Hi,

We have an M4350-40X4C that has been updated to the latest firmware and factory reset.

However, when we connect a PoE-enabled Dante speakers, it powers up (so PoE works) but it won't get any IP address.

Connecting my laptop to the same port, it gets an IP address (DHCP works) and was able to browse the configurator page.

Connecting the same Dante speakers to an unmanaged PoE switch (Netgear brand) then connecting that said unmanaged switch to the M4350-40X4C, the speakers were able to get an IP address.

We also tried connecting another unmanaged non-PoE switch (non-Netgear) but it fails to get recognized too.

To summarize:

• Dante speakers -> M4350-40X4C -> NG. Powers up but no IP
• Laptop -> M4350-40X4C -> OK. Receives IP address
• Dante speakers -> unmanaged PoE switch -> M4350-40X4C -> OK. Receives IP address
• unmanaged non-PoE switch -> M4350-40X4C -> NG. Link LEDs do not lit up

Any one has any idea what's happening here?
No configuration changes done after factory reset.
Thank you.
