Chapter 1. Safety inspection

A safety inspection is performed:

• When you inspect the system for an IBM maintenance agreement

• When there is reason to question the unit safety

• When IBM per call service is requested and no service has recently been performed by IBM

• When an alterations and attachments review is performed.

Attention:

IBM service personnel: The task of using a meter and probes to take voltage measurements

on receptacles/outlets must be performed by a Qualied Electrical Worker (QEW) or licensed

electrician. In countries where IBM service personnel are not qualied to perform this task,

the IBM service person must notify the customer that they must arrange for a QEW (a licensed

electrician may be considered a QEW) to perform the receptacle testing.

Refer to IBM's Global Electrical Safety Program for more information on QEW: https://

If the inspection indicates an unacceptable safety condition, the condition must be corrected before

IBM provides service to the machine.

Note: The correction of any unsafe condition is the responsibility of the owner of the hardware.

While performing this inspection, special attention must be given to these areas:

• Feature/model changes and Engineering Change (EC) upgrades

• Additions of non-IBM power supplies, logic cards, or attachments

• Missing safety covers

• Removed, faded, or painted-over safety labels

• Primary power parts replacement requirements

• Other product safety-related items.

Before you start, you must have completed the General Safety or equivalent course for this year.

Reviewed the Electrical Safety for IBM Service Representatives, S229-8124, or equivalent handbook.

Certain geographies might have different safety training requirements, see your safety training

requirements within your geography for more information.
