IBM ValuePoint - 64xx PCI riser installation and diagnostics
Applicable to: World-Wide
Service Information:
PCI RISER INSTALLATION
When installing a PCI riser card in ValuePoint Performance Series systems, do NOT plug anything into the 6-pin power supply type connector (J8) on the PCI riser card. This connector is for future expansion. Installing power supply connector P3 into this connector will prevent the system from powering up.
When the PCI riser card is removed from the system board, the system will not power up unless the 3 PCI jumpers on the system are installed in the VESA (rear) position. There is a jumper on the PCI riser card that must be set to match the speed of system board. Systems with the PCI riser card installed must be at flash level 53 or higher.
DIAGNOSTICS
Advanced Diagnostics and QA-Plus do not provide unique error codes for riser card failures and may report a bad system board when the failure is in the PCI riser. To isolate this failure, remove the PCI riser, move the PCI jumpers to VESA, and run diagnostics. If diagnostics now complete without error, do not replace the system board; replace the PCI riser.
ERROR CODES
Post Error Description Probable Cause
1800 PCI interrupt conflict Setup
1801 PCI ROM memory conflict Setup
1802 PCI I/O address conflict Setup
1803 PCI memory conflict Setup
(above 1mb)
1804 PCI memory conflict Setup
(1mb or below)
1805 PCI ROM memory error Defective PCI adapter
REPAIR ACTIONS
Insure that there are no interrupt or memory conflicts before replacing any hardware. Refer to the documentation provided by the option adapter(s) for installation, configuration, and adapter problem solving information. Due to setup and other interactions between adapter cards it is often necessary to diagnose adapter problems with only one adapter installed at a time.
The appropriate FRU/ACTION for 18xx error codes or other problems suspected to be either the PCI riser card or PCI adapter(s) are as follows :
1. Ensure the PCI riser card speed jumper is in the 40/50mhz position for 40 and 50 mhz systems and in the 25/33mhz position for 25 and 33mhz systems.
2. Ensure the 3 PCI jumpers on the system board are installed in the PCI (front) position.
3. Ensure the riser card and any adapters are completely seated in the appropriate connectors.
4. If the 18xx error can be eliminated by removing a PCI adapter, replace the adapter.
5. Replace the PCI riser.
6. Replace the system board.
