ECA 070 - P70 Diskette Drive cover
8573 static suppressing Diskette Drive cover
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/N 79F3239.
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/N 79F3239. If the system is
also experiencing a POST HANG condition
use ECA 062 - P70 POST HANG 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.
Order parts through normal distribution channels.
