This is where it gets fun: The 10/100 (100 series) and Gigabit Revision H injectors are identical power-switching wise. These are designed to produce a timing pulse with a very quick fall and rise time to mimic the behavior of a CMM3. The 430/320 injector and the Gigabit Revision I injectors are identical power-switching wise. These are designed with a slower rise and fall time to suppress ringing.
The 430/320 injector's reverse protection circuit wants 48V or more (but is ok at lower). The 10/100 and Rev H gigabit injector reverse protection circuit wants 24V but is ok up to around 56V. The Rev I reverse protection circuit works pretty much all across the board voltage wise. The 100 series injector uses spare pair injection on pins 4,5 (negative) and 7,8 (positive). The 320/430 injector uses spare pair injection on 4,7 (negative) and 5,8 (positive). The Gigabit injectors use data+power injection using ethernet magnetics on 4,5 (negative) and 7,8 (positive).
