23-S FCH Failure Notification (Detection)

6.2Repair Procedure

13-I (Temporary)

STEP 1: Make sure that the front cable is securely inserted. (See Figure 7-10.)

STEP 2: If this message has been displayed once or twice, monitor the failure for a while. Otherwise, move to STEP 3.

STEP 3: If 13-J (Recovery) has been displayed after this message, monitor the failure for a while. Otherwise, move to STEP 4.

STEP 4: Initialize the indicated FCH (PA-FCHA) card using the MB key. (MB key: Down Up Down)

See Figure 7-3. When the LED on the FCH card lights green and the related system messages are not displayed any more, monitor the system for a while. Otherwise, move to STEP 5.

STEP 5: Replace the FCH card, following the procedure listed in Figure 7-4. If the failure exists after card re- placement, move to STEP 6.
