Issue Description: 

During the installation or upgrade of 400MHZ CPU Modules (X1194A)
of Sun Enterprise 250 systems, the CPU modules may become damaged
upon insertion into the plastic module guides.

This potential problem is due to a small number of Enterprise 250 
systems that may have been shipped with the black plastic CPU module 
guides within the module cage on the hurdle board, could have a  
deformity on the spring face or reached the max. spec. condition 
whereby the module comes into contact with guide causing component 
damage (typically to L1401).

Implementation: 

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

Corrective Action: 

Customers and Field Service Representatives either installing or 
upgrading Enterprise 250 400mhz CPU Modules (X1194A) can avoid 
possible damage to the 400mhz CPUs by following the recommendation 
shown below:

    Each X1194A option includes a pair of new CPU guides, CPU
    module and a Read Me First Doc.  Follow the recommendation
    in the Read Me First Doc. and install to new CPU guides in-
    cluded with the X-Option prior to installing the new 400mhz
    CPU Module(s).
