H003814 - SERVER 320 HARD DRIVES LOSE POWER OR HANG                            
                                                                                
                                                                                
 SYMPTOM:                                                                       
 Intermittent drive failures or system hangs may occur on the                   
 PC Server 320 during power-up or during normal operation due                   
 to poor contact on one or more of the seven power connectors.                  
 The female connector is enlarged causing a device to lose power                
 on the 12V line.                                                               
 The loose connection can affect power to any internal device                   
 including backplanes which distribute power to hot-swap drives.                
 On a RAID system, the hard drives would appear as DDD (Defunct).               
                                                                                
 PROBLEM ISOLATION AIDS:                                                        
 - The system is a PC Server 320.                                               
 - A defective contact can be observed visually by examining                    
   the female power connectors. If defective, the cylindrical                   
   metal contact in the plastic connector will be spread open                   
   wider at the top.                                                            
                                                                                
 FIX:                                                                           
 Reform the metal contact(s) in the plastic connector on the                    
 power cable with a small screw driver to reduce the size of the                
 contact.
