Keep it on and let the clock settle....

Shutdown everything else. Wait 2min and turn on everything including the routher and modem

I will try that again when I get home. Appreciate the suggestions.

Wait are your JCAT running at 100MB????

 

[OCC7N]

Check the speed between the devices....Etherregen is only 100MB on one side, if it works with JCAT something tells me your JCAT is running 100MB locked auto-negotiation.

Bridged the JCAT or?

Yes, I believe the speed is 100mb.

I've tried connecting the SW-10 from the router directly into the jcat ethernet card, without the Etherregen. It worked for half a minute before it lost the ip and refused to connect. It absolutely refused to work that way.

I already purchased the LHY FMC a few days ago, should be coming in sometime next week.

The Etherregen doesn't sound bad to me, but I respect your opinion.

I just can't stand the issues that the SW-10 is having. It's mind boggling.

The pictures show the only way it will connect to the ip.

Will connect to the ip:
Modem -> Router -> SW-10 -> Etherregen -> Jcat Ethernet card (not stacked)
Modem -> Router -> SW-10 (sfp) -> Etherregen (sfp) -> jcat

Will not connect to the ip:
Modem -> router -> SW-10 -> Jcat card
Modem ->SW-10 -> Etherregen -> jcat
Modem -> router -> sw-10 (w/bnc out) -> etherregen(bnc in) -> jcat
Modem -> router -> sw-10 -> etherregen ->jcat (when stacked on top of each other, I have no idea why it doesn't work when stacked)

I've reset the router, modem, computer, and sw-10 switch dozens of times, it did not help.

Gee that all sounds terribly frustrating.

A switch should just work with the network connecting almost immediately after being inserted/switched on, as it does with both my LHY SW-8 and Netgear switches, every time (exception being HQplayer on my server handshaking with the network renderer in my DAC which can take 20 secs or so, and sometimes a reset restart of HQP and the DAC).

The fact it works for you for 30 secs then stops sounds particularly suspect and makes me wonder about your particular unit. Not surprised it doesn't work plugged directly into your modem, would think it'd need a router interposed to assign IP addresses etc - indeed I see Beatechnik say this on their product page.

More generally I've not read of anyone else having such issues with the SW-10. And for what it's worth to you (probably little till you resolve this) I've not personally had any issues with several other LHY products I have, and from my correspondence with LHY/Beatechnik they seem pretty responsive /keen to ensure customer satisfaction.

To eliminate the possibility of a JCAT incompatibility (incl speed) thing, I second OCC7N's suggestion of trying the motherboard. Though given the SW-10 is based on a Cisco business switch I'd expect it to negotiate down to 100Mbps if it can't handshake or maintain a connection at 1Gbps. Indeed I daresay the majority of audiophile streamers would be limited to 100Mbps at present so 100Mbps compatibility has to be a given - I'd hazard a guess many if not most SW-10 owners are using it with 100Mbps streamers or audiophile network cards.

Does your JCAT work plugged directly into your router, and if so is the router gigabit or 100Mbs?

Thanks for your response. Yeah, it's been a extremely frustrating experience.

I have not checked to see if the jcat worked directly connected into the router. It has always had the etherregen in between. I can check when I get home.

Business grade switch has an optional feature to detect multiple path and block frames that could travel across LAN in a loop infinitely. In the simple star configuration it never happen, but is possible with multiple adapters in the bridge mode. However I don't think it is a case.

Gigabit Ethernet mandatory feature is compatibility with Fast Ethernet. Switch is responsible for transfering frames from the slow to the fast port and in reverse. Store and forward architecture (all consumer grade and most of business switches) make it easy. It means the entire frame is buffered before forwarding. There is a delay, with a fixed minimum.

For audio purpose someone could come with an idea of forwarding frames as soon as reading a header. It create problem when 1Gbit port is a destignation. Such frame will be truncated (as soon as new data do not arrive in time) and subsequently being discarded by the recipient. Possibly more problems. Those who try to modify stock firmware should predict such scenario.

A work around is to set a port manually to a slow link speed or use cable with only 2 pairs of wires which would block negotiation of 1Gbit speed. It is worth to try in this situation.

This worked. Thank you occ7n. I guess when I move this around I need to turn off everything besides the switch and turn it back on.

 

[Tubewin]

And its back to not connecting .

 

[Jake2]

Damn. Was hoping you were sorted. Sounds like something in the connection, or switch, is unstable.

Perhaps still try those other things we've suggested and if they all work seamlessly /stably apart from those with the SW-10 as the last step in the chain to the server it simplifies the message back to Beatechnik seeking resolution.

the moment I remove the sw10 from the chain and connect the etherregen from the wifi router and etherregen into the jcat ethernet card, it works immediately.

 

[Tubewin]

This is the second day and another night of just moving this box around for 5 hours. I’ve contacted beatechnik yesterday, but it doesn’t look like they are trying to take it back…. I’ve asked for the rma twice now…

 

[Tubewin]

It must be an issue with the wifi router and the network switch.

 

[Tubewin]

I just replaced the wifi router. It didnt fix the issue. Well thanks everyone for the help. It’s most likely the unit.

 

[OCC7N]

What JCAT do you have…NET XE?

Please set the speed at auto-negotiation.

Did you try motherboard. Isolate the problem.

I have had a lot of problems because of cables and speed/100/1000

The switch is not your ordinary audiophile switch....

Administration guide:
https://www.cisco.com/c/en/us/td/do...-220-admin-guide/get-to-know-your-switch.html



My recommendation is.

1. Reset and turn on the router so its ready for DHCP to the units.
2. Connect SW10 with a proper atleast CAT6a nothing less.
3. Don´t connect anything to the SW10 other than being able to receive the "IP address" from the Router.
4. Download the app and see if you can reset all settings on the switch.
5. After resetting make sure your computer is running speed at 1G(or auto-neg) both JCAT and motherboard so you can try between them
6. Connect the JCAT* with a proper atleast Cat 6a cable.

*Make sure your JCAT is in Bridge mode

I have no further experience other than let the clock settle.

Use this as an replacement for both the JCAT and Etherregen. The LHY FMC is a good match for optical input on the SW10 I believe.
https://www.adark.co/products/afterdark-constellation-giesemann-x1-ethernet-server-adapter

Chain: - > ISP - MODEM - Router - LHY/FMC - SFP - SW10 - ETH CAT6a/7/8 - Afterdark X1(clock input from SW10/75ohm).

you could also run it optical straight to the source with this and master clock

I am not a believer yet of optical I don´t like data leaving its "form" just to eliminate noise. I rather look at the start of the chain first.
