8573 STATIC SUPPRESSING DISKETTE DRIVE COVE

PURPOSE:
PURPOSE: TO PREVENT STATIC DAMAGE TO AN 8573 SYSTEM WITH A SERIAL NUMBER OF 49,999 OR EARLIER, REPLACE THE DISKETTE DRIVE COVER IDENTIFIED IN THE PHYSICAL CHECK SECTION OF THE ECA WITH A RE-ENGINEERED DISKETTE DRIVE COVER FRU P/N79F3239.

Machines Affected
8573	MOD 031 BELOW XX49999
8573	MOD 061 BELOW XX49999
8573	MOD 121 BELOW XX49999

PHYSICAL CHECK:
REMOVE THE DISKETTE DRIVE COVER ON SYSTEMS WITH SERIAL NUMBERS BELOW 49,999 AND CHECK FOR A METALIZED COATING ON THE INSIDE OF THE DRIVE AREA WHERE THE DISKETTE OPENING IS LOCATED. COVERS WITH A COATING IN THIS AREA SHOULD BE REPLACED WITH THE NEW LEVEL OF DISKETTE DRIVE COVER.

REQUIRED IF SOLID OR INTERMITTENT POST HANGS OCCUR WITH A SOLID POWER AND DSKT LIGHT.

DETAIL:
STATIC FROM A PERSON INSERTING A DISKETTE INTO THE DISKETTE DRIVE CAN CAUSE A SYSTEM BOARD GATE ARRAY TO FAIL OR BE DAMAGED. THIS WILL CAUSE SOLID OR INTERMITTENT POST HANGS TO OCCUR WITH A SOLID POWER AND DISKETTE DRIVE LIGHT ON. IF THE COVER HAS A METAL COATING ON THE INSIDE WHERE THE DISKETTE PASSES THROUGH, REPLACE THE OLD LEVEL DISKETTE DRIVE COVER WITH THE NEW COVER, FRU P/N79F3239. IF THE SYSTEM IS ALSO EXPERIENCING A POST HANG CONDITION USE ECA062 TO INSTALL A SYSTEM BOARD. CHECK THE MODEL AND SERIAL NUMBER OF THE SYSTEM TO DETERMINE THE SYSTEM BOARD FRU NUMBER.

NOTES:
THIS ECA DOES NOT APPLY TO 8573 P70 SYSTEMS ABOVE SERIAL NUMBER 50,000 BECAUSE THEY ARE NOT SUBJECT TO THIS TYPE OF STATIC DISCHARGE.
