ECA 048 - 8580 system board + Busmaster
ECA 048 - 8580 system board + Busmaster
Provide a replacement system planar for certain 8580's
PURPOSE:
To provide a replacement system board 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 in the eligible serial numberrange with system
board FRU (field replaceable unit) P/N 33F8415 or FRU
P/N 90X7390 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/N 33F8415 or
P/N 90X7390, this ECA is not applicable.
PREREQUESITES:
Any one of the following conditions:
- an eligible Busmaster currently installed in the system.
- when an eligible Busmaster is on order to be installed in
the future.
- optionally, at customer request, if an eligible Busmaster
is to be installed in the future.
- installation in systems currently in dealer inventory if it
is to be configured with an eligible Busmaster.
DETAIL:
Only 20 MHz models (8580-111, 311, 121 and 321), which have
system board FRU P/N 33F8415 or P/N 90X7390 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:

The following Busmaster is currently under review and may or
may not require this engineering change. As a pre ECA: utionary
measure, it is considered eligible for ECA:048 unless otherwise
notified by IBM or the manufacturer.

As of the above date, any other currently shipping Busmaster
adapters listed in the IBM Micro channel catalog (G360-2824-04)
will not be affected and are not eligible for replacement.
IBM will continue to monitor future Busmaster releases, and will
update this listing as required.
NOTEs:
Replacement system board FRU P/N 85F0434 should be ordered
using normal FRU parts ordering procedures. All orders for
FRU P/N 33F8415 and FRU P/N 90X7390 will be automatically
substituted to the current FRU part number.
