Emerson MVME55006E Manuel D’Utilisation

Row B of the P2 connector provides power to the MVME5500 and to the upper eight VMEbus 
address lines, and additional 16 VMEbus data lines. Please read the configuration notes below 
as they apply to the P2 connector. 

1.

When J28 is configured for IPMC mode, –12V is supplied to P2 pin A30. If there is an 
incompatible board plugged into this P2 slot, damage may occur. 

2.

When J32 is configured for IPMC mode, +12V is supplied to P2 pin C7. If there is an 
incompatible board plugged into this P2 slot, damage may occur.
