If the alarm recurs, check that the following cables and connectors are connected and fully inserted. • Cable for connector CN231/232 on the ASF04 board • Cable for connector CN239/240 on the ASF04 board • Cable for connector CN113 on the AIF01 board |
| ASF04 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the ASF04 board. Save CMOS.BIN before replacing the 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. |
