Have a SAF POE injector. The 48 volt input voltage is good. Have a dim blinking green light that does not change even when you unplug cat-5 going up to main unit. Its been running for 6 months and I have just not got this tower totally switched over too it yet and few days ago I received an alarm on it. Is this a sign the injector is bad? I have a spare POE injector just have not gotten back out there with it yet.
