Issue Description: 

If an AC power sequencer fails in an E10000 with two unipacks as boot
devices for the same domain and powered by the same AC power sequencer,
the domain will crash and will remain unbootable until the power sequencer 
is replaced or the power cable on one of the unipack boot devices is 
moved to another power sequencer.

Even though E10000 systems are shipped with two AC power sequencers 
installed, both the primary and alternate boot devices for each domain
can be configured to receive power from the same sequencer, creating
a single point of failure.
 
E10000 systems which are ordered with unipacks for boot devices must be 
configured redundantly in terms of power.  The primary and alternate
boot devices should receive power from two different sources (i.e. two
different AC power sequencers).  The SSE installing the system should
insure that this is done at install time.

Since there are 256 different possible combinations of unipack to
board connections, Sun Manufacturing is not able to make the
power connections recommended above during system assembly.

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.

When SSE's install a new E10k and set up domains, visually inspect the
power connections from the 2 unipack boot devices for each domain to
insure that the primary boot device and the secondary boot device are
not plugged into the same AC power sequencer.  If both unipacks are 
connected to the same power sequencer, the power cord from one of the 
units should be moved to the second power sequencer, eliminating
the single point of failure.

Comments: 

Note: Even though not recommended, the E10k can be ordered in
      configurations that have only one AC Power Sequencer installed.
      In this case the boot devices (Unipacks, D1000, RSM) are plugged
      into the same AC power sequencer.  If the E10K is shipped with
      two AC power sequencer and the factory configured domains are
      connected to redundant UniPacks, these are always powered by
      different AC power sequencer.  In case of a D1000, the redundant
      D1000 power supplies are connected to different AC power
      sequencers.  

      If domains on the E10K are reconfigured in the field, make sure
      that two UniPacks for the same domain are not connected to the
      same power source.

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.
