If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
vElectrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock).
vExplosive hazards, such as a damaged CRT face or bulging capacitor
vMechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.
Checklist:
1.Check exterior covers for damage (loose, broken, or sharp edges).
2.
3.Check the power cord for:
a.A
b.The power cord should be the appropriate type as specified in the parts listings.
c.Insulation must not be frayed or worn.
4.Remove the cover.
5.Check for any obvious alterations. Use good judgment as to the safety of any alterations.
6.Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.
7.Check for worn, frayed, or pinched cables.
8.Check that the
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.
Notes:
1.Use
2.Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling
vKeep the parts in protective packages until they are inserted into the product.
vAvoid contact with other people while handling the part.
vWear a grounded wrist strap against your skin to eliminate static on your body.
