Stack Health
The P330 software provides a Stack Helath feature for verifying the integrity of the
P330 stack cascading module and cables.
Overview
The Stack Health feature will identify defective modules and cables that may be
installed in the P330 stack. The Stack Health algorithm separately checks all stacking
modules and the Octaplane connections (including Redundant cable).
Implementation of Stack Health in the P330 Family
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.
Note:
You should not load the stack with traffic during this test.
Note: 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.
