INTRODUCTION

THIS MANUAL CONTAINS THREE PARTS:

1. INTRODUCTION - WHICH DEFINES THE CONTENT OF THE MANUAL AND EXPLAINS HOW TO USE IT.

2. RESERVED FOR FUTURE USE.

3. TU COMPATIBILITY - WHICH CONTAIN THE PART NUMBER COMPATIBILITY PAGES FOR THE TAPE UNIT (TU).

DOWNWARD COMPATIBLE: A NEW ASSEMBLY (USUALLY A HIGHER PN) IS A DIRECT REPLACEMENT (DOWNWARD COMPATIBLE) FOR AN OLD ASSEMBLY (USUALLY A LOWER PN) WHEN IT DOES NOT DEGRADE MACHINE

PERFORMANCE. DOWNWARD

COMPATIBILITY IS INDICATED WHEN BOTH ASSEMBLIES HAVE THE SAME COMPATIBILITY NUMBER.

UPWARD COMPATIBLE: AN OLD ASSEMBLY (USUALLY A LOWER PN) IS EQUIVALENT TO (UPWARD COMPATIBLE) AND MAY DIRECTLY REPLACE A NEW ASSEMBLY (USUALLY A HIGHER PN) IF ITS USE DOES NOT AFFECT MACHINE PERFORMANCE.

UPWARD COMPATIBILITY IS INDICATED WHEN ASSEMBLIES HAVING THE SAME COMPATIBILITY NUMBER ARE ALSO INDICATED AS "EQUIVALENT" IN THE

"DESCRIPTION OF EC" FIELD.

EACH PAGE IN THE COMPATIBILITY SECTION CONTAINS THE COMPATIBILITY INFORMATION FOR A SINGLE CARD TYPE. IT SHOWS THE HISTORY OF ENGINEERING CHANGES (EC'S) THAT RESULTED IN PART NUMBER CHANGES FOR THAT CARD. IT ALSO SHOWS WHICH PART NUMBERS ARE OBSOLETE AND WHAT PART NUMBERS CAN BE USED TO REPLACE THEM.

FOR SOME CARDS, THE FUNCTIONAL CHANGES THAT RESULTED IN NEW PART NUMBERS WILL NOT FUNCTION WITHOUT CORRESPONDING MACHINE REWORK. THIS USUALLY RESULTS IN A COMPATIBILITY NUMBER

C\

CHANGE FOR THE NEW ASSEMBLY. THE "DESCRIPTION OF EC" FIELD WILL SUMMARIZE THE CHANGES. THE FIELD APL

DEFINI~G

THE REQUIRED REWORK WILL BE LISTED IN A SEPARATE COLUMN NEXT TO THE EC NUMBER.

IF THE COMPATIBILITY NUMBER DOES NOT CHANGE, THE NEW CARD WILL PERFORM AT LEAST THE SAME FUNCTIONS AS THE OLDER CARD.

COMPATIBILITY AND OBSOLESCENCE

ANY PART NUMBER THAT IS PREFIXED WITH AN ASTERISK (*) IS AN OBSOLETE PART NUMBER. OBSOLETE MEANS THAT THE PART WILL NO LONGER BE SUPPLIED. IF AN OBSOLETE PART IS ORDERED, THE FIELD PARTS CRIB WILL SUBSTITUTE A PART THAT IS DOWNWARD COMPATIBLE OR EQUIVALENT TO THE PART NUMBER ORDERED.

FOR SOME CIRCUIT CARDS, ALL PART NUMBERS OF THE CARD AT A PARTICULAR COMPATIBILITY NUMBER HAVE BEEN OBSOLETED, LEAVING NO AVAILABLE REPLACEMENTS AT THAT COMPATIBILITY NUMBER.

THIS SITUATION OCCURS WHEN A CARD IS OBSOLETED BY A MANDATORY EC. IF A REPLACEMENT IS ORDERED FOR AN OBSOLETE CARD FOR WHICH THERE IS NO REPLACEMENT AT THE COMPATIBILITY NUMBER, IT IS POSSIBLE THAT ONE OR MORE MANDATORY EC'S ARE MISSING FROM THE MACHINE. CHECK THE EC HISTORY LOG FOR THAT MACHINE, AND THE COMPATIBILITY PAGE FOR THAT CARD FOR

"DESCRIPTION OF EC" AND THE APPLICABLE APL NUMBERS. UPDATE THE MACHINE SUCH THAT A REPLACEMENT CARD OF A HIGHER COMPATIBILITY NUMBER CAN BE USED. (IT MAY BE NECESSARY TO ORDER THE INDICATED APL WHICH WILL PRODUCE THE CORRECT CARD NEEDED).

DOWNWARD COMPATIBILITY IS DESIGNATED BY THE COMPATIBILITY NUMBER TO THE RIGHT OF THE PART NUMBER. A CARD OF A GIVEN PART NUMBER IS DOWNWARD COMPATIBLE WITH ALL THOSE LOWER PART NUMBER CARDS THAT HAVE THE SAME COMPATIBILITY NUMBER. THIS MEANS IT CAN BE USED TO REPLACE ANY OF THE LOWER PART NUMBER CARDS HAVING THE SAME COMPATIBILITY NUMBER WITHOUT REQUIRING REWORK TO THE CARD OR MACHINE.

*42150203 2 ADD REWORK. 40050

REQUIRED MBD AT LEVEL

42150204 2 ADD REWORK 40060

IN THE ABOVE EXAMPLE:

PIN 42150 101 CAN REPLACE ONLY ITSELF.

PIN 42150 102 CAN REPLACE ITSELF OR PIN 42150101 (OR -202 BECAUSE IT IS EQUIVALENT).

pIN 42150 202 CAN REPLACE ITSELF, PIN 42150101 OR PIN 42150102.

PIN 42150 203 CAN REPLACE ONLY ITSELF. (CAN NOT REPLACE LOWER LEVEL CARDS UNLESS MBD CHANGE OR OTHER PREREQUISITE IS INSTALLED).

PIN 42150 204 CAN REPLACE ITSELF AND' -203. (CAN NOT REPLACE LOWER LEVEL CARDS UNLESS MBD CHANGE OR OTHER PREREQUISITE IS INSTALLED).

* THE ASTERISK TO THE LEFT OF A PART NUMBER INDICATES THAT THE PART IS OBSOLETE AND IS NO LONGER SUPPORTED BY MANUFACTURING. THE HIGHEST LEVEL PART FOR EACH COMPATIBILITY LEVEL SHOULD NOT CARRY AN ASTERISK BECAUSE MANUFACTURING MUST SUPPORT FIELD SPARES UNTIL ALL MACHINES HAVE BEEN BROUGHT TO THE NEXT COMPATIBILITY LEVEL.

CAUTION

UPWARD COMPATIBILITY EXISTS ONLY IF TWO CARDS WITH THE SAME COMPATIBILITY NUMBER ARE DESCRIBED AS "EQUIVALENT" IN THE

"DESCRIPTION OF EC" FIELD. ANY OTHER SUBSTITUTION OF A LOWER PART NUMBER CARD FOR A HIGHER PART NUMBER CARD REQUIRES A GREAT DEAL OF CAUTION. SUCH PRACTICE MAY RESULT IN NOISE PROBLEMS, TIMING PROBLEMS, DIAGNOSTIC ERRORS, ETC.

ANY ATTEMPT TO UTILIZE SUCH A LOWER PART NUMBER CARD REQUIRES ENSURING THAT FUNCTIONAL CHANGES OR IMPROVEMENTS MISSING FROM THE LOWER PART NUMBER CARD WILL NOT RESULT IN CUSTOMER SYSTEM OPERATION DEGRADATION. REFERENCE THE DESCRIPTION OF EACH CHANGE MISSING FROM THE CARD AND ENSURE THAT NO MACHINE WIRING CHANGES OR COMPANION CHANGES TO OTHER CARDS WERE REQUIRED AT THE TIME THE HIGHER PART NUMBER WAS INSTALLED ORIGINALLY. USAGE IN THIS MANNER IS NOT RECOMMENDED AND SHOULD BE AVOIDED IF POSSIBLE.
