The MSM consists of a printed circuit board mounted on a metal panel that acts as the insertion vehicle
in a BlackDiamond 10808 switch. The module carrier also includes ejector/injector levers and captive
retaining screws at each end of the module front panel.
The MSM has the following ports:
• Console port—Used to connect a terminal and perform local management.
• Management port—Used to connect an Ethernet cable directly from your laptop into the
management port to view and locally manage the switch configurations.
• Modem port—Used to connect a modem for remote access to the CLI.
• Compact flash—Reserved for future use.

MSM Activity

The BlackDiamond 10808 switch can run with a single MSM installed. When you install additional
MSMs, one of the MSMs operates as the master, and the others become the slaves.
The master MSM is responsible for upper-layer protocol processing and system management functions.
For example, OSPF computation and SNMP functions are performed by the master MSM. Packet
handling is distributed among the CPUs of all installed MSMs.
When you save the switch configuration, it is saved to all MSMs. If you download a new ExtremeWare
image, the image is downloaded to all MSM.
