The SN Slot is 3 because that is the slot
the scanner occupies in the local SLC
chassis.

image word assigned to the IA16. These
values are determined by converting the
module’s logical rack and logical group
numbers (logical rack 0, G0) to the
corresponding SN words.
The 0–7 and 8–15 boxes are checked
because the module requires more
than one byte of image.
The SN Slot is 3 because that is the
slot the scanner occupies in the local
SLC chassis.
The SN Word is 3 because it is the
SN image word assigned to the
OA16. The value is determined by
converting the module’s logical rack
and logical group numbers (logical
rack 0, G3) to the corresponding SN

requires more than one byte of
image.
The SN Slot is 3 because that is the
slot the scanner occupies in the local
SLC chassis.
The SN Word is 4 because it is the
SN image word assigned to the
OA16. These values are determined
by converting the module’s logical
rack and logical group numbers
