Symptoms

 In a customer environment, there was a failed I2CMUX issue that presented identical to KB:

"How to Detect a Bad (Failed) Front Panel Due to Failed FPP (Front Panel Processor) / I2C MUX (Doc ID 2004628.1)",

wherein no Serial Number is displayed, Base MAC/WWN info shows as all zero, and commands such as "telnet fpp" that are required for F1-15 chassis midplane replacements failed to log in to the Front Panel Processor (FPP). After multiple Front Panel (FP) replacements were DOA, one FP eventually did display Serial and Base MAC/WWN, but the Status LED was still in flashing green state (not solid), and "telnet fpp" still did not allow access to the FPP.

Changes

 Chassis was restarted during a routine XgOS Upgrade, and the issue presented itself at that time.
