Chapter 5. Safety and Inspection
General instructions
Use this checklist to ensure that a machine not covered by an IBM Maintenance Agreement (that is, a
status 3 machine) has the necessary safety items that are installed and no other changes were made that
makes it unsafe or inoperable. Each machine, as it was designed and assembled, contains needed safety
items that are installed to protect the owners, operators, and service personnel from injury.
Note: This equipment is designed for connection to IT (impedance transformer) power subsystems.
Materials needed
The following items are needed or are useful during the inspection -
• Copies of safety service memorandums (SMs) and engineering change announcements (ECAs) for this
machine type
• Machine history
• Electrical Safety for IBM Customer Engineers, S229-8124
Education
Service personnel must be trained on the general maintenance agreement qualification (MAQ), tailored-
maintenance agreement qualification, and changed machine safety inspection procedures as part of the
electrical safety course.
Safety
The following notices are converted into selected languages, beginning on page “Sécurité” on page 166.
The general caution symbol
identifies conditions where caution must be used.
The electrical caution symbol
identifies electrical hazards where extreme caution must be used.
Complete this inspection before the normal inspection for a maintenance agreement. Suspect that the
3592 is unsafe until you verify that it is safe. If any unsafe conditions are present, decide how serious the
hazard is and whether you can continue without first correcting the problem. Possible safety hazards are -
Electrical
An electrically charged frame can cause serious or lethal electrical shock.
Mechanical
Hazards, such as a safety cover that is missing, are potentially harmful to people.
Chemical
Do not use solvents, cleaners, or other chemicals that are not approved for use on this product.
Any of the problems that are listed here must be repaired before you service or use the 3592.
DANGER:
When you are working on or around the system, observe the following precautions:
Electrical voltage and current from power, telephone, and communication cables are hazardous. To
avoid a shock hazard:
