FTOS Configuration Guide for the C-Series - Force10 Networks

SFMs
In a system with nine SFMs, you can designate which SFM is the Standby SFM, and then hot-swap that
SFM with another SFM. At boot time, the system designates, by default, the SFM in slot 8 as the Standby
SFM.
Note: Standby SFM is available only in EtherScale systems.
To change an active SFM to the Standby SFM, use the following command:
Command Syntax Command Mode Usage
redundancy force-failover sfm
number
Use this command only when nine SFMs are present in the system.
Use the show sfm all command in the EXEC privilege mode to view which SFM is currently redundant.
