FT810-O001           

JUN 94

APPLICABILITY:                                                               
This "O" coded FCO should be installed on ALL VAXft 
810 shipped thru March  1994, upgrading all Revision "D" 
and "E" ATM boards to Revision "F".    This FCO 
incorporates the following ECO's: (1) 5421083-BXB02, 
(2) 5421083-TWO003, and (3) 5421083-TWO004.                                

PROBLEM & SYMPTOM:                                                          
Problems existed in version V1.0 of the VMB firmware 
and V1.3 of the CPU   firmware.  These releases of 
firmware correct those known deficiencies.     
 1.)    V1.0 VMB fix for dual session terminal/ELN 
problem                  
 2.)    Zone "B" not correctly blocked from executing a 
boot  command when other zone running operating 
system using V1.3         
 3.)    V1.3 diagnostics may fail if memory installed in 
increments of   64 Meg.  (Failure is Group 2, test 6, 
subtest 1, of RBD's.)       
 4.)    V1.3 did not support examine or deposit commands 
in terminal  duplex mode.                                                        

SOLUTION:                                                                    
Install V1.1 of the VMB firmware if your ATM modules are 
currently rev. "D" to bring them to rev. "E".  Install V1.4 of 
the CPU Flash ROM to bring them to rev. "F".  This new 
firmware corrects the above listed deficiencies.     

QUICK CHECK:                                                                 
Visually inspect the I/O ATM, KD560-AA, for the following 
identifiers on the parts listed below, to help identify the 
"CORRECT NEW" part at locations: 
 E150 -  E150, or 23-037Z4-00, or FBF0

_ DOL, FT810-O002, High ground currents cause system errors

MAY 94

APPLICABILITY: This "O" coded FCO must be installed 
in all DEC 4000-6XX AXP and VAXFT Model 810 
systems that contain a 20A FEU (H7884-AA).
                                                                              
This FCO incorporates ECO No.H7884-TWO003.                   

PROBLEM & SYMPTOM:                                                        
Problem: High ground currents in H7884-AA cause 
random system errors.        
                                                                              
Symptom:                                                                     
 1. DEC4000-6XX systems hang randomly.                                        
 2. DEC4000-6XX systems exhibit power-up random 
(PSC error code 9) failures.  
 3. DEC4000-6XX systems' PSC reports fan speed errors 
randomly.               
 4. VAXft810    systems  (see above)

SOLUTION: Install a new FEU H7884-AA (part revision 
D06).                    
                                                                              
    (Refer to APPLICABILITY section)                                   
                                                                              
QUICK CHECK:                                                                 
 If the system contains a 20A FEU (H7884-AA, part 
revision below "D06")  it needs this FCO.
