A test failure during Phase 1 most likely indicates a problem with the CHANNEL adapter installation. Test status messages may lead you directly to the problem. You also can check the following conditions:
Is there an IRQ Acronym for interrupt request. The hardware line over which the processor and adapter communicate conflict with another adapter? If so, follow the instructions in the BARR/CHANNEL-IN manual to reset the IRQ.
Is the adapter installed correctly? Make sure the adapter is seated firmly in the slot.
Is the adapter making a clean connection? Try cleaning the adapter’s gold-plated fingers with a pencil eraser.
Are there bent pins on the serpentine connectors In hardware, the couplers used to join cables or to join cables to devices.? Gently straighten the pins.
You can also view the System Event log. It contains information about the software events surrounding adapter and driver installation. Use the Windows Event Viewer to view the Event log.
