Lumin X1 Fiber Optic Network Discussions

BlueSky said:
In the Network and virtual switch page in the NAS you should be able to see that information. I may have been wrong above and you may still need to connect the switch to the NAS via the fiber cable before the router can assign the IP via DHCP.

Regarding the IP for the SFP, it can and probably should be set manually. I did that for mine so I could remember what the IP of the NAS was when I transitioned fully to fiber.

Btw, are u using static IP for your NAS?
 
Yes I use static for both my NAS systems so I don't have to rely on QFinder all the time. Also, when I map network shares it's easier.

What is the model number of your switch?
 
Certainly should do the trick and it certainly does because you've proved that the RJ-45 connections work properly.

With my setup including an un-managed QNAP 10Gbe switch https://www.amazon.com/gp/product/B07CDJ9YGM/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 , I used https://www.amazon.com/gp/product/B00U8Q7946/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 for the switch to NAS connection (using multimode cables) and https://www.amazon.com/gp/product/B00U8Q7946/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 for the switch to Lumin connection with single mode cables.

I'd focus on getting the router to switch to NAS fiber link working first swapping cables and the SFPs around in case one of them is bad for whatever reason.

Powered off and on the X1 and still had Network Error
The Lumin app could not detect the X1 too

The most common reason for X1 fiber network error is that the SFP module is not inserted fully. Also power on the X1 only after the fiber has already been connected at both ends. You should be able to check the LED at the switch.

A managed switch is not the best idea for most audiophiles except those who consider themselves to be network experts. It's not clear to me whether the switch needs to be configured to enable the use of SFP ports.

Another risk is the use of TP-Link switch with a Cisco SFP module. I know that Cisco switches do not work with non-Cisco SFP modules by default, but I don't know whether TP-Link switches can work with non-TP-Link SFP modules (I hope they do). That's why our recommended configuration is a Cisco switch with Cisco SFP modules. When we used TP-Link FMC (post #3) we also used TP-Link SFP module to ensure compatibility.
 
Yup I was too quick to the draw and went ahead to get the TP-Link managed switch
Anyway I finally went ahead with the Cisco 24port switch due May 6.
 
For the TP-Link managed switch, please go into its management setting and check that the SFP ports are included in the default VLAN instead of being isolated. Although I don't think this applies to your model, you may also check whether the SFP ports are shared with other RJ45 port as combo ports - in that case a few specific RJ45 ports must not be used if the SFP slots are needed.

The RJ45 ports on TPLink admin page is not shared with the SFP ports.
Nothing is on the default VLAN page

Check with TPlink support and they told me that since my Qnap TS332X is SFP+ 10GbE, I need to change the speed of the Qnap NAS to 1000Mbps and re-negotiate. Not sure how to do this though.

fs.com reverted and they confirmed their SFP module will not work with the QNAP TS332X since its a SFP+ port:

"Yes, the 1G SFP can not work on the 10G SFP+ device, so your connection described above is not accessible.
If you want, we can also provide the 10G SFP+ optics, I am now checking the optics compatible for you, please wait for a moment."

I think the X1 is only a SFP port and not SFP+
I thought the QNAP TS332X SFP+ port was able to auto detect and switch speed to 1000Mbps
Damn......

On the switch end, the fiber ports with the SFP modules inserted (for the NAS and X1) were lighted up and status was "Link is Up".
On the NAS end, it showed SFP+ adapter as "Connected" with an IP address.
On the X1, it was still "Network Error".

My Cisco switch will arrive tomorrow and I will see if it works.
 
TP-Link and fs.com responses are unexpected. A Taiwan audio review site tested QNAP SFP+ network adapter with a 1G SFP module and it worked for them. If your QNAP has got IP address from the fiber (with no other network connection), that means it works for QNAP, right?

X1 has a SFP slot, not a SFP+ slot and does not support SFP+ module.

For the X1, please note that its SFP slot is upside down - please make sure you have inserted the SFP module with the right orientation and fully, and connected the fiber before the X1 is powered on. If the switch indicates Link Up, please wait for a few minutes for the X1 to get the IP address (although it usually gets it without showing the error in our setup) - once it gets the IP address the network error will vanish.

Since you have two pairs of SFP modules and two fiber, you can swap the set for QNAP and X1 and retry.

I believe the SFP modules are compatible with both the switch and the NAS as it is able to detect the connections.
Their replies complicate the situation and I take their responses with a pinch of salt.

Yes, the X1 slot is upside down and I have already tried several times but still getting Network Error.
Will try and swap the modules later as QNAP is doing remote support to my NAS to troubleshoot. They wanna do testing using Virtual Switch settings on the NAS
 
We have not tested the $11 Cisco 2km 1310nm 1000BASE-SX SFP module you purchased.

It is something odd - it is meant to be used with multimode fiber, not the single mode fiber you purchased. I believe it is a mismatch in your setup.

We did test the more common $7 Cisco 10km 1310nm 1000BASE-LX variant which is actually cheaper despite the longer distance:
https://www.fs.com/products/12622.html

You may consider buying two pairs of these, since it's not expensive anyway.

Ahhhhhh....maybe this could be the problem.
Can you resend the link to the Cisco 10km 1310nm again? Many thanks
I bought the 2km distance cos I thought 10km was overkill lol

The X1 has been on for the last 5 minutes and Network Error is still being displayed

What transceiver type should I select - SFP-GE-L?
 
The CISCO switch arrived and I replaced the TP-Link switch.
The X1 was able to detect the network and all is working fine now

However, the NAS is still a problem.
