Stack Health
The C360 software provides a Stack Health feature for verifying the integrity of the C360 and
P330 and P330-ML stacking module and cables.
Overview
The Stack Health feature will identify defective modules and cables that may be installed in the
C360 stack. The Stack Health algorithm separately checks all stacking modules and the
Octaplane connections (including Redundant cable).
Implementation of Stack Health in the C360
When activating the Stack Health feature, the agents in all modules start sending special
packets of various length via all stacking cables to one another. The Master module
synchronizes this process and collects the results.
● When the Redundant Cable is present, the user is prompted to disconnect one of the short
Octaplane cables and the redundant connection will be checked. Then, when prompted,
the cable should be reconnected and the test will run a second time to check the regular
Octaplane connections.
● The stack is reset after the Stack Health process completes.
Tip:
Tip:
You should not load the stack with traffic during this test.
Tip:
Tip:
If the stack health process fails, try to fasten or replace the stack cable between
the modules where the failure has occurred. If the problem persists, try to fasten
or replace either or both of the stacking modules.
