 ALL PS/2 Servers with the serverguard adapter, FRU P/N06H8091,                 
 installed may be affected.

 Do not replace the ServerGuard Adapter.  This error                            
 may be caused by either inserting or removing the modem                        
 from the PCMCIA socket, or connecting/disconnecting the                        
 battery-pack to the adapter while system power is on.                          
                                                                                
 TO CORRECT THE PROBLEM:                                                        
   1. Power off the system, then remove the adapter.                            
   2. Make sure the battery-pack is fully charged.                              
   3. Disconnect the battery-pack from the adapter for a few                    
      seconds.                                                                  
   4. Reconnect the battery-pack, and make sure the 3 LED's,                    
      located on top of the PCMCIA modem socket, follow this                    
      sequence:                                                                 
                                                                                
          - CR3 comes on first.                                                 
          - Seconds later, CR2 blinks 5 TIMES in a 5 second                     
            time interval, then stays on for a few seconds                      
            and goes off.                                                       
          - Seconds later, CR3 goes off.                                        
          - CR1 remains off the whole time.                                     
                                                                                
 If problems continue, use normal problem isolation procedures.
