13-H/I/J Signaling Link Failure (Permanent)/(Temporary)/(Recovery)
6.1 Repair Procedure
13-H (Permanent)
STEP 1: Make sure that the front cable is securely inserted. See Figure 7-10.
Figure 7-10   FCH-DTI Connection
STEP 2: 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 anymore, monitor the system for a while. Otherwise, move to STEP 3.
STEP 3: Replace the FCH card, following the procedure in Figure 7-4. If the failure exists after card
replacement, move to STEP 4.
STEP 4: Replace the front cable labeled 10AL (10) FLT CA, since the cable is suspected as faulty.
6.2 Repair 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 the card
replacement, move to STEP 6.
STEP 6: Replace the front cable labeled 10AL (10) FLT CA, since the cable is suspected as faulty.
7. 23-S FCH  Failure Notification (Detection)
This message is displayed when the FCH (PA-FCHA) card is faulty due to the phenomenons such as an ETHER
controller initial failure.
The message is displayed in the following format. If this message is displayed, check the related ETHER cables,
following the procedure listed on the next page.

23-S FCH Failure Notification (Detection)
7.1 Repair Procedure
STEP 1: Make sure that the related Ethernet cables are securely inserted into the connectors. See Figure 7-12.
If not, securely insert the cable and confirm whether System Message 23-T FCH Fault Recovery
Notification is displayed as the result of cable insertion. If no fault is found in this step, move to STEP
2.
STEP 2: The following equipment is suspected to be faulty. Check for each item:
Ethernet cables (10 BASE-T cables)
 ← See Figure 7-13 “How to Check 10 BASE-T cables.”
HUB (PA-M96) 
← See Figure 7-14 “How to Replace HUB (PA-M96) card.”
