BlackDiamond 12800 Series MSMs
The BlackDiamond 12800 series MSMs are the MSM-5 module, MSM-5R module, and MSM-6R module. 
These MSMs provide the active switching fabric and CPU control subsystem for the switch. The 
BlackDiamond 12802 chassis has one dedicated MSM slot; the BlackDiamond 12804 chassis has two 
dedicated MSM slots. One MSM is required for switch operation; however, adding a second MSM to a 
BlackDiamond 12804 chassis increases system availability through redundancy. Each MSM provides 
192 Gbps of switching throughput through three ASICs. Each module also contains a temperature 
sensor, nonvolatile random-access memory (NVRAM), and a real-time clock.
The MSM-5 and the MSM-5R and MSM-6R modules support different sizes of Ternary Content 
Addressable Memory (TCAM). The MSM-5R and MSM-6R modules have more memory available for 
routing tables, learned MAC addresses, and access control lists (ACLs). For specific details about 
memory allocation, refer to the data sheet for each module. 
CAUTION
You must use compatible MSMs and I/O modules from a single BlackDiamond 12800 module series. Do not attempt 
to mix MSMs from the two different series. The ExtremeXOS software recognizes the MSM type installed in your 
BlackDiamond 12800 series switch and only allows use of a second MSM of the same type and compatible I/O 
modules from the same series. An error message is displayed if you attempt to mix module series.
Software Requirements
 lists the minimum software revision required for MSMs in the BlackDiamond 12800 series 
switches.
Make sure your BlackDiamond switches are running the required software version to support the 
switch model and MSM type. The MSM-6R requires ExtremeXOS 12.0.2 or later. A BlackDiamond 12802 
switch running software earlier than version 12.0.1 will not be fully operational.
To upgrade the software in your BlackDiamond 12802 switch, access the latest image at the Extreme 
Networks support website at 
http://www.extremenetworks.com/services/services-hub.aspx
. Follow the upgrade 
instructions in the ExtremeXOS Release Notes.
NOTE
The MSM slot in the BlackDiamond 12802 switch is labeled MSM on the front panel. The ExtremeXOS software 
refers to this MSM as MSM-A in all related displays and command output.
