H137633 - ECA010: PC SERVER 325/330 PROCESSOR CARD JUMPER J9
PURPOSE:
This ECA provides for the repositioning of Jumper J9 (I/O Queue
Depth) on the Pentium Pro processor card FRU p/n 75H7419.
The correct placement of the jumper can prevent traps, hangs,
and bus timeout errors during heavy CPU and I/O activity. This
symptom has been observed during heavy stress tests in a dual
Pentium Pro processor environment.
PHYSICAL CHECK:
- A DOS diskette utility named "4227122.EXE PC Server 325/330
IOQD Utility" will check the position of Jumper J9.
- Systems manufactured after May 1, 1997 (MFG DATE: 705 and
later on the rear serial number label) are NOT affected.
DETAIL:
Use the following procedure:
1. Download and expand 4227122.EXE (IOQD Utility) from the IBM
PC Company BBS/WEB.
2. Shutdown the operating system and boot the IOQD Diskette.
3. The IOQD Utility will check the current position of Jumper
J9 on the processor card.
4. If the J9 jumper is set correctly on pins 1-2, the Utility
will inform the operator that it is set correctly; proceed to
step 6.
5. If the J9 jumper is missing or is on pins 2-3, the Utility
will beep and inform the operator to move the jumper to
pins 1-2. A diagram will be displayed showing the correct
position of the J9 Jumper. Power off the Server, and move
the J9 jumper to pins 1-2. Jumper J9 is located behind
PCIset module U4. Refer to the diagram below.
Note: It is usually possible to move the J9 jumper without
removing the processor card or any adapters.
Do NOT change the position of Jumpers J10 and J12.
6. Remove the IOQD Utility Diskette and reboot the Server.
