Lumin X1 Fiber Optic Network Discussions

Hi Joe - welcome! Your X1 should be arriving any day now! Exciting stuff.

I’ll defer to Peter on the latest and greatest parts for the Fiber connection.

Talk to you soon.

What is the current thinking about how to accomplish what I want to do?

The standard fiber configuration of Lumin X1 is like this:

SFP switch + SFP module - (fiber) - SFP module + Lumin X1

The WiFi router, NAS, or Roon Core should be connected to the SFP switch via Ethernet.

For sample configuration:

SFP switch such as:
https://www.amazon.com/SYSTEMS-24-Port-Gigabit-Switch-SG11224NA/dp/B00VPT8XSQ
(1. The Amazon photo is wrong, the switch should be compact. 2. This is an end-of-life product that Cisco ceases hardware support on December 31, 2020. 3. It used to be available as a new unit for less than $99.)

A pair of the same brand and type of single-mode 1310nm SFP modules such as:
https://www.amazon.com/dp/B00U8PN0NQ/ref=psdc_537316_t1_B0000AZJZL
(This choice of SFP module needs to be compatible with the SFP switch above. Note that SFP+ is not supported.)

LC-LC single-mode 9/125um Corning duplex fiber:
https://www.ebay.com/itm/3m-LC-LC-D...h=item4d72f2c9be:g:mdUAAOSw7tVa7Ocm:rk:3:pf:0

In this setup, it is absolutely important not to connect both the fiber and copper Ethernet to the switch - this creates a loop and will bring down your whole network. We actually had someone try this in our office by mistake, so I can tell you the effect. :lol:

I have the option of installing another network card in the QNAP NAS that has one or two SFP+ ports and possibly going directly to the X1 via the appropriate SFP+ modules and fiber. That seems to be the most direct but I am not sure how exactly the QNAP's new SFP+ ports would get their I.P. addresses

A Taiwan review of Lumin X1 actually did something similar, and I translated the article here:
https://www.audioshark.org/showthread.php?t=15466&page=4&p=263007&viewfull=1#post263007

A fiber bridged setup should look like this (but we never tried this at Lumin, so at this time I don't recommend people doing this unless they really want to try this):

WiFi router or switch - (CAT-5e / 6) - copper Ethernet port of Lumin X1 - SFP module + Lumin X1 - (fiber) - SFP Module + QNAP SFP network card

In this setup, both copper and SFP network ports of Lumin X1 are used, but no loop is formed here. The Lumin X1 bridges the QNAP to the network, so the QNAP gets the IP address from the WiFi router. Everything is still on the same subnet. You should not need a FMC here.
 
Thank you Mr. Lie. I have decided to try both configurations with the QNAP expansion card and with a switch similar to the one that you mentioned in your post above.

Just to be clear, the QNAP is no longer connected to the switch via copper of any sort and only via the fiber is this correct or can/should it be? The reason I ask is that the NAS also serves additional duties on the network and is not simply dedicated to music server duties.

Thanks again!

Joe

I will be very interested in the answer - as I am in exactly the same boat - my NAS also has dual duties - as a music server & back storage - hard drive allocation is also dedicated - that is drive 1 solely for music mirrored-backed up to drive 2 - drive 3 computer backup mirrored-backed up to drive 4 - NAS is a Synology Diskstation DS418.
 
We think alike. My concern was in asking the X1 to handle all sorts of other data it wasn't designed to do. If I prefer the NAS connected directly to the X1 via fiber and the QNAP can't handle both copper and fiber at the same time I may need to think about adding an additional NAS.
 
My understanding of Peter's Post is the "switch gets its nickers in a knot" when presented with both copper & fibre - no idea what the NAS will or will not do.

1. Standard setup: If you have not purchased the QNAP SFP network card yet, then just connect the QNAP to the SFP switch using copper Ethernet. Lumin X1 is connected to the SFP switch using a fiber and a pair of SFP modules.

2. If you have already purchased the QNAP SFP network card, then there are two possibilities:

A. Fiber NAS setup: Connect the QNAP SFP to the SFP switch using fiber and a pair of SFP modules. Leave the other QNAP Ethernet port(s) disconnected. Lumin X1 is also connected to the SFP switch using another fiber and another pair of SFP modules. (If your SFP switch is a managed switch, you may be able to use QNAP port trunking feature, but I cannot help you there.)

B. Fiber bridged NAS setup: Connect the QNAP SFP to the Lumin X1 using fiber and a pair of SFP modules. Leave the other QNAP Ethernet port(s) disconnected. Lumin X1 copper Ethernet is connected to a network switch or WiFi router. In this setup the switch does not need to have SFP port at all.

In 2B if you power down the Lumin X1 (bridging the QNAP to your network), your QNAP will be offline from the network for other uses. Please note that neither 2A nor 2B are tested by Lumin.

I guess the QNAP can handle both at the same time - the problem is making a sensible network setup that works for you. If you really want to use both (which I don't recommend if you're creating a network loop), you may need to enable Spanning Tree Protocol.

Thank you wklie!

I snagged a used QNAP card from an auction site at a price I was unable to refuse. The switch I intend to use is managed (TP-LINK Jetstream T2500G-10TS). I will be able to try all combinations of 1 and 2.a and 2.b before all is said and done.

My end goal if at all possible is to eliminate any copper Ethernet into the X1. Step 1 above would accomplish this will little muss or fuss but the experimenter in me wants to play with the options in Step 2.
 
Hi
Anyone tested 8-port switch with 2 SFP?

My X1 is on the way and I am planning to set up fiber connection though I am a complete noob at networking.
Anyway, my current howe router set up as follow:
1. Primary router is about 35-feet away from my AV system.
2. Ethernet cables laid from 3 router ports to 3 x 8-gigabit port switches at my AV system
3. I have a 4-bay Synology NAS connected to another router port and tucked away in the same place as the router.
- The NAS is used primarily for my data backup and movie library for streaming

I plan to get a dedicated QNAP 2-bay NAS for my music library (about 7TB) to be connected to the X1 via fiber.
The NAS will be at my AV system next to the X1.

Questions:
1. Based on my existing and planned QNAP setup, what is the best way to setup my X1 fiber connection?
2. Can I connect 1 of the free ports on my existing switches to a FMC and then to the X1 and for the new NAS to be connected to another port on the existing switches? Dont think it will work though.

help and advice much appreciated. Thank you.
 
Yes, you can do that (if I understand you correctly).

Which 2bay qnap nas shod I get for the x1?
its going to b a dedicated Mas for streaming my music library to the x1
 
Regarding a 2bay NAS, I personally would want to be able to set up a RAID5 or something for some level of protection should one of the disks fail so I'd recommend a 4-bay NAS if your budget could handle it but that's just me. How do you intend to integrate the NAS into your system? Via Ethernet, via wireless, or (and I don't even know if this is possible) connected directly to the X1 via USB or something?

As far as my network is concerned, I ended up replacing two old Netgear un-managed 1GbE switches with a QNAP 12-port 10GbE switch with a bunch of SFP slots running 10GbE fiber from the QNAP TS-879 to the switch and 1GbE fiber from the switch to the X1. Nothing else in my system is currently 10GbE but when I get the itch I can start that migration as needed/desired.

1. If your switches do not support SFP, I suggest replacing one switch with a SFP switch, so that X1 can connect to it via fiber and a pair of SFP modules. The new QNAP should also connect to this SFP switch via copper Ethernet. Please see post #108 for alternatives.

2. Yes, that should work. The FMC and the SFP module to be inserted into the X1 has to be compatible though, e.g. TP-Link MC210CS with TL-SM311LS. However, I think using a SFP switch is superior to FMC.

If you like to buy a 2-bay QNAP, take a look at the fanless HS-453DX . Fanless stuff is especially good for audio purpose.
 
Thanks for your advice and inouts
I ordered the TP-Link switch as recommended by blue-sky but I bought the 24-port instead

https://www.amazon.com/gp/product/B01N815NEO/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

As for the SFP modules, I ordered a pair from Amazon from the link provided by Peter

As for the fiber cable, the ebay seller doesn't ship international.
I believe I need a pair? Nas SFP port to switch n switch to X1?
Anyone can link me a seller that does international shipping of the fiber cable?

As for the NAS, I was looking at TS231B n the pci-e SFP card but I m also looking at the one that Peter recommended

Thank you again
 
@bluesky
No wireless connection for my system
@peter
The HS-453DX uses rj45 so its not a SFP port n if I were to get this nas then it has to be copper connection from the nas to the SFP switch.
I prefer end to end SFP connection

But fanless is good though

For the connection between the Lumin X1 + SFP module to the SFP switch + SFP module, you need one duplex fiber cable, try this: https://www.fs.com/products/68296.html

It takes 2 weeks to ship though. If you determine to use fiber connection between QNAP and the SFP switch, then you need the QNAP fiber network adapter, an extra pair of SFP modules, and an extra duplex fiber.
