ECA048 - 8580 System board & Busmasters

REPLACE SYSTEM BOARDS FOR SOME 8580 MODELS 111, 311, 121 AND 321 WHICH HAVE BUSMASTER * ADAPTER(S)

PURPOSE:
REPLACE SYSTEM BOARDS FOR SOME 8580 MODELS 111, 311, 121 AND 321 WHICH HAVE BUSMASTER * ADAPTER(S) INSTALLED DUE TO A POTENTIAL DATA LOSS PROBLEM.

* BUSMASTER ADAPTERS USUALLY CONTAIN A MICROPROCESSOR AND HAVE THE CAPABILITY OF CONTROLLING DATA TRANSFER ON THE MICRO CHANNEL BUS, INDEPENDENTLY OF THE SYSTEM MICROPROCESSOR. DUE TO VARIATIONS IN DESIGN, VISUAL IDENTIFICATION OF A BUSMASTER MAY BE DIFFICULT, THEREFORE THE DOCUMENTATION ACCOMPANYING THE ADAPTER IN QUESTION SHOULD BE REFERENCED.

PHYSICAL CHECK:
8580'S IN THE ELIGIBLE SERIAL NUMBER RANGE WITH SYSTEM BOARD FRU (FIELD REPLACEABLE UNIT) P/N33F8415 OR FRU P/N90X7390 LOCATED NEAR THE EDGE OF THE SYSTEM BOARD BY THE MICRO CHANNEL SLOTS, OR THOSE BOARDS WHICH ARE NOT IDENTIFIED WITH A VISIBLE FRU PART NUMBER. IF ANY FRU PART NUMBER IS VISIBLE, OTHER THAN P/N33F8415 OR P/N90X7390, THIS IS NOT APPLICABLE.

PREREQUISITES:
ANY ONE OF THE FOLLOWING CONDITIONS:

AN ELIGIBLE BUSMASTER CURRENTLY INSTALLED IN THE SYSTEM.
N AN ELIGIBLE BUSMASTER IS ON ORDER TO BE INSTALLED IN THE FUTURE.
ONALLY, AT CUSTOMER REQUEST, IF AN ELIGIBLE BUSMASTER IS TO BE INSTALLED IN THE FUTURE.
TALLATION IN SYSTEMS CURRENTLY IN DEALER INVENTORY IF IT IS TO BE CONFIGURED WITH AN ELIGIBLE BUSMASTER.

DETAIL:
ONLY 20MHZ MODELS (8580-111, 311, 121, & 321), WHICH HAVE SYSTEM BOARD FRU P/N33F8415 OR P/N90X7390 INSTALLED, MAY EXHIBIT THIS PROBLEM.

SYSTEMS WITH THE AFFECTED SYSTEM BOARDS MAY EXHIBIT VARIOUS SYMPTOMS, OR NO SYMPTOMS AT ALL, DEPENDENT ON THE ACTUAL BUSMASTER ADAPTER INSTALLED.

8580 SYSTEMS WHICH MEET THE PHYSICAL CHECK REQUIREMENTS AND HAVE INSTALLED, OR ARE PLANNING TO INSTALL, ONE OR MORE OF THE FOLLOWING BUSMASTER ADAPTERS, ARE ELIGIBLE FOR SYSTEM BOARD REPLACEMENT:
