Yeah, these SyncInjectors can take up to 56VDC, and it’s an Eltek with a floating ground so we’re able to put out 48vdc. Just to verify that I’m doing +48 if I put my multimeter on, red to red, and back to black I’m reading +53.98VDC which is as expected for +48, right?

I'm assuming you are using a DC-DC converter to convert your -48VDC down to 24V for the SyncInjectors handling the FSK? Also, your rectifier is probably -48VDC, not 48VDC.

This powers 4 Syncinjectors and 2 Netonix. There is a mix of 450 and FSK APs in each of those Syncinjectors. When we powered back up 6 of the 6 FSK wont establish eth link with the Netonix, all the 450 are fine. Ideas? Tower climber en route but I'm stumped. TIA Thanks, `S --- Sent mobile, typed by thumbs.
