SG2005P-PD where to enable POE injector mode?
Okay, I'm stumped. I can usually fumble through the settings to find what I need, but can't seem to find where/how to make the new 5 port switch utilize injector mode (I am used to the Unifi Flex settings) so that I can use the full POE power through this switch. I am using an Airfiber 50v 60w injector as I have a lot of these that I use for the Unifi Flex switches. Right now the SG2005P-PD is only allowing very minimal POE power like it is not detecting that I am using a POE++ injector. How do I force it recognize the POE injector?
Issue resolved, now I see full power budget, thanks to @Clive_A and dev team.
I'm just hope that auto detecting of poe injector type changing will be added in the next firmware (or at least correspondent notice will be added to wiki/manual in bold text %)
From dev team :
If you used POE/POE+ injector before when Controller adopted the device, this kind of problem may occur when you change to POE++ injector (e.g. POE170S), usually you just need to click Force Provision in the device configuration to solve this problem.
It powers on with the injector. The switch will only power one POE device as it "thinks" the POE budget is maxed out.
I also noticed that it doesn't matter whether or not I plug in a POE++ injector or powering from an Omada POE switch, I still get the same 4.00W POE warning. How does the SG2005P switch know how/when to allow the proper POE budget? Is there a setting in Omada that toggles POE injector mode or is it supposed to be automatic? With Ubiquiti Unifi equipment, there is a spot to "toggle" POE injector mode in the controller settings.
Hi @RSCW
Thanks for posting in our business forum.
What's the Omada switch you tried?
Based on the email conversation with the dev and test team, we tested SG3206HPP with SG2005P-PD, and the 2005P-PD can successfully sync to 802.3 bt and give power to other devices.
So, we assume it is still a problem with the cable leading to a bad sync in PoE.
Need the following information:
1. Use show power inline to collect the real power budget. CLI.
2. Swap with a different cable.
3. No matter what kind of adapter you tried, even with the Omada switch which supports PoE+, it always shows the PoE Max light?
4. Controller version. The model number of the PSE you have tried.
Hi @RSCW
Here's the followup.
So our dev thinks that might be an issue with the UNBT injectors. Our SG2005P-PD only supports standard PoE while the the injectors you used seems to be not standard IEEE 802.11bt. To prevent damage to the SG2005P-PD, it does not allow the power.
The dev team said they'll purchase two of these for further analysis.
If you don't want to wait for the results and miss your return window, you might decide to return. Till we get a final result of this, you can keep your money at least.
Update in Jan 24th:
In addition, the reason why it shows you have 6-7W left in the budget is because the non-standard PoE works in a similar way as the IEEE 802.3af, so it only provides around 15W max. After deducting the power consumption of the switch(SG2005P-PD), it left with that amount of power. So that's why is shows up like that and you cannot have other devices connected to draw power from it.
So, if you need to use this model, please make sure your PoE injector is giving standard IEEE 802.3bt which can work with our switch correctly.
Thanks for your understanding.
