6 Chassis Maintenance
Like all computer systems, you will need to perform some routine maintenance tasks. Some of these include making sure that the air vents in
the chassis are clear of obstructions and that the cooling air from the fans flows freely. You will also need to check the foam filter behind the
front panel to ensure it is clean, thus allowing for unrestricted air flow to the fans. You should always keep an eye on all cables to make sure
they are not damaged and are securely connected. Occasionally, you should remove the chassis cover and check for loose cards, and remove
any dust build-up.
Always remember to power down your computer and the expansion system BEFORE you attempt to perform any maintenance tasks.
6.1
General Chassis Cleaning
The environment where your OSS chassis is operating should be the determining factor as to how often you should perform a general cleanup
of the chassis. To perform a routine general cleaning of your chassis, you will need the following:
1. Can of compressed air (proper distance, 6 inches)
2. Cotton Swabs
3. Isopropyl (alcohol)
4. Anti static wipes.
Do not use a vacuum because vacuums create ESD.
First, remove the thumbscrews and the top chassis cover. Next, use a can of compressed air from your local computer store to blow out any
dust that may have accumulated in the chassis fans.
Be sure to keep the can of compressed air about six inches from the parts being sprayed with air. Pay particular attention to the fans in the
chassis and power supply because they are critical to air movement and to keeping your chassis cool. Also spray the PCIe slots on the
backplane.
Next, you can use anti static wipes to wipe down any open areas inside and outside of the chassis to remove any remaining dust or dirt. If you
have dust or dirt remaining in any “hard to reach area”, such as corners of a fan blade, you can use the cotton swabs, dipped in the isopropyl
(alcohol), to gently rub the area clean.
Lastly, if the chassis was extremely dirty, you can remove any installed 3rd Party cards and wipe the PCIe slots with a soft bristle brush (like a
toothbrush), dipped in the isopropyl (alcohol), to gently clean each slot. When finished, blow the slots with compressed air from about six
inches away until dry
.
Finally, clean the cooling fans following the instructions later in this chapter. When finished, replace the cover and turn on power to the
system.
