Looked at features linked in the @OCC7N post, I would need to refresh my networking knowledge, at least 2 weeks training @cisco. LOL

@Tubewin. Limiting link speed to 100Mbps is the first things to do. It can be done on other device as well as mentioned above. Or by plugging a cable with two pairs wires. Not joking....

Refering to this post, a disabled port due to STP (and two other Cisco extensions) protocol will be displayed on the management page. There are 802.3az power saving options, this feature should be disabled, but is enabled by default).

There is a settings for the general power limits as well, needs more reading. Cisco recommends at least 7cm gap above ventilation slots, covering this area may trigger additional power saving. It looks very aggressive, it could be set more relaxed. It could explain problem after stacking some other device over a switch.

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.

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.

I've done everything you recommended.

I'm not keen on buying the afterdark x1 or similar products, the jcat net card xe has been working fine until the sw-10 came in.

I've tried the SW-10 in two different locations. Work station and at home. The SW-10 has been mostly non functional with only a small number of times staying connected for periods longer than an hour.

How do you disable power saving options on the LHY SW-10?

 

[OCC7N]

Pretty annoying!

What does lhy support say about this? Im a little dissapointed they don´t check these things.

I hope they cover everything regarding shipping

 

[OCC7N]

I still think it is some kind of speed issue

https://community.cisco.com/t5/switching/cbs-220-switch-100mbit-limit/td-p/4627198

What cables are you using, even though they look audiophile are they certified for the CAT6a atleast?


"The port configuration on both sides looks good to me. There must be a problem in the physical link. A broken wire or pin, miswiring, ect. Try different cables and different ports. Use other devices in the testing, too."

"Changing patchcords to Cat.6 did the trick. Thank you all for your support, it was very helpful"

This is what they said:

"Good day! I hope this message finds you well. I wanted to acknowledge your request for an RMA, and I assure you there's no need to worry. We have noted the date of your request, and the RMA procedure will be smoothly facilitated.
Please be informed that we observe the weekend and a holiday on Monday. I will connect with my engineering team on Tuesday once they are back to work. We will diligently run through troubleshooting to identify the possible root cause. Our goal is to ensure that the replacement unit we send you does not encounter a similar issue.
Your patience and understanding during this period are genuinely appreciated. If you have any questions or concerns in the meantime, feel free to reach out. We are committed to resolving this matter promptly.
Wishing you a pleasant weekend and looking forward to getting this sorted out for you.
Many thanks."

I'm worried it's going to take awhile for them to even send me a replacement...

Using cat8 neotech cables, I've tried the standard cat6 cables as well, same results as with the cat8 cables.

Why did you not choose the SW6?

and get the OCK-2 also if you are interested in masterclock.

Maybe this is what you should do for the same money as SW10

I thought the SW10 was the better product.

 

[OCC7N]

It might be. Not having any experience but if I were in you situation now. I would ask them to customize the SW6 to 75Ohm, get OCK-2 and a upgraded BNC cable.

They should make this free of charge. Close to atleast. I don´t know exactly the price difference 100dollars`?

SW6 + OCK-2 vs SW10

How do you disable power saving options on the LHY SW-10?

I looked at the Cisco documentation, a link given by @OCC7N. I don't know what features are preserved in this product which looks like OEM fo Cisco.

Is a similar manual for SW-10? Send me a link. To get to the management page, log-in to a router and find IP address of the switch by MAC address of the SW-10 which is printed on the sticker. Then point a Web browser to this IP address:
http://xxx.blabla.

Use login name and password which is also printed on the sticker. In the first step disable 802.3az power saving feature, then set link speed of relevant ports to 100Mbps. Then you can look at other power saving features.

SW-10 has no manual and no documentation. It only arrives with the unit and power cord. There was a sticker on the under side of the unit, but I don't think it had the mac address on there. Just the model and voltage.

The LHY FMC just arrived. The fmc works perfectly fine. It immediately recognized my router and received the signal from the router and showed a solid blue light the moment it was connected. I hooked back up the SW-10 into the system and it functions normally with the sfp connection as noted before. No drops in connections. There seems to be something wrong with the ethernet portion of the device on the SW-10. I'm still using the same lan cables as before into the fmc and out of the SW-10. I think the Cisco board on the SW-10 may be faulty.


Edit:
Wow nevermind. Even with the sw10 connected to fiber with the fmc, the sw10 STILL lost connection. So pretty much everything on the SW-10 is nonfunctioning.

I hope the solve the issue for you.

Im curious if they are matching the Enleum color?

Thank you.
The Enleum has more dark grey while the LHY boxes has more teal/blue mixed in with the grey, but I really do like the blue slate color of the LHY boxes. It was part of the reason why I was drawn to them. It doesn't match perfectly but they don't clash either.
