HI

i have RB5009UPr+S+OUT with power MTP250-53V47-OD
i have devices support :

24 v : Passive PoE (Pairs 4, 5+; 7, 8 Return) (3 devices)

48v : 48VDC, 0.65A Passive PoE 4-pairs (1, 2+; 3, 6-) (4, 5+; 7, or 2-pairs (4, 5+; 7, 8- ) (1 devices)

its safe i can power both of them without problem’s please guide so i can start

That router can't output multiple voltages. In your case only 48V is available.

Only device that I know that is capable of 24V passive and 48V active poe at the same time is CSS610-8P-2S+IN

Actually, there are a few more devices that can do 24V and 48V at the same time:

CRS112-8P-4S-IN
CRS318-16P-2S+OUT
CRS328-24P-4S+RM
CRS354-48P-4S+2Q+RM

(The RM devices have built-in AC power supplies, the others need two separate external DC voltages.)

You are right, thanks for pointing that out
