• 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.
Step 1 Remove the module by pushing up on the handles to disengage from the lock notch. Once the handles
are disengaged, gently pull the handles out and slide the module out of the slot.
Step 2 To install a module, hold it so that the ejector handles are on the bottom.
Step 3 Pull the handles out to extend them. Slide the module into the appropriate slot of the chassis until it

Step 4 Push the handles in to fully close.
