Service Inspection Safety Procedures for the 3745, 3746-900, and Controller Expansion

Important

This procedure addresses the 3745, 3746-900, and the controller expansion. If one of these machines is not present, ignore the statement concerning this machine in the following procedure.

Introduction

A safety inspection procedure for the 3745, 3746-900, and controller expansion should be performed:

 When it is inspected for an IBM agreement  When IBM service is requested and no service has recently been performed by IBM  When an alterations and attachments review is performed  When changes have been made to the equipment that might affect its safety.

If the inspection indicates unacceptable safety conditions, the conditions must be corrected before IBM services the machine.

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

Safety

The 3745, 3746-900, and controller expansion areas and functions checked through these procedures are:

1. External covers

2. Safety labels

3. Safety covers and shields

4. Grounding (earthing)

5. Circuit breaker and protector rating

6. Input power voltage

7. Power control switch

8. Power ON indicator.

4Grounding (Earthing)

Note

In this book, "ground" means that the equipment must be connected to the earth.

a Grounding on the 3745

Refer to YZ110 for grounding jumper/contact locations. . Check that:

 Electrical continuity is assured between the frame ground and the terminals indi-

cated on the ground distribution diagrams.

 Electrical continuity is assured between the 3745, frame grounds, and to the premises

grounding system, through the 3745 power cord.

b Grounding on the 3746-900 and Controller Expansion to the Premises Grounding

System

 Electrical continuity is assured between their frame ground and premises grounding

system through their power cords.

 The 3746-900 is grounded to the 3745 via the power control cable (see Figure 0-1 on

page xx).

 For the controller expansion, an additional ground wire .A/ is also used (see Figure 0-2 on

page xxi, Figure 0-3 on page xxii, Figure 0-4 on page xxiii, or Figure 0-5 on page xxiv).

START

Chapter 1. START: How to Begin Troubleshooting

Important

 Your personal safety can never be over-emphasized.  You have been taught safety procedures since the earliest phase of your IBM training.  Your safety is part of every maintenance call.  You are the only one who can make a maintenance call safe.  Specific information can be found in “Product Safety Information” on page xvii and “Safety Label

Locations” on page lvii.

Start here when you use this manual to repair a 3745/3746 hardware failure.

 Remember that the 3745/3746 are machines which are designed to be repaired while the cus-

tomer is still using the operational areas. This is called Concurrent Maintenance. Before changing FRUs, you will be directed to ensure that you have the correct area of the machine ready for maintenance.

 When a power supply is shared between adapters, the disabling procedures apply to both 'sus-

pected' and 'associated' adapters.

 During a call for service, it will normally be necessary to use the 3745 console. To log ON at a

3745 console, proceed as directed in “Console Use for Maintenance.”

Console Use for Maintenance

001

Is the 3745 a Model 17A? Yes No

002

The 3745 is a Model 130, 150, 160, or 170.

The 3745 has password protection for functions controlled via a console. Several types of password exist for different activities. They are described in the SA33-0097.

Obtain the maintenance password from the customer so that you can log on at the 3745 console (local, remote, or alternate). This password will give you access to Menu 3 Maintenance Func- tions, in addition to Menu 1 and Menu 2. If the 3745 failure prevents correct operation of the 3745 console, continue at “Selection Table” on page 1-4 .

Log ON at the 3745 console as follows:

1. Ensure that the customer is not using the console and that he has logged OFF. The channel enable/disable screen is displayed.

2. Press F4: MOSS FUNCTIONS.

3. The password screen is displayed.

4. Enter the maintenance password.

Note: Remember to log OFF the console and to re-IML the MOSS at the end of the service call. See “CE Leaving Procedure” on page 4-102 for more information.

Continue with “Selection Table” on page 1-4.

Problems During Machine, EC, or MES Installation

When installing a 3745, the an MES, the supplied instructions should be used. It is possible that the task or diagnostic you were asked to perform during the installation detected an error, and you were requested to start troubleshooting using this manual.

The primary purpose of this manual is to resolve problems that occur in an operational environment after a successful installation. That is, the machine has worked previously and is now failing.

At installation time, or after an EC or MES is installed, it is possible that errors may occur due to conditions which would not exist in an operational environment.

 Cables plugged incorrectly

 Terminators missing

 Mismatch between CDF and machine configuration  Mismatch between line characteristics and setups  Wrong address set  Top card connectors incorrectly installed

 Loose cards. During your path through the MIP, you should remember these possibilities and, when the failing area is

identified, check with the aid of the that these conditions do not exist prior to changing FRUs.

Chapter 1. START: How to Begin Troubleshooting 1-13

Reference Codes

Using Reference Codes

Reference Codes (8 digits) are always displayed at the rightmost position of the alarm on the 3745 console. They are generated by the microcode which runs within the MOSS to provide an automatic analysis of box event records (BERs). This function is known as auto-BER and is part of the AUTOMAINT facility. Reference codes are also generated when diagnostics detect an error.

If several alarms have been generated for the same problem, resulting in multiple reference codes, use the reference code beginning with BX, if any. If there are no BX codes, use the reference code given by the earliest alarm.

To analyze a reference code to find the correct action to take, use the following procedure on the 3745 console:

1. From the Maintenance Functions on Menu 3, select the BRC function. The reference code screen will be displayed (see Figure 1-1).

REFERENCE CODE INTERPRETATION

2. Type in the 8-digit reference code you want to analyze in the input area of the screen. Refer to Figure 1-1.

3. Press SEND the action you are required to perform will appear on the screen.

Note

When the microcode is a possible cause of the error, it is recommended that you check:

1. If you have the highest level of microcode for your machine.

2. That any applicable MCFs are installed.

Your support structure will have this information.

4. Hit F6 for additional information (on associated components and customer resources for TSS, HPTSS and ESS), and record the data for later usage.

Note: If the CDF is not correct, this information can be wrong.

5. When the FRU list is given, record the types and location, then use the “3745 FRU List” on page 1-53.

If the reference code is reported as 'INVALID' or 'DUMMY', check that you have entered the same code as reported. If so, an error in the BER analysis or BER logging has occurred. Contact your support structure for assistance. See “Contacting Support” on page A-1.
