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
Table 4 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.
