Knowledge Article: ID B0002205A: Primary MM internal I/O expander failed.

Description

The internal I/O Expander on the primary advanced management module failed during the built-in self-test (BIST).

Causes

The primary management module performs the BIST that checks the internal I/O Expander. If the internal I/O expander test results in an error, the test fails.

Implications

The failure generates this event.

Resolutions

Perform this steps:

If the chassis supports a second advanced management module, and you have a second module installed, initiate a failover to the standby advanced management module. If the standby advanced management module successfully becomes the primary advanced management module, replace the advanced management module that failed BIST at your earliest convenience (for example, during a maintenance cycle).
Replace the advanced management module.
