The MSM is the internal switch fabric for data that is being sent between I/O modules.
Each MSM has two CPUs for protocol processing, network management, and internal
switch fabric for processing data traffic between I/O modules. Up to two MSMs can be
installed in the BlackDiamond 6800 chassis for full redundancy. Using two MSMs, the
capacity of the BlackDiamond 6800 is doubled, and the system runs faster. Packet
throughput between I/O modules on the BlackDiamond 6800 is 32 Gbps when one
MSM is used, and 64 Gbps when two MSMs are present.
The MSMs must be installed in the center slots of the BlackDiamond 6800 chassis,
labeled Slot A and Slot B. Figure 1-3 shows the MSM.

Management Switch Fabric Module (MSM)
The MSM has the following ports:
• Console port (used to connect a terminal and perform local out-of-band
management)
• Modem port (used to connect a modem for remote access to the CLI)
• PCMCIA slot (for future development)
