Chassis Components

This section lists the main components of a Cisco CRS-1 4-slot line card chassis. It primarily identifies the components that are considered field-replaceable units (FRUs), but where additional detail is useful this section identifies subassemblies that are not field replaceable.

Figure 1-1and Figure 1-2show the Cisco CRS-1 4-slot line card chassis from both the front (PLIM) and rear (SFC) sides.
