EtherREGEN: Installation, Usage, Difficulty, Questions thread


Recommended Posts

I reconfigured my audio network last year with the intention of adding a EtherREGEN down the road, which I just purchased this week.  I've now discovered the TP-Link TL-SM311LM SFP's I put in my network aren't compatible (to the best of my knowledge they meet the listed requirements).  Yesterday I purchased a pair of 10Gtek ASF85-24-X2-D as they appeared to be what someone else was successfully using, but they don't work either. 

 

Try pushing the SFP transceivers in harder/deeper. Both the models you list should be perfectly compatible with the EtherREGEN. In fact that 10Gtek ASF85-24-X2-D is the one we use during final board testing on our bench with EVERY EtherREGEN unit.  I do admit that some folks have had intermittent problems with some of the TP-Link TL-SM311LM modules, but we think it is mechanical not electrical.

Beyond that I would try a different fiber optic cable for test.  And you did not say what is at the other end of that fiber feeding the EtherREGEN.  Is is a switch or router with SFP cage or is it some fiber media converter?

Thanks Superdad.  Network connectivity is provided by a D-Link DGS-1210-28P smart managed switch.  The listening room is fed fiber via a SFP in the D-Link and normally a TP-Link FMC which the EtherREGEN is supposed to replace.  I can use any combination of the four SFP's with my existing gear.  I don't think I can put the SFPs in the EtherREGEN any deeper without a sledgehammer, but I'm attaching a pic so you can confirm.  

 

Are there any settings I should look at in the switch?  I don't have another LC-LC cable on hand, since the one in question works with all the FMC's on hand it seems like an unlikely suspect.

Okay, then let's back up a little. Since there are no LEDs with SFP cages to tell you about connection, please tell us about what equipment you are connecting to which EtherREGEN RJ45 ports and what LEDs do you see above those ports when you do? Maybe the fiber connection is working fine and the trouble is something else. Since we do not know anything about your system it is hard to speculate further.

Thanks,

Thanks Alex. When the EtherREGEN is connected via SFP/fiber to the switch the lights on it for that port do indicate a connection.  When I connect a PC or my exaSound PlayPoint to the EtherREGEN out there is an amber light on and one or two flashes from the green light.

those are the ones I'm using and they do work fine

main switch used to be a TP-Link Jetstream T2500G-10TS replaced a few days ago by a MikroTik CSS610-8g-2S+

cable, though, is 9/125 OS2 single-mode duplex LC-LC

as Alex said... first time I installed the TP-Link transceiver in the EtherRegen I had to try a few times, pushing it in harder and harder, before a connection could be established

 

 

EDIT: oh.... wait... TP-Link TL-SM311L**S** are the ones I'm using, sorry 🙄

That sure sounds like you have a connection then.  What happens if you then attach a regular computer with display monitor to one of the ‘A’ side ports. Can you then surf the web?

I did test with a PC.  I don't get any connectivity through the Ethergen w/ SPF & Fiber.

Can you confirm connectivity with an RJ45 wire feed to the EtherREGEN?  Are you sure you have the Clock switch in the INT position?

Please describe your network system more fully.  Or telephone me.  Really difficult to assist you in small Q&A bits here on the forum.

Thanks.

Found a small heatsink on Ali Express which just does the job of slightly reducing the temperature as one of my ERs is not in a huge amount of space and was running hotter than my other one in a ton of free space.
