2.7.3.1 Extracting a Spine Module
Extracting Spine Module #1 or #2

management module #2.

If you need to hot swap spine #1 or spine #2:
Step 1.
Make sure that two management modules are connected to the switch system. See
Figure 50 .
When a slave management module is not installed or not working, hot-swapping the
spine module connected to the master management module will cause the chassis to
crash.
Neither the CLI nor the GUI management tools will allow you to shut down spine #1
or spine #2, as the management modules are connected to the chassis components
through these spines.
Removing spine #1 causes management module #1 to reset.
Removing spine #2 causes management module #2 to reset.
Warning : If the spine you want to hot swap is connected to the master management
module the management module will reboot when you take out the spine.
Do not extract spine 1 or 2 if only one management module is connected! Doing so
will cause the switch system to hang which will lead to traffic loss.
