Solved Are the 8 POE ports on the ASUS ExpertWiFi EBG19P active or passive?

[YRTFS]

I can't, for the life of me, find any information on the subject. I have no interest in the device if it's ports are passive POE, as the risks are unacceptable to me.

Some of the comments on the Amazon page for this unit state that the PoE is active.

Indeed. Forgot to menstion that I stumbled upon one of those as well, but I wouldn't really trust that, to be honest. I was hoping from confirmation from an actual owner or someone in the know.

Contact Asus and ask them. As that info is not disclosed in the Tech Specs on their website, they would be the best source of information.

It says PoE+ 54V 0.6A on the router itself. It must be 802.3at standard.

This FAQ at least calls it a POE+ router

i assume you must have devices that are not 802.11af or at compliant ?

Netgear offers this nugget - "If your PoE device uses the PoE standard 48V 802.3af or 802.3at, it is considered to use active POE. This means that the device will check the power coming in, and, if it doesn’t meet the device requirements, it just won’t power up."

As RMerlin said, you will have to get on the phone with ASUS to confirm it can supply the proper voltage and current to your devices at their spec requirements.

You may also be able to just use power injectors between the device and the switch port if your device is outside of the 802.11 support range or there is too much voltage drop over the ethernet cable ( length or quality).

PoE is okay, but what doesn't look right with this router is two firmware releases only after initial release in a year time. I wanted to get one EBG15 in Nov/Dec 2024 to see what it is and cancelled the plan after I found it runs on firmware from May 2024.

Do the PoE+ and/or the 802.3af/at standards mandate active PoE?

The only PoE device I'll have is the ASUS EBA63, which will definitely work. My sole concearn is this beeing a passive device and frying some of my other, non-poe stuff.

I'm more concearned with the longevity of the support rather than frequent updates(even if asuswrt 5 is not really production ready yet). My hope is that this will be their gigabit device for quite a while and that they'll launch 2.5 stuff that'll complete the expertwifi range, rather than supplant the EBG19P. I mean, even if they launch somehting more powerful that's still gigabit, I hope they'll still keep the "cheap" option in their line.

EDIT:
Looking at the release notes for the latest 3.0.0.6.102_45537 from 3 weeks ago:

6. Add DHCP IP binding support in SDN.

At least they seem to be going in the right direction with asuswrt 5.

There is no PoE+ passive standard.

 

[YRTFS]

There is no PoE+ passive standard.

So, if a (reputable) manufacturer writes PoE+/PoE++ etc on their device, one can safely assume that said device is active PoE?

 

[Tech9]

PoE+/PoE++ is definitely active PoE, but for exactly the same price you can get better hardware and software devices from a vendor with better reputation in SMB class. The choice is yours, of course. Good luck with ExpertWiFi and share the experience.

If it is only one device and that device says POE, or POE + or POE++ or lists the -af or -at std, just buy a POE + or ++ injector depending on the wattage needed. 20-40 USD likely. If it is an AP, i would get the higher wattage injector than is needed. Weird things happen when APs are underpowered.

Keep using whatever you already have.

 

[Tech9]

@degrub, Asus currently have one single PoE router and one single PoE access point. It will be quite a rough start if they don't work together properly.

Thank you for all the information, gents!
