Issue Description: 

Fiber channel devices may experience symptoms consistent with marginal
signal quality on the GBaud FC-AL loops.  Marginal signal quality can
be caused by dust particles and/or errant electrostatic discharge (ESD)
for GBIC's, backplanes, interface boards, GEM boards, interconnect
assemblies, FC-AL drives, and fiber cables.

Symptoms of errors that might be seen include:
    
    - excessive "CRC Error" or "scsi parity error" messages
    - excessive "OFFLINE" messages
    - excessive "timeout" messages
    - "Offline Timeout" messages 

These errors may be caused by a single dust particle interrupting
and/or interfering with an optical signal.  Likewise a component may be
damaged by unintended transmission of an ESD charge from the
maintenance person to the component.  To minimize the possibility of
failures from either an errant dust particle or ESD charge, ensure that
the handling guidelines provided in this FIN are followed.

Implementation: 

---
        |   |   MANDATORY (Fully Pro-Active)
         ---    
         
  
         ---
        |   |   CONTROLLED PRO-ACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   REACTIVE (As Required)
         ---

Corrective Action: 

An Authorized Enterprise Field Service Representative may avoid the
above mentioned problems by following the recommendations as shown
below.

To minimize the possibility of failures from either an errant dust
particle or errant ESD transmission, ensure the handling guidelines
provided in this FIN are followed for installing the new parts in
the field.

NOTE: Ensure that the person handling the device is following correct 
      ESD procedures to guard against the possibility of damaging the 
      device.  Using a working ESD wriststrap, avoiding contact between 
      the device and any clothing even when wearing the wriststrap etc.

NOTE: Also make sure to use the static mat P/N 250-1080-01 and attach 
      wrist straps for safety reason to follow an ISO9000 certified 
      way of handling of ESD product.

   1. Remove the fiber optical cable from either the GBIC, Host Bus
      Adapter, GEM-PCI or GEM-SBUS.

      When handling or installing fiber optic cables, do not exceed the
      minimum bend radius or exceed their maximum tensile load values.
      This means that they should not be kinked sharply or have a bend
      radius smaller than 30mm for standard Sun fiber cables.
      Furthermore, there should be no significant tension (i.e. 'pull')
      on the fiber cable - any tension has the effect of increasing the
      minimum allowable bend radius before damage occurs.

   2. Immediately place protective caps on fiber optic cable ends.

   3. With the protective cover installed, position the new GBIC, 
      Host Bus Adapter, GEM-PCI or GEM-SBUS for installation.

   4. Remove the failed GBIC or Host Bus Adapter.
      
      When storing a GBIC or when the GBIC is disconnected from a fiber
      optic cable, be sure to keep the dust plug over the GBIC's
      optical bores.  The Fiber Optical devices, including Host Bus
      Adapters, GBICs, GEM-PCI or GEM-SBUS are Electro Static Discharge
      (ESD) sensitive devices.

   5. Remove protective cover from new part, blow connector with 
      compressed gas, and install new part for either GBIC or Host Bus
      Adapter.  Use protective cover from new part and place on failed 
      part prior to returning part to vendor for repair for GEM-PCI or 
      GEM-SBUS.

   6. Remove protective caps from fiber optic cable, blow the fiber
      optic cable connectors with compressed gas and connect cable
      to the new GBIC or Host Bus Adapter.

   7. Place protective caps in clean bag and save for future
      maintenance activity.

Note: In this document, the term "Compressed Gas" will be used to refer
      to Specification:  1,1,1,2 - Tetrafluoroethane and Demethyl Ether
      compressed gas used for cleaning electronic devices .  (This product
      may be found at most electronic parts suppliers in spray can form.)

Implementation Footnote: 

i)   In case of MANDATORY FINs, Enterprise Services will attempt to    
     contact all affected customers to recommend implementation of 
     the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical    
     support teams will recommend implementation of the FIN  (to their  
     respective accounts), at the convenience of the customer. 

iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the   
     need arises.
