IBM PC750 - Hangs when fully populated with adapters
Applicable to: World-Wide
Sympton:
IBM PC 700 Series 6885 systems may exhibit intermittent or solid system hangs during IPL or after running normally for 30 minutes or more.
Problem Isolation Aids:
Intermittent or solid system hang conditions in PC 700 6885 systems may be the result of a fully populated riser card. For example, if the user has installed the following adapters, hangs may occur during boot or after the system has warmed up:
Riser Slot 1 (bottom) = 3270 Adapter
Slot 2 = WAC Adapter
Slot 3 = Token Ring Adapter
Slot 4 = Empty
Slot 5 = SCSI Adapter
Note:
A fully populated riser card in a 6885 contains 4 adapters.
Fix:
If the system is exhibiting the failure stated above, and has a fully populated riser card with ANY combination of adapters, change the order of the adapters on the riser to eliminate the failure. For example, change the order of the adapters listed above to the following:
Riser Slot 1 (bottom) = WAC Adapter
Slot 2 = Token Ring Adapter
Slot 3 = 3270 Adapter
Slot 4 = Empty
Slot 5 = SCSI Adapter
If the failure persists, continue normal problem determination to isolate the failing part.
