30 CABLE MANAGEMENT BEST PRACTICES When care is given to the management and maintenance of cable entering the rack or enclosure system, the goals of providing customers with a neat, organized and effective system are easily attained. Having a system that is simple and quick to service and upgrade will additionally benefit both the installer and the customer. When care is given to planning the management of cable entering the rack or enclosure system and maintaining it neatly throughout that system, the goal of providing the end-user with a neat, organized, effective and reliable system is easily attained. Methods of Bringing Cable Into Your Enclosure or Rack System Cable Entry: From Above Through Top of Rack Standard enclosure with wide-open top cable is dropped in from above. Middle Atlantic Products enclosures come standard with wide-open tops for large cable bundles to enter the enclosures. Standard enclosure with MW-10FT top option shown aluminum panel is removed to drop cable bundle into enclosure. Top can be replaced after cabinet has been cabled Cable Entry: From Below Through Bottom of Rack The bottoms of Middle Atlantic Products enclosures are designed just as the tops with a wide-open set-up to accept large cable bundles. There is 75 mm of space in the bottom of the enclosure before reaching the rackspace area to allow for cable entry up into the enclosure. Each enclosure s unique upformed base provides interior room for cable management and coiling unused wire. Dressing Your Cable Internally Vertical Lacer Strips When to Use Hook and Loop Style Ties Vertical lacer strips are designed to mount to the rail brackets in all Middle Atlantic Products enclosures. Add as many lacer strips as necessary in order to bring the maximum amount of cable into the enclosure, as well as keeping power & signal separate. The vertical strips allow the installer to lace cable from the top to the bottom of the rack or vice-versa. Hook and loop style cable fasteners like the TW12 should be used when installing cable that is sensitive to strain, when the wrap is so tight that it affects the performance,of the cable or when cable will be added to or removed from the bundle on a regular basis. These cable management straps can be opened and reused unlike wire ties. TW12 LACE-P LACE-44-1SP LACE-44-OWP LACE-44LP LACE-37LP Horizontal Lacer Bars Most of Middle Atlantic Products enclosures are furnished with a set of rear rackrail that can be used to mount the lacer bars at any height position. These lacer bars will address two common problems that occur: cable strain relief and running cables from one side of the rack to the other. Middle Atlantic Products offers different style lacer bars for different applications. Determine which lacer bar is appropriate for the application. Use lacer bars when running cables horizontally Use lacer bars as strain relief for connectors Use LBP-LTF Horizontal Lacer Panel When Running large cable bundles horizontally Rear support for equipment is required More surface to mount wires is desired Use Round Shape LBP-1R Lacer Bar When Running cable bundles vertically Running cable bundles horizontally that can be dressed then slid into position Using hook & loop fasteners Rear support for equipment is required Use L Shape LBP-1A Lacer Bar When Use L Shape Offset LBP-2A, LBP-4A, LBP-6A Lacer Bar When Positioning the lacer bar close to the rear of the unit for cable strain relief Managing multiple horizontal cable bundles at different depth positions Use Round Shape Offset LBP-1.5, LBP-1R4 Lacer Bar When Cable labels need to be seen (offset away from patch field or unit) Rear rail is set in one position and there are various equipment depths; allows placement of the lacer bar close to the rear of the unit for cable strain relief Managing multiple cable bundles horizontally at different depth positions Bend radius must be taken into consideration Running large cable bundles vertically Running fixed cables horizontally Using hook & loop fasteners Rear support for equipment is required 30 middleatlantic.com engineered mounting solutions since 1979

34 THERMAL MANAGEMENT BEST PRACTICES Maintaining the temperature inside racks and enclosures is critical to the proper functioning and survival of the circuits operating within. Most studies have shown that for every 5.5 o C rise over 29.5 o C, digital equipment life is reduced by approximately 40%. It is essential to ensure the heated air within the enclosure remains at a temperature of no more than 29.5 o C to help protect the sensitive equipment mounted within. There are two approaches to securing an adequate internal enclosure temperature for the successful operation of the components enclosed: passive and active thermal management. Passive makes use of the ability of a properly configured system to ventilate through natural convection. In certain cases, however, the use of fans to force air through an enclosure (active) is necessary to maintain the desired internal temperature. Please refer to the nomograph located on the following page to determine whether your system will require passive or active thermal management. In addition to the proper configuration of your rack system, room design is critically important to the success of rack and enclosure thermal management. It is essential that not only does the equipment room have the ability to remove the heat generated by the racks, but also that racks are placed strategically within the room to ensure no re-circulation of air occurs. Thermal Technique: Passive Thermal Management The passive approach to thermal management involves capitalizing on natural airflow. Adequate vent openings in the top and bottom portions of an enclosure, as well as an unimpeded airflow, and placing hotter equipment lower in the rack will enhance the natural flow of air, as heat naturally rises. There is a wrong and right way to approach passive thermal management: WRONG!

AMP AMP AMP AMP FULLY OR PARTIALLY VENTED REAR DOOR SIDE VIEW Thermal Technique: Active Thermal Management SIDE VIEW In many instances, equipment located within an enclosure will produce too much heat for passive thermal management (convection) to properly ventilate the enclosure. In this event, the use of forced air (fans) is instrumental to maintaining the optimal 29.5 o C temperature recommended. Keys to the successful implementation of active thermal design include the use of top-mount fan(s) and no venting in the upper 6 rackspaces, upper sides, upper front or upper rear door, to prevent short-circuiting of air at the top of the rack. There is a wrong and right way to approach active thermal management: WRONG!

AVOID VENTED RACK PANELS IN UPPER 6 SPACES OF RACK The key to successful active thermal management is ensuring there are no open vents at the top of the rack. The laws of static pressure dictate that fans will pull air from the easiest path (closest opening). This will create an undesirable recirculation of air, forming a stratification zone if upper vents are not blocked. 34 middleatlantic.com engineered mounting solutions since 1979

35 THERMAL MANAGEMENT BEST PRACTICES How to Calculate Ventilation Required to Provide an Interior Rack Temperature of 29.5 o C This nomograph will show the minimum ventilation (active or passive) required, to provide an interior rack temperature of 29.5 o C. To calculate total waste heat (column B): 1. Obtain total waste heat output by combining the published waste heat BTU/Hr. of all amplifiers in the rack. 2. Add up total measured amperage draw from all other equipment and multiply by 800 (total amperage x 800 = total 3. Combine BTU/Hr. totals from steps 1 and 2 to obtain total for all equipment. Mark total in column B. * When voltage doubles, amperage draw is cut in half. To obtain minimum ventilation requirements: 1. Mark ambient room temperature in column C and connect points in B and C with a straight edge. 2. The minimum cooling required providing an interior rack temperature of 29.5 o C will be shown on column A, where the straight edge intersects the minimum cooling requirements column.

It is essential that not only does the equipment room have the ability to remove the heat generated by the racks, but also that racks are placed strategically within the room to ensure no-recirculation of air occurs. The best start for thermal management is during the planning stages of new construction, by coordinating with architectural plans, building contractors HVAC plans and millwork specialists. However, regardless of whether planning is for a new or retrofit installation, there are several effective methods for thermal management that depend greatly on where the residential electronics system is being installed. A common residential installation features a visible rack face when it is mounted in millwork or a cabinet For a complete guide to thermal management and controlling the temperature inside equipment racks, visit middleatlantic.com to download the Thermal Management White Paper. Consideration to a rack s internal airflow is equally important to ensure effective thermal management. Simulations and real-world testing show that moving air through a cabinet from bottom to top results in the lowest internal cabinet temperatures for equipment with front intakes.

47 GLOSSARY TERM A & E Spec: Anodize: Definition An A & E Spec, or Architect s and Engineer s Specification Sheet, is a document that contains all of the information, including dimensions, materials, and weight capacities, in the format needed when specifying products. Our Architect s and Engineer s Specification Sheets are available on our website at middleatlantic.com, on our catalog CD, or in printed form upon request. A finishing process used on aluminum. This process, when used on our products, includes brushing to give an aesthetically-pleasing grained finish. GLOSSARY Bonding: E-coat: The permanent joining of metallic parts, likely to be energized, forming an electrically conductive path to a grounded conductor. An electroplating process that, when used on our rackrail, guarantees that the threads do not become clogged. EIA Compliant: EIA is the Electronic Industries Alliance. EIA compliant states that the rack and accessories conform to the 310-D standards regarding the rackrail, panel sizes, dimensions, etc. Ganging: Grounding: Isolated Ground: KD: KO: Powder Coat: Rackspace (Rack unit, RU, space): RackTools : When two or more racks are connected together, side-by-side. This is done in installations when multiple racks are permanently installed, facilitating cabling between racks. Also referred to as a multi-bay installation. The intentional connection of electrical equipment to a grounded conductor for safety. Type of ground that segregates the technical equipment ground from the local building safety ground, to reduce electrical noise from entering audio/video equipment. KD is short for knock-down, signifies a product ships flat-packed and unassembled. KO is short for Knockout, and applies to the knockouts that have been provided in most of our racks for electrical connections, and also for UHF/VHF antennas. One type of knockout consists of punched indentations in equipment cabinets, which can be easily knocked out using a screwdriver or other similar tool to create one of two different sized openings for running low-voltage cable, electrical conduit, connectors, etc. Another type of knockout is produced by a laser and produces smooth edges that are friendly to cables and contractors. Powder coat is an epoxy based finish that is applied electrostatically and then baked to cure the finish. Powder coating is an environmentally friendly process that does not release any harsh chemicals into the water or air. Powder coat is scratch-resistant and protects the materials from corrosion. A rackspace is a 44 mm vertical increment based on EIA/TIA standards and is how all 19" wide rackmount components are measured in terms of height. It is the only measure common to the metric and English systems. Applies also to 584 mm mounting widths. RackTools is a free layout and specification software package produced by Middle Atlantic Products. Containing our complete product line, RackTools is user-friendly and does not require any third party software to generate drawings, purchase orders and quotes quickly and easily. Please visit racktools.com for more information and to download your copy. Stand-Alone: TIA Compliant: Useable Depth: Racks modules that are used alone, i.e. ERK Series stand-alone enclosures. TIA is the Telecommunications Industry Association. TIA compliant states that the rack and accessories conform to standards regarding the rackrail, panel sizes, dimensions, etc. On racks the useable depth is based on the maximum front to rear rail depth, with the exception of wall racks, where the open space in the backpan is considered part of the useable depth. On a rackshelf, the useable depth is the maximum depth of the component that can fit on the shelf. engineered mounting solutions since
