H123235 - HOT-SWAP TRAY FITS TIGHTLY IN DASD BAY                               
                                                                                
                                                                                
 TEXT:                                                                          
 The hot-swap tray assembly may fit tightly into the hot-swap                   
 shell assembly of some PC Server 320 systems (M/T8640).  In                    
 severe cases, it is possible for an excessively tight fit to                   
 prevent a good connection between the hot-swap tray and                        
 backplane card.                                                                
                                                                                
 When diagnosing hardfile problems on these systems, either                     
 solid or intermittent, examine the fit of the hot-swap tray                    
 in the hot-swap shell assembly.  If the fit is tight enough to                 
 potentially cause a poor drive connection, consider replacing                  
 the tray or shell.                                                             
                                                                                
 If only one hot-swap tray is too tight, and is tight in all                    
 slots, try replacing the tray first, FRU p/n06H3956.                           
                                                                                
 If all trays are too tight, try the hot-swap shell assembly                    
 first, FRU p/n06H5068.
