Replacing the Front Impeller Assembly
The front impeller assembly, which includes the craft interface, is located at the
front of the chassis above the FPC card cage, as shown in Figure 1. The assembly
weighs approximately 14.5 lb (6.6 kg). The assembly is hot-removable and
hot-insertable, as described in Field-Replaceable Units (FRUs) on page 4.
The craft interface is attached to the front of the front impeller assembly. If you are
