I'm reading that as "yes, you can power it with -48VDC."
Thanks,

Input 48v is transformer isolated, individual on-board voltage
converters have DC negative directly coupled to chassis ground.
AF24 reads 0 ohms from board DC- (also digital ground) to chassis
plate, “no” path between input DC- and chassis plate.
24HD shares the same PCB, so the same applies for that.

Hi,
Is the AF24's internal power supply isolated in such a way that it can
be powered with -48VDC, like other telco equipment with a positive
ground, or will this cause a short when mixed with other -48VDC
equipment on the same ground plane?
Thanks,
