There is a problem in the firmware of the Baseboard Management Controller (BMC) which could cause it to report 'No Input' nonexistent hardware.
S500: There is a updated BMC available in the 184.108.40.206 version of Hardware Diagnostics.
Please follow the upgrade instructions availabe at https://support.symantec.com/en_US/article.TECH246290.html
S400: Currently, a fix is undeway but not available.
S200: The S200 appliances do not have this issue.
This is a cosmetic issue where 'No Input' messages can be generated for nonexistent hardware on the ProxySG.
To determine if you are encountering a real problem, verify first from a Sysinfo whether or not the component exists. If the component is not present and you are seeing 'No Input' message for that component, then you are seeing this BMC issue.
A temporary work-around is to perform a reboot of the ProxySG.
This article will be updated when a approximate timeline is available for the S400 appliances.
