Hello all,
I’ve acquired this, the manual suggests the PoE facility is auto-sensing, i.e. it won’t send power if not asked for. Is that right? I’m a bit worried about plugging in PC’s,router, etc., even though the instructions show PC’s being plugged in.
Thanks!
i have no clue about that particular switch.
But PoE as in plain “PoE” is usually 24V Passive which will kill hardware that doesn’t expect it.
PoE+ is the 48V sensing that is way more safe, but no clue with that thing.
Documentation says it supports 802.3af, so it should do auto-sense if the connected device requests PoE.
The PoE spec asks for 37 to 57V. The 24V is a “do our own way”-approach taken by some companies.
Ethernet spec requires magnetically coupled ports. That means DC current should not be passing through the device as a result of 24V between some pairs of pins.
well, my crosshair 6 hero didn’t like it. Smoked a bit and Lan didn’t work anymore.
Hopefully it just hit the “languard” thing.
Wow, really sorry to read that.
that’s supposed to be one of the good ones.
Ahhh, well may be I’ll try them with disposable machines as a test. All I know is I very briefly tried plugging them in a machine went funny about it :-/
is the switch managed?
If it is then you can go into it and force turn off POE on a given port
That’s a good point, it is managed so I’ll log in and have a look again. First time I logged in, it didn’t look like I could, but it was an unfamiliar GUI
