There are countless approaches which that is one of our goals, provide packages that are universal and can be effectively used in various configurations. The following are simply suggestions and intended to provide an example of how to use the products. A big consideration is also the type and size of rack, the configuration, of course the equipment installed in the rack... The best approach is to always stay focused on the basics which is to simply get air moving within the rack and when enclosing a rack or system in general, it has to also be vented.
We should also note that while we are happy to help all of our customers, if you are a DIY customer and this appears overly challenging, you may want to seek a local professional to assist you.
The general idea of this package is to use a Universal Cooler in the top of the rack if the front of the rack is open but sides, top, and/or back enclosed. The second Universal Cooler can be used above another heat producing component or even in the bottom of the rack to blow cooler air into the rack. Note that the UCs can also be mounted in the back of the rack if there are rear rails. The Component Unit should be used above one of the hottest components and the DUO units are then intended to be set on components as a spot cooler.
Universal Coolers. First consider the location and orientation of the unit as the unit can be mounted and configured to pull air in or exhaust air and also blow upward or downward as well. Do note that you do not want to blow air directly into a component so that is a consideration. Once decided, simply mount the UC to the rack using the provided screws.
Component Unit 4- Fan w/Cover. This unit is intended to take air from within the rack and above a component and directly vent it out of the rack. This unit is installed by first attaching the rack 'ears' to the sides of the unit and then installing the unit into the rack. It is recommended to control this unit with the ASC controller.
DUO Unit. This is intended to simply sit on top of a heat producing component so attach the provided rubber feet and select a position on the desired component. Also consider how it can best be used to mix the air in a rack, if there is a central spot where simply moving the air will disturb and displace air.
Temperature Controller. The Advanced System Controller is intended to control two banks of fans and with this package I would recommend controlling the Component Unit with one bank and then the exhaust fans as the second bank of fans. The 3-Fan Advanced LT controller will control 3 sets of fans independently and most likely will run DUO units on one bank of fans. Do not place the sensors directly on components as they should not be touching metal surfaces. For the ALT it is easiest to decide on the program prior to installing the controller into the cabinet and it is common to simply run the controller with all 3 banks of fans set to 90F. Do not set to lower temperatures as the fans may never turn off. The higher alarm settings (125F) may be desired for rack applications as well because even with proper venting temperatures can still reach 115F and above.
Power Supply. The ASC will have it's own fixed voltage power supply while the other power supply is simply connected to the controller and if it is a variable voltage unit, it should be ALWAYS be set to 12V.
Wiring. Most wiring uses the 2-pin connector while some components use a 2.1 coax connector which should be provided and needs to be connected to the 2-pin connector end. When plugging wires together, always ensure to align Tip to + or + to +. See the diagram in the pics for different configurations as generally the temperature controller plugs inline between the power supply and fan units.
Optional Fan Kit
Use this kit if your rack has openings for 120mm (4.75") fans. This is an easy and affordable way to add valuable cooling but we do caution to keep the effectiveness in perspective. For example, if have an open rack and the opening in the top, this will primarily just provide cooling for the very top of the rack. Now in contrast, if it is an enclosed rack it can provide ventilation throughout the rack. For our suggestion on how to wire and use the fans with the controller, reference the wiring image.
