Rack construction service
TPS are specialists in designing, building, testing, commissioning, and installing computer and telecommunications equipment racks for the data centre or telephone exchange environment. With thousands of completed builds, we have an extensive range of satisfied customers. We will work with you to develop equipment racks from concept to completion. Ask us how we can help you with your next project, TPS are the specialists in rack construction.
The first step is to meet with our engineering team and develop an elevation drawing. This will show how the equipment is located within the rack taking into consideration power consumption, heat displacement and connectivity issues. Once an elevation drawing has been developed, we will construct a prototype rack for you to investigate. After this prototype has been agreed upon, we will develop an electrical schematic which we will use to produce a ‘cable cut list’ and wiring schematic for tertiary power reticulation requirements.
At this stage, we will then work to develop a RF, Optical and or data cabling schematic. From the cable schematic, we can collaboratively produce a cable “cut-list”. We do this so that every equipment rack deployed is identical, cable reticulation is efficient & manageable, and every cable assembly gets installed in the same fashion and can be produced or as needed reproduced on an as-needed basis. Once cable flow is depicted and we have developed a cut-list, we then need to factor alarm and control circuitry into the design.
During the planning phase, we also prototype each of the developed items for the purpose of testing and visualisation. This process usually takes place with a vendors chosen active equipment, but if unavailable, then we will manufacture and utilise template equipment.
The planning phase can take quite some time, but when complete, we start the manufacturing process by receipting vendor supplied equipment (typically active equipment such as application modules, sub-racks, computer equipment, etc).
Each rack receives a placeholder label, typically this would be a deployment location, but if generic, then a tracking sequence number gets allocated so that we can track the rack from construction start to final commissioning.
After sub-racks and equipment is installed, the rack has been successfully elevated. At this time, we will manufacture and install the pre-cut and tested power cable looms allowing for tertiary power reticulation to the installed devices. Typically, in telecommunications racks, this tertiary cabling is more often DC, however in many situations we also install a invertor which will convert the DC to AC power to allow AC powered devices to also be installed (with necessary paint and rack-rack electrical protection)
Most of the telecommunications racks that TPS construct utilize large quantities of RF coaxial cabling. It is typically at this point that we manufacture install the RF cabling and data cabling. During the planning phase, we developed a cut-list, which gets loaded into our Schleuniger power strip cable manufacturing equipment. Once cut, the cable assemblies will get labelled with our Brady labelling equipment. We make a special point of using Brady cable labels and not laser printable sheet labels. Experience has shown that labels produced on a computer printer always fail and fall from the cables in a heated, production equipment environment.
Cable assemblies then have connectors fitted. For coaxial and electrical cables, we install with pressure regulated pneumatic crimpers. Use of this specialised equipment ensures uniform and reliable crimp and compression pressure, which is necessary to attain correct performance from RF cable assemblies. Once cable assemblies have had connectors fitted, they are individually tested for performance. After testing is complete, they can be gathered and grouped into “rack kits” ready for installation.
Rack installation of cable assemblies is performed according to a pre-determined installation and looking strategy, which differs for each rack. Specific cable are “tied” into looms, layered in a specific sequence. This “uniformity” ensures that all racks constructed are exactly the same. This is important for future operational and augmentation works that may occur in the racks future. If cables aren’t neatly tied back in a pre-determined fashion, any changes to an in-service equipment rack could result in unplanned service-interruptions.
