Description
The YRC1000 verifies that the I/O module which is detected during the startup is the same as the module set at the time of system configuration. This alarm occurs if the YRC1000 detects an error in the verification process.
Subcode description
The functions of the IO modules connected to PCI bus No. 3 do not match the configured IO module functions.
Causes and remedies
| Cause | Remedy |
|---|---|
| Software (incorrect setting) | Check the following settings. • PCI slot number in which each PCI board is installed • IO module setup in maintenance mode: Refer to the manual for each IO module for details of the configuration procedure. |
| Cable (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, check that the following connectors are connected and fully inserted. • PCI connector of the corresponding IO module |
| IO module (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the following boards. Save CMOS.BIN before replacing the board. • Corresponding IO module (PCI board) |
| AIF01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the AIF01 board. Save CMOS.BIN before replacing the board. After replacing the AIF01 board, load CMOS.BIN saved before the alarm occurred. |
| Other | If the alarm occurs again after implementing the countermeasures, contact our service department and describe the circumstances when CMOS.BIN was saved (operating procedure, etc.). |
