IBM ValuePoint - 5250 and other adapters may fail
Applicable to: World-Wide
Symptom:
Enhanced 5250 Display Station Emulation adapter (any level), and other adapters that require -5 volts from the system power supply, fail to function when installed in ValuePoint Performance Series machine types 6492 and 6494.
Problem Isolation Aids:
Inspect the three power supply cables with 6 pin connectors identified as P1, P2, and P3. These connectors are all keyed differently but can be forced into the wrong sockets. Connectors P1 and P2 should be plugged into the system board. If P3 is plugged into the system board where P2 should be installed, any adapter that requires -5 volts will fail. Power supply connector P3 is not used on these models. The VP system, and any adapters that do not use -5 volts will function as designed.
Fix:
Plug P1 and P2 into system board connector J1 per the connector keys. If problems persist, continue with normal problem
determination.
