SRP Modules and SFMs

The router accommodates up to two SRP modules and three SFMs that act as an
integrated system controller (SC) and switch fabric system. The SC is located on the
SRP modules; the router's switch fabric is distributed between the SRP modules and
SFMs. The switch fabric is divided into fabric slices; each SRP module and SFM has
a resident fabric slice. At least four of the five possible fabric slices must be installed
for the E120 and the E320 routers to operate.
