performed by the master MSM64i. Packet handling is distributed among the four CPUs
on both MSM64i modules.
Selection of the master MSM64i occurs automatically. The following scenarios describe
the selection process:
• When the BlackDiamond 6800 switch boots with both MSM64i modules already
installed, the MSM64i in Slot A becomes the master.
• When the BlackDiamond 6800 switch boots with a single MSM64i (regardless of the
slot), it is selected as the master. If another MSM64i is added to the switch while
powered on, the added MSM64i becomes the slave. The slave MSM64i can be
inserted and de-inserted in the chassis without disruption of network services.
If you de-insert the master MSM64i while the BlackDiamond 6800 switch is operating,
the slave MSM64i does a soft reset and becomes the master MSM64i.
When you save the switch configuration, it is saved to both MSM64i modules. If you
download a new ExtremeWare image, the image is downloaded to both MSM64i
modules.

The MSM64i has two 144-pin SODIMM sockets, and ships with two 128MB SODRAM
modules installed, as shown in
Figure 1-3 . In the future, the memory capacity with be
increased by replacing the SODIMM module(s).
Only SODIMMs supplied by Extreme Networks are supported in the MSM64i.
