Important: If you have an optional memory module (1771-DRS1 or
-DRS4) in the second SIMM socket of the coprocessor and the memory in
that socket is configured for battery backup, the memory in the second
socket might become corrupted after power is cycled. This problem does
not occur in the standard factory configuration for the 1771-DMC,
-DMC1, and -DMC4. It only affects memory in the second SIMM socket
on older coprocessor modules with these part numbers:

If you have one of the above part numbers and you want to install and
configure battery backup in the second SIMM socket, return your module
to Allen-Bradley for an update.
