High Availability To establish a redundant switch management configuration, you must have two
Operation Switch Fabric Management Modules (SFMMs) installed in the chassis. The slots for
management modules are M1 and M2.
A redundant SFMM configuration provides a seamless flow of management
operation. After the failover mechanism reboots the system, there is no loss of
configuration data.
