The 9-slot LSB card cage is located in the upper left (front and rear) of
the system cabinet, as viewed from the front. The LSB card cage must
contain one IOP module, which is always installed in slot 8. The other
eight slots contain a combination of memory and CPU modules. Unused
slots contain filler modules, which manage the airflow through the cabinet.
The LSB card cage slots are numbered 0 through 3 from right to left in the
front of the cabinet and slots 4 through 8 right to left in the rear of the
cabinet.
