A fully configured E120 router consists of 2 switch route processors (SRPs), 3 switch fabric modules (SFMs), 6 line modules, and up to 2 I/O adapters (IOAs) per line module. See Figure 3 and Figure 4.
An IOA shelf (bracket) can be installed on a slot-by-slot basis to create a left and right IOA bay, enabling you to use up to two IOAs in the same slot. This architecture enables you to combine different IOA types in the same slot and to support oversubscribed configurations. Air is pulled in from the right of the router by the fan tray and is exhausted out the left side.
