All subsystems are placed in integrated chassis.
The functional host subsystem consists of system backplane, LPU, SPU, and SFU. The
subsystem mainly performs data processing function. In addition, the subsystem monitors and
manages all devices in the system, including power modules and fan modules. The functional
host system can be connected to Network Management System (NMS) through NMS interface.
