If you have selected logical rack 60, group
0 as your starting address, the largest
1747-ASB module image size you can
create is 24 groups (3 logical racks).
Assigning a larger 1747-ASB module
image size exceeds the maximum logical
rack number.
If you have selected logical rack 5, group 0
as your starting address, the largest
1747-ASB module image size you can
create is 24 groups (3 logical racks).
Assigning a larger 1747-ASB module image
size exceeds the maximum logical rack
number.
