Issue Description: 
EMI cap screws on PCI Cassettes in Sun Fire 12K/15K platforms may tighten 
over time, making it difficult to remove I/O adapter cards.  The issue may 
be encountered if it is necessary to remove the EMI cap from a cassette in 
order to replace a faulty cassette, replace a defective I/O card, or to 
upgrade an I/O card.  There is no impact to a running system. 

This issue occurs because the two M3x5 screws securing the EMI cap can become 
excessively tight.  Attempted removal of the screws may result in damage to 
the heads of the screws, rendering the cassette useless.  If this occurs, the 
cassette would need to be replaced.   

This issue occurs due to a reaction between dissimilar materials that causes 
the torque of the screws to increase over time.  The reaction is between the 
zinc screws and a cosmetic film on the casting of the cassette.

The issue was originally resolved in manufacturing by reducing the torque 
value of the screws and was permanently solved via ECO WO_28346 by changing
the screw material to stainless steel.
Implementation: 
---
|   |   MANDATORY (Fully Pro-Active)
 ---

 ---
|   |   CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
 ---

 ---
| X |   UPON FAILURE
 ---
Replacement Time Estimate: 
1.0 hours
Special Considerations: 
This FCO will have a time zone phased release based on material
readiness as follows:

                   Readiness Date         
                   --------------         
   US/Canada       Jan/30/2005    
   Ltn America     Jan/27/2005      
   EMEA            Dec/12/2004                                                                                   
   APAC            Jan/30/2005            
   Japan           Jan/27/2005     

The above dates represent when each time zone has determined that
it will be materially ready to support this FCO.
Corrective Action: 
Replace 501-5600-08 (or lower) with 501-5600-09 (or higher) 
or with 501-5600-xx having DPCO 477 label.

Replace 501-6086-04 (or lower) with 501-6086-05 (or higher) 
or with 501-6086-xx with DPCO 477 label.

If this issue is seen while attempting to remove the EMI cap from an affected 
cassette, the following actions should be taken:

1. Attempt to remove the screws from the EMI cap:

    - Place the cassette onto a hard surface.

    - Using a Phillips #1 driver that fits snugly into the screw, press down 
      firmly while unscrewing.

    - If the screw on the first side does not break free, try the screw on the
      other side, as this may make a subsequent attempt successful.

2. If the above fails and the head of the screw is destroyed:

    - The cassette should be replaced per this FCO.

    - Attempt to remove the I/O adapter card from the cassette.  To accomplish 
      this, move the cassette to an acceptable location and and attempt to 
      drill out the head of the screw or use a screw extraction bit.  The old 
      cassette should be considered scrap.
      
    - If it is not possible to remove the I/O card from the cassette via the
      previous step, return the entire unit (cassette + I/O card) for repair.


Note: This issue will only be encountered during ongoing maintenance activity.  
      All procedures in the Sun Fire 12K/15K Systems Service Manual, 
      P/N 806-3512-12, Section 9.2, should be closely adhered to.
Comments: 
None.
