Quick sanity check before I purchase!

[ Edited ]

Hi all,

 

Just wanted a little advice if you don't mind.  Renovating our place and getting cable run over the next week or so, just deciding what config of equipment to buy.

 

Long story short, I'll have 21 cables run to plates throughout the house, 3 Unifi G3 Cameras, and 2 Unifi AC-Lites (all already purchased).  I also have an Edgerouter X-SFP.

 

My original thought was to just get a 24 port Unifi Switch and hook up the PoE stuff to the X-SFP, but that would mean I would have zero ports left over and I'd need to use a PoE injector for one of the devices.  Not ideal.

 

My thinking is I could either get a 48 port Unifi POE switch, which seems way overkill (but hey you never know right), or a single 24 port Unifi NON PoE switch, and a 16 port Unifi PoE switch.   That way I can run all the PoE stuff off the 16 switch and still have a good 13 or so ports left over for future devices or cable runs should I need it.

 

If I do the latter, I assume I'd just connect both the X-SFP and the 16 port to the 24 port via regular ports.  I could I suppose use the SFP ports, but would that be overkill (plus I'm not familiar with fibre at all and wouldn't really know what to buy in the way of connectors.  I see there are lots of direct attach SFP+ cables but they're not cheap, and I can't really see any direct attach regular SFP cables.  Again though, overkill)?

 

Anyway, what would you do Man Wink

 

Thanks!

 

EDIT:  Would this work? http://www.fs.com/products/40109.html

Not sure if an SFP+ cable is backwards compatible with an SFP port?  I don't believe so but happy to be corrected.

Re: Quick sanity check before I purchase!

I'd get the 24 port non-POE switch for all of your plate cables, and a USW16-150W for the cameras and access points and future expansion needs.  I'd interconnect the two switches using LACP and four of these SFP modules (choose multimode) and two of these for fast linkage between the switches.  

 

One advantage to this configuration is that if you decide a wall plate needs POE, you can just move it's cable from the 24 port switch to the 16 port.  Using fiber cables and SFP ports leaves the RJ45 jacks available for more cables.

 

Also, I'd add in a CloudKey and a USG (USG3 or USG-Pro depending on your expected needs).  The cloudkey will be useful for controlling the Unifi gear in an integrated manner, and the USG is Unifi controlled unlike the ERX-SFP.  Going all Unifi equip will make your life easier in the long run.

Re: Quick sanity check before I purchase!

Ok, for the sake of my sanity, I think I'm going to get the following.  Please let me know if I'm making a horrible mistake:

 

2 x UF-MM-1G (http://ubwh.com.au/product_info.php?products_id=510&osCsid=54139ffc523f233accc008df33a5dc57)

 

2 x http://www.budgetpc.com.au/alogic-0-5m-lc-lc-multi-mode-duplex-lszh-fibre-cable-62-5-125-om1

 

If that's all fine, I just need to work out if I'm better off connecting the router to the 24port switch via SFP and the 16port to the 24port also via SFP or connecting the router to the 24port via regular ethernet and LACP the two switches together.

Re: Quick sanity check before I purchase!

Great, thanks for that Man Happy
I currently run Unifi Controller in a docker container on my NAS but I'm definitely considering a cloud key. As for the USG, I'd prefer to stick with the Edgerouter as I just prefer the extra control, but a complete Unifi system has its charms. I probably won't go that route at the moment though.

So, that gives me the option of either LACP the two switches (not sure I'll need the benefits that provides, but maybe?), or connecting both the Edgerouter and the 16 port to the 24 port via SFP instead. Maybe the latter is the better option to save yet another port, but I should have plenty spare so it's not completely essential...

I had a similar choice, ended up also buying US-24 + 2x US-24-250W switches.

 

The US-24 coupled with one US-24-250W via 2x DAC (https://www.anteny24.co.uk/p/851/moduly-sfp), SPF ports aggregated. US-24 for server(s), US-24-250W for camera and access ports.

 

The other switch (US-24-250W) is for the office, POE ports are for future use (VOIP).

 

At home I had a cloudkey too, but moved the controller to the cloud, so I can manage multiple sites easely. For home only, a cloudkey would be enough and easy to manage.

Re: Quick sanity check before I purchase!

Why use a Cloud Key vs running controller on an existing server?  I also run it on a Docker container on my unRAID server.

So rather than the fibre SFP mentioned above, would it be easier just to use DAC's (also mentioned above Man Very Happy), as I really don't think I actually need a fibre connect.

Would these work? https://www.amazon.com/gp/product/B01LSGGUOY/?th=1&psc=1#LUXAddressSelector_1490187244580

 

 

Just wasn't sure about DAC's as they all seem to be SFP+ and I only have SFP ports.

Re: Quick sanity check before I purchase!

Most SFP+ DAC's won't work in SFP ports.  10GTek does make this: http://www.10gtek.com/search/SFP-to-SFP-Cable-Assembly--0.3-Meter-125.html

 

Which is described as an SFP DAC.  Problem is I can't seem to find it anywhere "normal"...

Thanks Jim,
All my stuff is 1G though (X-SFP, 16-150W, ER-24)

The 24-port and 16-port switches have SFP ports, so the speed gain is unlikely to be material using the transceivers you have suggest4d (1G), over a normal RJ45 10/100/1000 Mb Ethernet port. But I find it convenient to use the SFP ports with either copper or fibre transceivers for uplinking, as it saves PoE capable ports. I've not tried aggregating the SFP sockets, yet, but the RJ45s seem OK aggregated, but some people have had issues.

 

If noise is an issue, I'd avoid the USG-PRO and the USW16-150W. The USW8-150W  switch is silent.

How about non-SFP+ version of that?

Thanks for that!  I did find it at a site that may not be completely sketchy: 

 

http://sale.sfpcables.com/sfp-cable-cab-gsfp-p50cm-30

 

But wow what a horror show of HTML - at lest on my iPad Pro.  I'll have to hit it from a desktop to see if it's any better. For $20 I may just pull the trigger and try anyway.

Ha, I didn't run into that yet.  I also found this site:  http://www.chinasfp.com/category-265-b0-1-4G%20SFP%20Cable.html

 

Same shipping though Man Sad 

 

Free shipping if over $500 though - so there is that (ha!)

Re: Quick sanity check before I purchase!

Yeah, those cables seem quite old, as they only support 4GB FC, and 8 and 16GB FC has been around for a while now.  Honestly, a short SFP DAC cable would be a bit of a "holy grail" for me as its usefulness for "stacking" switches would be ideal

These are close, but too pricey to be practical
