1 Introduction

1.1 Overview

The procedures in this document ensure that a 3494 not under a TRT maintenance agreement has

the necessary prerequisites installed and available to ensure a transparent transition and an

uninterrupted maintenance service during the period of the TRT maintenance agreement.

1.2 Education

All service personnel must be trained on the general maintenance agreement qualification, tailored

maintenance agreement qualification, and changed machine safety inspection procedures as part of

becoming a TRT Technical Service Representative (TSR). In addition, service personnel must also

be trained on the 3494 prior to servicing the equipment.

2 Safety and Inspection

2.1 General Information

The safety checklist procedures in this topic ensure that a 3494 not under a TRT maintenance

agreement has the necessary safety items installed and that no changes made it unsafe. Each 3494,

as designed and assembled, has safety items installed to protect operators and service personnel

from injury. These checklist procedures verify only these items.

The safety checklist procedures must be performed before the normal inspection for a maintenance

agreement. The 3494 must be considered unsafe until the presence and condition of all checklist

items are verified. If any unsafe conditions are present, you must decide how serious the hazard is

and whether you can continue without first correcting the problem.

When performing the safety checklist procedures, consider the following conditions and the potential

safety hazards they present:

• Electrical, especially primary power. For example, an electrically charged frame can cause

serious or lethal electrical shock.

• Explosive. For example, damaged or expanding capacitors can cause serious injury.

• Mechanical hazards, such as missing safety covers, can cause injury to service personnel.

2.2 Preparation

The following reference items are useful during the inspection:

• The LOC section of the 3494 Maintenance Information manual

• Copies of safety service memorandums (SMs) (see Appendix B) and engineering change

announcements (ECAs) (see Appendix A) for this machine type

• Parts catalog

• 3494 history

• Electrical Safety for TRT Technical Service Representatives

2.3 Branch Circuit CB Switched Off Check

Task Date Owner ü / û

1. Locate and switch off the circuit breaker (CB) for the 3494

branch circuit that supplies voltage to each receptacle TRT /

Customer

2. Perform one of the following for each receptacle:

Note: There is a line cord for each control unit frame and drive

unit frame in the library.

• If this is a metal clad connector, perform the

“Safe-to-Handle Check” and the Disconnect

Precautions” procedures in Electrical Safety for

TRT Technical Service Representatives. (These

procedures are described under “Miscellaneous

Safety Tips.”)

• If the power cord has an insulated plug, grip the

plug without touching any metal parts, and

remove the plug from the customer power

receptacle

TRT /

Customer

3. Perform the “Power Receptacle Safety Check” in Electrical

Safety for TRT Technical Service Representatives TRT

4. DANGER Hazardous voltages are present. Do not touch

the internal parts (pins and sockets) of the outlet.

• Measure the phase-to-ground voltage at each

receptacle

• If a neutral is present, measure the phase-to-

neutral voltage, phase-to-ground voltage, and the

neutral-to-ground voltage

• If all voltage values are not less than 1.0 V ac,

have an electrician check the circuit

neutral voltage, phase-to-ground voltage, and the

neutral-to-ground voltage

• Record the voltages for future reference in the

checklist shown in the following table

2.5 Safety Labels and AC Grounds

Understand the meaning of the safety labels before beginning any repair of a component with a

label.

Check that the labels are located where shown in following figures. Make any necessary corrections.

See IBM 3494 Tape Library Dataserver Parts Catalog for part numbers of labels in the various

languages.

2.7 Safety Labels and Grounds for the Model D1x

Use the previous figure keys 6 through 8 and 10 through 12 for the locations of the safety labels and

grounds in the drive unit frame.

2.8 Safety Labels and Grounds for the Model S10

The storage unit frame does not contain any safety labels or grounds.
