Alarm Level: Major

Recovery

1. Locate the fuse and alarm panel (FAP) indicated in the alarm message.
2. Look at the set of fuses and find the fuse with the “flag” standing out.
   This indicates the fuse is blown. Replace the fuse with a GMT 3 amp or 1 amp (depending on the type being replaced). See the Installation Manual for the correct fuse type.

   Caution:

   Arbitrarily removing a good fuse will cause all cards serviced by the removed fuse to fail. Verify the fuse output before pulling a fuse that appears to be good.
3. If no fuses appear to be blown, use a VOM and measure the voltage outputs on the rear of the panel (refer to the Installation Manual for voltage test points).
4. If the fuse blows again, visually inspect the shelf backplanes for shorts or metallic debris.
5. If nothing can be found visually, put all cards serviced by the affected fuse out of service with the following command:
   rmv-card:loc=x

   where x is the card location stenciled on the shelf of the system.

6. Unplug the cards serviced by the affected fuse.
7. Replace the fuse.
8. Plug in each card one at a time.
   As each card is plugged in, verify the fuse does not blow. When the fuse does blow, replace the card just plugged in.
9. Replace the fuse again.
10. Continue plugging in the remaining cards, verifying the fuse does not blow with each card.
    Each time the fuse does blow, replace the card and continue. There may be more than one card at fault. If you encounter a card which blows the fuse, do not stop the procedure. Continue until all cards have been plugged in. Refer to the Maintenance Manual for card removal/replacement procedures.
11. If all the cards are plugged in and the fault has cleared, place the affected cards back into service by entering the following command:
    rst-card:loc=x

    where x is the card location stenciled on the shelf of the system.

12. If this does not clear the fault, contact My Oracle Support (MOS).
