Boy Parnassus, for someone who doesn't work for HPE, you found a site that I had never seen before! Thanks!
That said, the United States and Canada are not even listed!
Hyunuk77, the label on the bottom of the chassis should show all of the certifications that we comply with. Also, if you look in the Installation Manual, I think, the certifications may be there too.
If you need an official UL Certification document, and can't find it on the UL site, I can see what I can find.
Regards,
David
