Rebooting Multiple Managed Spines
In a redundant management configuration it may occasionally be necessary for the user to reboot both
managed spines in a hemisphere. This is accomplished through the CLI of the master spine.
Access the master spine CLI via Telnet, SSH, or through the SFS 7024 RS232 serial ports.

Hot Swapping Components
Hot Swapping Spine and Leaf Modules
Note
Following are the general guidelines for hot swapping leaf and spine modules:
Be certain that the managed spine to be hot swapped is a that same firmware level as all other

components in the SFS 7024. A hot swap of a managed spine with another firmware level will cause a
disruptive reboot (i.e., I/O traffic is interrupted).

Welcome to the SFS 7024 CLI. Type 'list' for the list of commands.
reboot now -m -n
now initiates the reboot process as soon as the user presses Enter (i.e., no system y/n prompt).
-m reboots just the management card of the master spine. This is a non-disruptive reboot (i.e., the
reboot will not interfere with any switch traffic).
-n reboots just the management card of the slave spine (in a non-disruptive manner).
Hot swap one module at a time, allowing the chassis to completely update it before hot-swapping
the next module. The module update is complete when it becomes visible within the Chassis Viewer
GUI. Listed below are the approximate times to fully update each module type:
–
Spines modules: up to 4 minutes
–
Leaf modules: up to 2 minutes
When a management spine is hot swapped, the rest of the chassis will continue to move packets
without interruption.
There is no need to reboot the chassis when replacing either a spine or leaf module.
