Hi,

Finally got my Ethernet cable running outside the house and 10 gb network card in the pc. Now getting 3 gb up and down (my full bandwidth).

I’m going to build a small network rack around the dreammachine se.

My use case is 10 gb connection to the router and a single 10 gb connection to my pc. A nas (2.5 gb fine) and a ubiquity access point.

Am I right in understanding I could do the above with a single dream machine se. From reading, i understand it has a WAN and LAN 10 gig port. could I use them for the connection to the router and pc (giving me the 10 gig). I know I would need to convert the ports to RJ45.

Then the nas and Poe access port would be easy too.

Thanks!

Who?

The 10 GbE SFP ports on on the Ubiquiti UniFi Dream machine SE is designed to be connected to a switch (or WAN) and not a host device. You could connect it to a PC using the correct cable/transceiver.

SFP ports won't negotiate at 2.5 Gbps, only 1 or 10.

You could theoretically use the 2.5 GbE WAN port and change the config for it to be a LAN port, then use one SFP cage for the internet and one to your PC but if you're going to go to the effort of using a rack, just get a suitable switch.
 

Ubiquity - get it from your local market stall. Double as fast, half the price. Pair it with a razor deathcobra and Corsaar headset you’re away!​

​

Key thing is the 10 gig from the router and one to the pc. Rest of devices be fine. Even with adapters sounds like it wouldn’t work.

Previously I was recommended the below which seems sensible. Was just seeing if I could do without the flex. Is this the best setup? I am going to pull the trigger this week.

UDM SE
USW-FLEX-XG
SFP+ to RJ45 adapter to take the 10GbE LAN port on the UDM SE to a port on the USW-FLEX-XG
U6-Pro access point powered and connected direct to the UDM SE

Nothing wrong with their first gen switches however I would personally be getting one of the newer ones. I have the Flex XG in my office and it's fine and I have never heard it.

My issue is I need PoE as well for an AP.

Really interested in what anyone would recommend to acheive the above.

That's not a use case.

Why does your PC need a full 3Gb of internet bandwidth?

No need but why not. Nice to get the full bandwidth.

Currently I'm running a cat6a cable into a 10 gig network card which is working. But want to be able to plug in a AP (it's the centre of the house) and ability to plug in my Nas all in that location.

As your NAS has 2.5Gb, then 2.5Gb to your PC makes sense.


(In fairness with Ubiquiti, Microtik, PFSense etc, they have options to at least fairly share bandwidth so it's less of an issue - but for ISP supplied routers and the like it's far better to not put yourself in a position where 1 device can saturate the whole connection)

The key question is what is your ONT? If the ISP is offering 3Gb speed then it’s not a 2.5GbE ONT so most likely it’s a 10GbE ONT at which point the SFP+ adapter will work (set it to 10GbE in the controller).

The only benefit you’ll get from buying a XG-6-PoE is that it will auto-negotiate on the RJ45 ports to 1/2.5/5/10GbE and do PoE++ (60W) so it’s good, but if you’re buying the UDM Pro SE anyway and the U6-Pro is 1GbE and even the U6-E is only 2.5GbE there’s not a great deal of point. The USW-XG-6-PoE was made specifically to power the UAP-AC-XG range which has the 10GbE RJ45 port and needs PoE++. It’s basically a dead duck device now.

And yes, you probably could do it without the USW-Flex-XG. It just depends how many wired devices you have.

The ONT is 10 gb as far as i understand. It's communityfibre. I'm getting 3.1/3.0 using my 10 gig network card.

Thanks mate, really helpful. Am I correct in understanding with just the dream machine SE, I could go 10 gig in and and 10 gig wired to the PC (without the need for an extra switch). Then use the rest of the ports as per normal?

You would need a 10 Gb SFP NIC in your PC, but yes, you could use the other switch ports. If your PC NIC is RJ45, you'd need a 10 Gb SFP / SFP+ to RJ45 Adapter in the UDM, then connect via Cat5e/Cat6. I won't link as I don't know if OcUK sell them.

This is great. Yeah i know the adapters. It's RJ45.

So really I just need the dreammachine SE, a rack, the AP and I'm good to go.

Sort of. I’m not a big fan of the UDM Pro and I’ve not actually set up an SE since they were launched but I believe you can configure the LAN port as a normal port but it would be a routed port, not a switched port. The other ports on the UDM SE are all switched ports from the internal router.

The problem would come in the future if you wanted to uplink to another switch, you’d need to plug your PC into that switch as you’d need the LAN port to feed that switch. I have no doubt it will work, but it’s not how you’re supposed to implement it. Where were you thinking of plugging in your NAS? For some reason I thought that was the real driver for 2 10GbE ports.

UDM-SE has 1x 2.5GbE RJ45 port, plus 2x SFP+ ports. One SFP+ port could go to his PC, and another to a switch.

The UDM-SE switch ports won't do port aggregation, or any advanced switching features. They're pretty basic and if fully populated will start tanking.

Can you use both the 2.5GbE RJ45 LAN Port and the SFP+ LAN port on the same address range at the same time? I didn’t think you could? It certainly used to be 2 separate WAN ports and 2 separate LAN ports. You can definitely have two hardware LANs but I didn’t think they could both be in the same network although routing between them wouldn’t exactly be difficult.

You can, I can't recall which UniFI OS release it came with, I think it was 3.1.6.

Ports 8-11 can be configured in whichever way you want.

However I forgot OP has 3(!) Gbps WAN.
