Msm64I Memory - Extreme Networks Alpine 3804 Hardware Manual

Selection of the master MSM64i occurs automatically. The following scenarios describe the selection
process:
• When the BlackDiamond 6800 series switch boots with one or more MSM64i modules already
installed, and an MSM64i module is installed in slot A, the MSM64i in slot A becomes the master.
• When the BlackDiamond 6800 series switch boots with a single MSM64i (regardless of the slot
position), it is selected as the master. If additional MSM64i modules are added to the switch after
powered on, the added MSM64i modules become the slaves. MSM64i modules that operate as slaves
can be inserted and removed without disrupting network services.
• If you remove the master MSM64i while the BlackDiamond 6800 series switch is operating, the slave
MSM64i experiences a soft reset and then becomes the master MSM64i. For example, if you have a
BlackDiamond 6816 switch with a master MSM64i in slot A and slave MSM64i modules in slots B
through D, and you remove the master MSM64i from slot A, the slave in slot B becomes the master.
Later, if you need to remove the master MSM64i from slot B, the slave in slot C becomes the master.

MSM64i Memory

The MSM64i has two 144-pin SODIMM sockets and ships with two 128 MB SODRAM modules
installed, as shown in Figure 113.
NOTE
The MSM64i supports only SODIMMs supplied by Extreme Networks.

The MSM64i can be populated with any of the memory combinations that are listed in Table 62. If you
are using multiple MSM64i modules, all modules must have identical memory configurations.
