Cisco EPA-1X100GE= network switch module

The EPAs are new interface cards that introduce 40 Gigabit Ethernet and 100 Gigabit Ethernet connectivity to the Cisco ASR 1000 Series. Like the fixed Ethernet line cards, the modular interface processor with EPAs offers the same feature parity and functionality as the SPA interface processor and SPA combination. Table 1 shows the features of the three types of interface cards.
