1) The R650's maximum throughput is quite a bit higher than 1Gbps, but there are very few current client devices which will connect at >1200Mbps & it's unusual to have several devices pushing 1Gb of traffic simultaneously at home, so gigabit is unlikely to cramp your style much.
2) If the passive injector is 802.3at or 802.3af compatible, but is just missing the handshake, then you might be ok if it can provide 21.59W (or at least close to this). If the injector is just firing 12V/24V down the wire then the AP either won't work or could be damaged.
3) If you jump onto AliExpress you'll find 802.3at injectors which can be powered off 24V DC, e.g.

Your R650's spec is 21.59W though, so I'd want the 24V DC supply to be at least 1A.
Yep, I understand how DC works. I built a custom DC->DC UPS using one of those Mini-BOX DC-DC Open UPS boards, an ammmo box, and a 12v 10AH battery, and the uptime is insane compared to commercially available UPS:es! (~11.5 hours from a single 12v 10AH battery)
It should be able to supply about 9amps if push comes to shove (though I will need to upgrade the power brick to support that). 1 amp should be no problem. Right now I can handle up to 6 amps, and the other device pulling power on it maxes out at 0.8a at 24v, so I have plenty of leeway.
I did a little writeup on this UPS build
here if curious.
Incidentally, PoE switches have come down in price a bunch. Have a look at the 2.5Gb switch guide - it might be good to upgrade this at the same time. I pulled out my 1Gb managed switch and collection of DC UPSs and put in a
4x2.5Gb+2x10Gb PoE managed switch on an ordinary online UPS for $200 total cost.
Wow. Those switches are quite amazing at that price. I have some pretty serious trust issues about letting anything designed in China and sold on AliExpress anywhere near my network though.
Right now each of the two locations where the AP's need to go have a
Mikrotik CSS326-14G-2S+RM. One of the SFP+ ports on each is a 10gig fiber uplink. I figured if I need 2.5gig to the R650's, I could use one of the 10/5/2.5 copper SFP+ adapters I have kicking around, but I'd need to find a compatible DC->DC PoE injector for that.
In my googling I can find:
- 802.11af and 802.11at injectors listed as 2.5Gbit, but with direct AC inputs.
- 802.11af and 802.11at injectors listed as Gigabit, but with the DC inputs I am looking for.
I just cant seem to find both DC input AND 2.5gbit...
Also, from what I am reading, injectors reading "gigabit" might just work with multibit, as they arent exactly active in the data path. As long as the signal is sufficient, older gigabit injectors
might just work at 2.5gbit... It just won't be "supported". Such is the deal - I understand - wuthg the Ubiquti PoE+ injector. Officially Gigabit, but works at 2.5gig. At least
according to this thread on Reddit.
I could always start with gigabit, maybe it will connect at 2.5, maybe not. if not I can keep looking and decide if 2.5gb is worth it later. To your point there isn't going to be much (or anything in my house) that is going to tax them above the gigabit level.
Most they are going to see is a couple of old laptops with Intel 7260-AC WLAN cards, one newer laptop with some sort of ax capability, a couple of recent Pixel phones with ax, one recent iPhone with ax (I think) an older iPad (probably ac) and a couple of b/g/n "smart" thermostats (which will be isolated on their own VLAN)
I have 10gig SFP+ fiber throughout the house (and a couple of limited 40gig QSFP+ runs) but nothing wireless is likely to do a lot of internal traffic. Most of the devices on wireless are likely going to be predominantly accessing the WAN, and that is limited to gigabit anyway...
So your point is taken. I may not need anyhting beyond gigabit on the Ruckus devices.
I'm a little bit allergic to upstream blocking configurations though. (at least except for the wan interface
)
