XGS-1930-28: SFP+ Ports not working in Nebula Cloud Management

I have a couple of XGS-1930-28 Zyxel Nebula Switches. I've activated 2 last year, they work fully as expected.

I recently tried to add 3 more switches and noticed the following behaviour:

When I add them using Nebula Cloud, the switch itself looks fine, but the SFP+ Ports do not work and I cannot get 10G Links up.

When I configure the same Switch with same SFPs & connection in local admin mode the SFP+ Slots work fully as expected.

When I then change back to Nebula cloud, the SFP+ Ports initially work and are shown active in Nebula Cloud, however after 2-3 mins they stop working and get dark.

Any Idea? Stefan

    Hi @sherbs ,

    Could you please share whether they are Zyxel-branded SFP+ modules, and provide model name of your SFP+ modules?

    By the way, please enable Zyxel support and provide us with the name of your Nebula organization/site here or via the private message by clinking to my account > Message.

    Hi Judy, thanks for your reply. I've enabled support as described.

    Organisation: Swisscom (Schweiz) AG
    Site Name: Itt-Ey 8, EC Product Lab @ Shared Devices Lab

    Working XGS-1930-28:

    1. eclabswitch09 - Product Lab Switch 09, 28 Port, Datacenter
    2. eclabswitch21, 24Port GE, 4x10G

    These switches are cloud managed and are equipped with Cisco 10G MM SFP+ Modules. They are working fine.

    I've used the exact same SFP+ on the new Switches and on the new ones it did not work (only in local management mode).

    The new switches are currently offline and I only will be able to connect them tomorrow 16.01.2025.
