GPEN21 Eth2 to SFP Communication not working

Sat Aug 08, 2020 5:52 am

Just received my first test set of GPEN21! So excited, then so disappointed. I'm trying to terminate ActiveE FTTH into apartments and power access points with PoE using the same device. GPEN21 fits the usage case precisely. However, during testing, we are finding that no communication is possible between the internal PoE-out ethernet port and the SFP port. I suspect this caused by software ie "port isolation." Is this a feature or a bug?

I suppose that you are trying to connect GPEN21(1) -> ETH2 to GPEN21(2) -> SFP (S-RJ01).

Right?

Regards.

Yes. I confirmed with a support case that it ins't the intended design and isn't a support operation. They may add support in SWos in a future release.

That's too bad, this is my primary use case. Already bought two GPEN21, tried to configure them, failed, and then found this forum post. Haven't found anything about this limitation in user manual, quick start guide or your website. Please document this limitation on your website and try to fix it in the next swOS release!
For now I switched to the RB260GSP to connect a LHG to Fiber.

We just deployed 20 of these today in exactly the same setup, only to find it does not work :( .. Going to have to work out a hash with a power lead and splitter now. :(

I don't get why it's like this. If it's a combo port then it should be marked as such. It looks great as a fibre to ethernet with poe
