What version of RouterOS [software], BIOS [firmware], and PoE [firmware] use in both board?
What Voltage and Ampere you use for power the Routerboard?
But one moment.... RB951G-2HnD do not have PoE out feature........ only RB951Ui-2HnD
The max power consumption of RBSXT5nDr2 are 8W,
if you power the system @ 12V, use 0,666A.
Maximum Amper on RB951Ui-2HnD PoE-out port are 0,5A
On load the RB951Ui-2HnD stop powering the PoE out for overcharge.
For made work both devices, you must power RB951Ui-2HnD (max 7W) with power source 18V 1,5A [my suggestion] or 24V 1A
