Proliant 380 G6 replace 3.5 -> 2.5 HDD

Good afternoon.

There is an HP Proliant 380 G6, s/n: CZ201020JK.
It was established 6x3.5 HDD. I want to put the cart 8x2.5 HDD (496074-001 ). What to do this, and if at all possible? Where can I find the manual?
I looked at the server, there is (576323-001)
