that the pack resides in. For example, in slot 14, the pack uses slots 13 and 14.
Note 2: A DTI/PRI pack cannot be installed in slot 11. The pack would come in
contact with the BTU installed between slots 11 and 12.
Note 3: A DTI/PRI pack could reside in slots 10 and 11, but cannot reside in slots
11 and 12 because of powering restrictions.

packs, provided the balance of equipment in card slots 1 through 8 are already
equipped.
