Hello

I have a RB2011 connected to an ubnt 24vPoE switch.
They are connected together via the port 1 of each switch, and this is where i have a problem.

I want to reset the ubnt switch. It will get factory default, which are PoE+ on all ports. So after reset, the RB2011 will get some 48v in ether1, and i know it does not like it (already did this by mistake on another and the smell was not good).

So, is there an option to PREVENT RoS to get power from PoE/Ether1 ? So i can reset my ubnt without problem.

Thanks

Can you use 4wires cable instead of 8wires?

Unplug the cable ? Plug it again after you set up the switch.
If that is not an option and there was such a setting you would leave the device with no power at all and that defeats the purpose.

Sure Cybertod, but
1) the RB2011 is already powered by its own power supply, i don't need that Poe anyway
2) the whole purpose is to avoid sending someone for a 6 hours drive, just to handle a cable :p

The 4-wire cable may be a good option for the future.. or just always use RB2011/eth2 instead of eth1

So, is there an option to PREVENT RoS to get power from PoE/Ether1 ?

No options like this in ROS. You can configure only PoE-OUT options.

PoE+ on the UBNT switch should be 802.3af compliant. It should not be 48v passive.

Probably you are right, but yesterday I've experienced a problem on a brand new rb2011 ether1 connected to cisco-poe-switch(AF/at). Rb2011 had his power ..after some minutes switched off. It come out was the poe in on ether1 causing switch off
