C/CON or EPC/CON hangs at P1 when power-cycled. C/CON or EPC/CON hangs at P1 when power-cycled.
Symptom: When the concentrator powers up, it gets to P1 and just hangs there.
Cause:
- The concentrator is not getting the initial signal from the host adapter because it is not connected at all, or it is connected on the wrong line.
- The driver is not installed or the concentrator that is configured does not match the actual physical concentrator type.
- The timing on the host adapter and/or the concentrator and/or the modems is set incorrectly.
- The host adapter is malfunctioning.
Solutions:
Verify that the cables are all connected securely and that the concentrator is attached to the correct line.
Check to make sure that the operating system has been updated with all service packs/patches installed, the latest version of the driver is installed and loading correctly, and that the correct type of concentrator is configured.
Verify the timing settings on the host adapter, the concentrator, and the modem.
Run the appropriate diagnostics on the adapter board for the card and bus type.
