IBM I 1700 manual Handling Electrostatic Discharge-Sensitive Devices

ŸExplosive hazards, such as a damaged CRT fa bulging capacitor.

ŸMechanical hazards, such as loose or missing ware.

The guide consists of a series of steps prese checklist. Begin the checks with the power off, power cord disconnected.

Checklist:

1.Check exterior covers for damage (loose, b sharp edges).

2.Power-off the computer. Disconnect the power

3.Check the power cord for:

a. A third-wire ground connector in good con Use a meter to measure third-wire groun nuity for 0.1 ohm or less between the ground pin and frame ground.

b. The	power cord	should be	the appropria
as	specified in	the parts	listings.

c. Insulation must not be frayed or worn.

4.Remove the cover.

5.Check for any obvious non-IBM alterations. Use

judgment as to the safety of any non-IBM al

6. Check inside the unit for any obvious unsafe tions, such as metal filings, contamination, wat other liquids, or signs of fire or smoke da

7.	Check	for	worn,	frayed,	or pinched	cables.
8.	Check	that	the power-supply cover fasteners
	or rivets)		have	not been	removed or	tampered

Handling Electrostatic

Discharge-Sensitive Devices

Any computer part containing transistors or integra cuits ( ICs) should be considered sensitive to discharge (ESD). ESD damage can occur when there difference in charge between objects. Protect damage by equalizing the charge so that the m part, the work mat, and the person handling the at the same charge.

Notes:

1.Use product-specific ESD procedures when th exceed the requirements noted here.

2.Make sure that the ESD protective devices have been certified (ISO 9000) as fully eff

When handling ESD-sensitive parts:

ŸKeep the parts in protective packages until

inserted into the product.

ŸAvoid contact with other people.
