11xx An error occurred during the system-board serial port test.
Action: If you have a modem, serial printer, or other serial device attached to your server,
verify that the serial cable is connected correctly. If it is, use the following
procedure:
1. Turn off the server.
2. Disconnect the serial cable from the serial port.
3. Wait five seconds; then, turn on the server.
If the POST error message does not reappear, either the serial cable or the device is probably
failing. See the documentation that comes with the serial device for additional testing
information.
If the POST error message reappears, call for service.

Action: 1. Make sure that the IRQ and I/O port assignments needed by the serial port are
available.
2. If all interrupts are being used by adapters, you might need to remove an
adapter to make an interrupt available to the serial port, or force other adapters
to share an interrupt.
1800 A PCI adapter has requested a hardware interrupt that is not available.
Action: 1. Make sure that the PCI adapter and all other adapters are set correctly in the
Configuration/Setup Utility program. If the interrupt resource settings are not

2. If all interrupts are being used by other adapters, you might need to remove an
adapter to make an interrupt available to the PCI adapter, or force other
adapters to share an interrupt.
