Chapter 2, Installing Your DigiSuite Hardware
Plan for adequate ventilation
Before using your DigiSuite-equipped system, you must ensure adequate
ventilation in your computer. Because some DigiSuite cards consist of two
printed circuit boards sandwiched closely together, the assembled units
produce a significant amount of heat. Forced air ventilation is therefore
extremely important, particularly if you plan to install DigiSuite LE with
its associated digital module or more than one DigiSuite card. Inadequate
ventilation may result in erratic operating behavior.
The best solution is to provide as much airflow as possible between the
cards; especially between the base and module boards of the card
sandwich. We recommend that you install a fan, as explained below:
q Position a fan directly facing the end of the DigiSuite cards with the
PCI retainer brackets. You should make sure the fan directs air
between the various circuit boards.
q The fan should have a minimum rating of 40 CFM (CFM stands for
cubic feet of air displaced per minute and is a measurement standard
for fans). An example of a fan that meets this requirement well is the
Sunon model KD1208PTB1, which is a 12 VDC fan with a rating of
42.5 CFM.
q Make sure to mount the fan as close to the cards as possible. In most
systems, you should be able to place the fan directly behind the card
guide slots, as shown in the above diagram.
q Make sure to close your computer’s cover once you’ve finished
installing your hardware. This ensures that the aiflow generated by the
fan is directed through the cards and does not escape through the top of
your system.
Important
Fan installation should be done by a qualified technician.
Improper installation procedures can result in damage to your DigiSuite
components and/or your computer system. Matrox Electronic Systems Ltd.
