T710 running off of cable plant power

unknown

We are looking to install a Unleashed T710 in a area of our system where cell service is poor for our service techs to connect back to the office. We have 1 remaining HFC power supply with a 90 V power injector to a piece of .500 coax. Is there a way to convert that over to something that the T710 can use while being strand mounted? We have converted to GPON in this area so the T811-CM is not an option for us.
