We have revised our recommendation in this regard: The relay on the
Gigabit Injectors is actually rated for 60W DC, so it's fine to power an
AF24 via the standard Gigabit injector.
I find it odd that this is an asymmetrical issue. Gigabit uses all four
pairs in both directions simultaneously, so a defect on a pair should
affect both directions virtually identically. This is a lot like a radio
link getting 20db less signal in one direction or the other.
Just curious, has a different *length* of patch cable between the switch
and the injector been tried (could be a reflection issue)?
