Turn the power OFF then back ON.
-If the error occurs again, remove the CF
card from the YCP21 circuit board and
reinstall it.
-If the error occurs again, replace the CF
card of YCP21 circuit board. After
replacing it, load the CMOS.BIN file
saved before the error occurs or
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *8)

-Turn the power OFF then back ON.
-If the error occurs again, remove the YIF
circuit board from the CPU rack and
reinstall it.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic

-Turn the power OFF then back ON.
-If the error occurs again, remove all the
circuit boards installed in CPU rack and
reinstall them.
-If the error occurs again though reinstall
them, replace the YCP21 circuit board.
After replacing the board, remove the CF
