rf9000 Posted January 17, 2020 Share Posted January 17, 2020 Guys, I want to do a bunch of motorized blinds that connect to the network via CAT6 POE and all have their own IP address. But we are talking about 20-30 individual blinds, plus all the C4 stuff, etc. How big of a switch can one get with POE ports? I know they have 48 but might need bigger Quote Link to comment Share on other sites More sharing options...
msgreenf Posted January 17, 2020 Share Posted January 17, 2020 You can get more then 1... KWD, sonic30101, mujtaba.khokhar and 2 others 4 1 Quote Link to comment Share on other sites More sharing options...
eggzlot Posted January 17, 2020 Share Posted January 17, 2020 I currently have 3 switches - 1 being PoE and 1 Midspan with 16 injectors you can also get a Midspan so you don’t need all PoE switches Remember a 48 port PoE can’t do 48 PoE devices....

SMHarman Posted January 17, 2020 Share Posted January 17, 2020 You can get 96 port and 144 switches bit realistically you are better off with multiple switches. You would also need to examine the POE budget of the switch and load which may even lead to a bundle of 24 ports with sufficient power. Also you are creating one big point of failure in your automation. Finally heat management and the resulting noise management may be a consideration, have you ever been in a room of large high current POE switches. It's got a lot of hvac going on. So not really a yes answer but maybe helps with some thoughts and considers. Quote Link to comment Share on other sites More sharing options...

There are enterprise grade switches that. But they come with enterprise $$$ cost Quote Link to comment Share on other sites More sharing options...

Just make sure your switch can handle the power budget for all of your PoE devices. Ubiquiti makes Unifi switches that have 24/48 with 500/750W budgets. I doubt you would ever need more than that, even if you used PoE on every interface. Quote Link to comment Share on other sites More sharing options...

Power view shades use Poe for data and power in 1 cable. Quote Link to comment Share on other sites More sharing options...
Cyknight Posted January 18, 2020 Share Posted January 18, 2020 Just get cascading or SPF stacking switches as needed. Unless you're setting up for enterprise, you really don't need enterprise gear and connection, so in almost any scenario, multiple 24port POE switches with SPF ports can be linked together with no noticeable performance loss for these sort of consumer scenarios.

Cart Posted January 18, 2020 Share Posted January 18, 2020 Multiple switches linked together is best. Quote Link to comment Share on other sites More sharing options...

How much would you expect to pay for these? The Unifi 24 port 250W POE switch is C$500. Is that about the price range? Quote Link to comment Share on other sites More sharing options...
msgreenf Posted January 18, 2020 Share Posted January 18, 2020 in my rack right now I have 2 POE Switches (24 port and 8 port) Araknis using SFPs to uplink between them. SFPs on these are 1GB non-blocking so it's a great option to get more ports. If I need more ports I would either replace 8 port with 24port or add another 8 port and use the other SFP port to link them. Quote Link to comment Share on other sites More sharing options...

Is that about the price range? SPF isn't new or pricey as such, a lot of 'medium' price switches have them, ranging from $300 to $800 depending on ports, poe and so on. They wouldn't have to cost more by any significant amount than 'regular' switches Quote Link to comment Share on other sites More sharing options...
eggzlot Posted January 20, 2020 Share Posted January 20, 2020 Speaking of PoE got an email today about this device. Pretty nifty. I use their Midspan https://www.amazon.com/PoE-Texas-GBT-4-IW-Gigabit-Extender/dp/B07Z59SG17/ref=mp_s_a_1_6?keywords=poe+texas+outlet&qid=1579562761&sr=8-6 https://www.poetexas.com/products/gbt-4-iw SMHarman 1 Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 21, 2020 Share Posted January 21, 2020 Nifty indeed, but you got to make sure you have a port with POE++ to feed this pig!! Quote Link to comment Share on other sites More sharing options...
eggzlot Posted January 21, 2020 Share Posted January 21, 2020 8 minutes ago, lippavisual said: Nifty indeed, but you got to make sure you have a port with POE++ to feed this pig!! depends on how much power you need - from the marketing email I received: Here’s the breakdown of the power budgets available based on the type of PoE you have: Traditional IEEE 802.3af PoE (your switch just says PoE) – 10 watts total IEEE 802.3at PoE (your switch says PoE+) – 22 watts total IEEE 802.3bt PoE (your switch says PoE++ or 802.3bt) – 60 watts total Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 21, 2020 Share Posted January 21, 2020 Yeah thats just telling you your power budget at the plate. If you want 4 POE at the plate, you need POE++. But if just 2 ports at the plate, then POE+ will suffice, possibly standard POE depending on the devices of course. eggzlot 1 Quote Link to comment Share on other sites More sharing options...
