the data sheet for the MA-INJ4  says    "Gigabit compatible"  where in the link you sent does it say  the MA-INJ-4  is 2.5G compatible...

I'm talking that it's compatible with MG51, if you need more information just open a support case.

Hi @CharlieCrackle,

The MA-INJ-4 is an 802.3at Gigabit Ethernet power Injector.  It is compatible with the MG family, but in the case of the MG51 will only provide 10/100/1000Mbps speeds.

If you are looking for 2.5GE connectivity to the MG51, you would require the MA-INJ-6 which is an 802.3bt mGIG power injector.
