configurations. This port can also be used to connect the system to a parallel management network
for administration.
● Compact flash—You can insert an external compact flash memory card into this slot. (See Chapter 2
for more information about Extreme Networks-supported compact flash cards.)
● Reset button—Use the Reset button to reset the MSM without removing the module from the
chassis.
NOTE
Although the BlackDiamond 12800 series MSMs are similar in appearance, each MSM model has specific features.
The MSM-5R and MSM-6R modules belong to the R series and include the rate limiting feature, which the MSM-5
module does not support.
To use rate limiting, you must install modules with model numbers ending in R. These include the MSM-5R module
or MSM-6R module and the GM-20XTR I/O module, the XM-2XR I/O module, and the XM-2HR module.
The MSM-6R module provides the same functionality as the MSM-5R module, with higher performance
for CPU-based activities such as BGP, OSPF, and MPLS.
BlackDiamond 12800 Series I/O Modules
No configuration information is stored on the I/O modules; all configuration information is stored on
the MSMs.
When a BlackDiamond 12800 series switch is powered on, the software generates a default
configuration for any slots that contain I/O modules. The default configuration allows the I/O module
ports to participate in the VLAN named default. The default configuration for the I/O module is not
preserved unless you explicitly save the configuration to NVRAM.
You can configure parameters of an I/O module after it is installed, or preconfigure a slot for a certain
type of module and configuration. The preconfigured information is applied to the module after it is
inserted. If you preconfigure a slot for a specific module type and then insert a different type of
module, the module reverts to its default configuration.
NOTE
See the ExtremeXOS 12.0 Concepts Guide and the ExtremeXOS 12.0 Command Reference Guide for more
information about configuring the modules.
