and rackmount equipment are all measured in rack units. One rack unit (1U) is equal to 1.75" of usable vertical space. For example, a device that’s 2U high takes up 3.5" of rack space. A rack that’s 20U high has 35" of usable vertical space.
Width is commonly given in inches, measured from one mounting hole to the corresponding hole on the opposing rail. The most common rail width is 19". To rackmount smaller equipment, add rackmount adapter brackets. Legacy equipment may require 23" rails and racks.
All critical equipment should be connected to a rack-mounted UPS. A UPS prevents your equipment from crashing during a brief blackout or brownout and allows enough time to shut everything down properly in the event of an extended power outage.
Rackmount power strips come in versions that mount either vertically or horizontally. Power strip options can include “metered” to show current draw or "outlet-managed" to monitor power and provide status updates and alarms.
Plotting your connections in advance will help you decide the most efficient way to organize your cables. Knowing where the connections are can help determine whether it’s better to run cables horizontally or vertically.
Many racks have built-in cable management troughs and cable rings for routing cable. If your rack doesn't have built-in cable managers, they can be added to accommodate your specific needs along with inexpensive hook-and-loop cable ties to hold and bundle cable securely.
For high-density cable management applications, there are specially designed systems with oversized channels and molded fingers. These molded fingers guide the wiring to mounted devices at precise increments while maintaining the proper bend radius for the cable. Completely removable covers allow for faster cable installation and protection.
A variety of solid, vented, stationary or pull-out shelves can make your rack configuration as efficient as possible: shelves built to hold specific pieces of equipment such as monitors and keyboards, cantilevered shelves for small items as well as center-weight shelves for larger, heavier items.
Rack-mounted panels designed to hold flat-screen monitors can be installed. Additional accessories include vented or non-vented fan trays and filler panels and grounding bars to ground the rack and the equipment in it.
