Subject: ECA Riser Card - M/Ts 6577/87/89, 6877/87, 8639
SIGNAL QUALITY CONDITION with PCI TOKEN RING ADAPTER
AS REQUIRED: CDT PC300/700 6577/87/89, 6877/87 with PCI T/R Adapter.
MANDATORY: ALL PC SERVER 310 166MHz = 8639 Mod 0E0,0EV,0EB.
Dealers should order all needed riser cards (CDT and Server) via UPOS.
SYMPTOM: The condition can potentially cause a data error that could
manifest itself in a system hang, or result in incorrect data with or
without generating an error message.
PROBLEM: Server 310 166MHz and PC 300 Series 6577 and 6587 systems may
experience the signal quality condition when used in conjunction
with either of the following IBM PCI network adapters as listed below.
FIX: Replacement of the Riser Card to eliminate a potential signal
quality condition which may occur during file transfer in these
systems, for PC300/700 only if it contains one of the Token-Ring
adapters listed below.

CIRCUMVENTION / DETAIL INFO
SERVER 310 166MHz
Replace the riser card in 8639 Models 0E0, 0EV and 0EB. System manufac-
tured after May 1, 1997 (MFG DATE: 705 and later on the rear serial
number label) are NOT affected.
Replace the riser card if BOTH the following conditions are met:
1) PC 300 Series 6577 or 6587 or PC 700 Series 6877 or 6887 with a riser
card matching the part number as stated in the table as listed above.
2) The system contains an IBM PCI Auto LANStreamer Token
Ring Adapter or an IBM PCI Token Ring Adapter as stated above
After installing the new riser, place a small white label approximately
1 centimeter in diameter on the machine type/model label on the rear of
the system unit. Please obtain a supply of stickers locally. Remarketers
should also place a sticker on the external shipping label attached to
the box as well as on the rear of the updated system unit. Use the
sticker attached to the rear of the system unit as a means for the
customer or servicer to identify updated systems prior to an on-site
No other combination of IBM or non-IBM PCI network adapters and
the PC 300 Series systems or Servers have exhibited this problem.
EC_TEST.EXE -> Tests the computer (DOS or OS2/W95/NT-DOS-Box) if
1. It is one of the affected models,
2. If yes, also for the presence of one the affected T/R Adapters.
It does not verify the level of the riser card itself.
This file is available on Internet at:
Placement of PCI adapters, especially PCI network adapters
of any brand, should be done beginning with the PCI slot
at the base of the riser card, closest to the system board.
Additional PCI adapters should be installed in a bottom to top
Customers exposed to this potential condition should place the IBM PCI network
adapter in the slot closest to the system board until the new riser card has been
installed. This will minimize the possibility of this condition.
