Hello,
The cp016475.exe is an executable Smart Component. If you launch the executable, fill in the needed IP information and a user name & password, the executable will install the firmware for you.
Be sure to follow HPE Best Practices and have a complete backup of your data along with a period of no or low host IO.
Cheers,
Shawn
