You can install two NPUs on the chassis of the CX600-X2-M16. The two NPUs can work in 1
+1 or 1:1 mode. In 1+1 mode, the NPU-120-E is connected to the eight PICs. In 1:1 mode, the
NPU-120-E is connected to the sixteen PICs.
The NPU-120-E consists of the following planes:
l Control and management plane
Through the management channels between MPUs and NPUs, the MPUs can manage
NPUs and associated subcards, and transmit routing protocol data.
l Data forwarding plane
The NPUs are responsible for service processing in the entire system, and are connected
to all subcards through data channels.
