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.

Step 1 Access the master spine CLI via Telnet, SSH, or through the SFS 7024 RS232 serial ports. Step 2 The system prompts for a user name. At the prompt enter:

admin

Step 3 The system prompts for a password. At the prompt enter:

adminpass

The system responds with:

Welcome to the SFS 7024 CLI. Type 'list' for the list of commands.

Step 4 To reboot multiple spines on the SFS 7024 enter the following command:

reboot now -m -n

where:

now initiates the reboot process as soon as the user presses Enter (i.e., no system y/n prompt).

-mreboots 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).

-nreboots just the management card of the slave spine (in a non-disruptive manner).

Note If accessing the CLI through Telnet or SSH, the user will need to reconnect to the CLI following the reboot.

Hot Swapping Components

Hot Swapping Spine and Leaf Modules

Note Following are the general guidelines for hot swapping leaf and spine modules:

Caution 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).

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.
