Table 3: Module Slot Locations
In the E120 router, modules mount horizontally in a 9–slot chassis, numbered
bottom to top (0–10). See Figure 17 on page 31 and Table 3 on page 31 for slot
locations. Because two half-height IOAs can be installed in a slot, the right bay
is designated Adapter 0 and the left bay is designated Adapter 1. The router does
not have slot groups.
