Hello,

the question have been raised some years ago (https://www.dell.com/community/Systems-Management-General/What-is-the-CPLD-What-does-it-do/td-p/3590530) but left unanswered. So what a mysterious thing about CPLD (complex programmable logic device) within Dell PowerEdge servers, one can't find on the Dell site? What is the fucntion of CPLD there? Is it necessary to update its firmware (if applicable) while updating firmwares for other internal server devices? As far as I've found out, one should NOT touch the CPLD until it's REALLY needed. So I do not intend to mess with it, especially while don't uderstand the base things about the stuff. Worthwhile answers are appreciated.

Thanks!
