FPC Installation Instructions 3
FPC Description
M20 FPC Description
In an M20 router, up to four FPCs install horizontally into the midplane from the front of the
chassis, below the System and Switch Board (SSB). Each FPC is referenced by the number of
the slot in which it is installed. The slot numbers range from FPC0 through FPC3, from top to
bottom in the chassis. Each FPC accommodates up to four PICs. Figure 1 shows a chassis
with FPCs—each housing four PICs—installed in all four slots.
