USING THE IBM 5110 SYSTEM MAPS

MAPs

The MAPs guide you through the service call using step-by step procedures that require you to follow trace lines when responding to questions or when leaving or entering a page. The MAPs use a logical approach for isolating the possible causes of machine problems and point you to that part of the 5110 that requires adjustment or replacement.

Two types of MAPs are used in the 5110 maintenance library. First, there are the hard-copy (printed) MAPs within the MLM binder. These MAPs are contained in a separate removable binder. The second type of MAP is the MOl (MAP diagnostic integration). These MAPs are located on the diagnostic tape/diskette and are shown on the display screen. The system automatically pages through the MAPs when you respond to the questions on the display.

Other Reported Fail u res ------f..------1~O-~L-______~

NoSymptoms------+------,

Begin each call with Start MAP 200. This MAP ensures that the system is operating sufficiently to use other MAPs or MDls.

Start MAP 200 asks you to record the status bytes, error logs, and history logs because this information is lost on power down or RESTART. The Start MAP either fixes or directs you to a MAP that tells you how to fix any of the following problems: I ndi cator lights Bring up failures Process checks Display failures For other failures, the Start MAP directs you to the correct MAP through an error code. If you are certain the failure is not covered in the Start MAP, you can go directly to the other MAPs indicated by the ® in the chart.

All MDls have a MAP as an entry. For example, MAP 810-5103 is an entry for MOl 800 through 805. These MAPs provide the setup instructions for running the MDls.

The MDls are a combination of MAPs and diagnostics. The MD Is call in and run the appropriate diagnostics and answer most of the MAP questions automatically.

The procedures for diagnosing intermittent failures contain a more detailed description of what part of the system each MOl checks. USING THE MAPS (.~.\ When using the MAPs, you must: I READ CAREFULLY. The MAPs can help you find the problem only if you follow instructions and answer questions accurately.

FOLLOW THE SEQUENCE. Proceed step-by-step at all times. At times, the MAP instructions might seem irrele -vant. However, they can be important in determining the correct error indications.

FOLLOW INSTRUCTIONS. Instructions must be carried out exactly in the order given. Questions are based on instructions immediately preceding the questions. Do not change the conditions established by the instructions before answering the questions. Do not press the RESTART switch until you are told to do so in the MAPs.

When you are asked to probe a line in the MAPs, the line name and its active level are given. For example:

- Probe H2-G06 (- machine check).

The - (minus) in front of machine check indicates that this line is active at a down level.
