In the E320 router, modules mount vertically in a 15–slot chassis, numbered left
to right (0–16). See Figure 16 on page 31 and Table 3 on page 31 for slot
locations. Because two half-height IOAs can be installed in a slot, the upper bay
is designated Adapter 0 and the lower bay is designated Adapter 1. The router
does not have slot groups.
