Chapter 8. DM4000 MPU384
8.1. Overview
The DM4000 MPU384 is a hot-swappable Switch Fabric module capable of handling 384Gbps of non-
blocking data (up to 192 Gigabit Ethernet ports). It is compatible with DM4004 and DM4008 chassis. In
the DM4004 chassis it can handle up to 48 Gigabit Ethernet ports per interface board at a non-blocking
configuration. In the DM4008 it can handle up to 24 Gigabit Ethernet ports per interface board.
The entire 384Gbps data is switched by the active MPU, while the standby MPU monitors the state of the
active MPU. In case of failure, the standby MPU assumes the switching of packets and generates a MPU
failure major alarm to the management system.
The DM4000 MPU384 can handle up to 285,714,285 packets per second supporting 12KB jumbo frames
and has an internal 1.5MB Switching Memory reaching wire speed operation.
The DM4000 MPU384 has a 1GHz microprocessor with 2GB of RAM and 1GB of Flash.
