Just installed an RB4011 in a client site. They had an existing Yealink W60B phone there, powered by a plug-pack. The specs on the plug pack say 600mA output. Tried plugging the phone in to the poE port (10) on the RB4011, with no success. The W60B showed no evidence of seeing power. Tried setting poe-out on the port to "forced-on", no change. The Yealink doco says it requires "IEEE 802.3af, Class 1" PoE. I can't find any such spec for the RB4011, just lots of statements that it is passive PoE. Is there a trick or should I give up?

I don’t think it’ll do what you’re expecting. Mikrotik POE is just passive POE (i.e. dc constantly supplied over ethernet. It’ll be at whatever voltage your mikrotik plug pack is (usually they’re 24v). 803.2af is up to 15w at 44vdc, and requires a handshake (see https://www.ieee.li/pdf/viewgraphs/introduction_to_poe_802.3af_802.3at.pdf for details) You’re probably going to need to either keep using the plugpack, or put a POE injector in the line to the phone Regards, DG On Thu, 18 Nov 2021 at 8:56 pm, Karl Auer <kauer@nullarbor.com.au> wrote:

I don't do much with VoIP but I installed a Polycom phone recently. It takes 24V on the DC plug and works fine with a Mikrotik plug pack, but ohhh noooo, it can't work with 24V PoE in, it has to be 48V or 802.11at/af. Thank goodness I had a CRS328 with PoE on site.

I wouldn't necessarily categorise passive PoE-out as 'useless' :-D When powered by 24v PSU, then sure - there is certainly some limitations on use of the PoE-out feature: as in it can only be used to power other devices that support 24v PoE Input. But throw away the 24v PSU and poer up your MT using 48v (for those devices that support >=48v supply) then you can power almost anything with that PoE-out port! Remember - 802.3af/at (etc) is all about the 'power-ing' device and not the 'power-ed' device - those active PoE mechanisms are intended to allow the power-ing device to manage power budget for connected devices and avoid being cooked by too many devices draining more current that the supply can manage. I've not yet come across a device intended to be powered by 802.3af/at that doesn't work when powered by passive 48v PoE - not saying they don't exist, just that I've not encountered one yet ; ) - so long as you have the right wiring scheme (i.e. 'type-A', 'type-B') then passive PoE should work fine for most.

I tend to agree with Mike. Not only is it useful sometimes with 48v power but it's very useful in powering other Mikrotik devices. Especially in building and microwave environments. If it were useless they would sell no powerboxes. Sure it's not a POE switch but that does not make it useless. Matt On 22/11/21 11:47 am, Mike Everest wrote:
