NetGear GS250V2 unmanaged switch not working?
There’s only one ethernet (RJ45) receptacle in our small conference room so I bought a NetGear GS205v2 unmanaged switch in order to connect both the VOIP phone and the new LG smart TV to the ethernet receptacle. I did this to secure our new smart TV, wired being more secure than WiFi.
I unplugged the phone from the receptacle and plugged it into the switch. I plugged the one end of a new cat6 cable into the back of the switch and the other into the ethernet receptacle. I connected the switch's power cord into the regular electrical receptacle. The green lights on the switch lit up but the phone wasn’t connected to the internet and couldn’t make calls. When I connected the phone’s cat cable back to the ethernet receptacle it started working again.
This particular device doesn’t appear to have a dedicated uplink port. The diagram in the set up document shows the switch connected to the router which is in our server room a distance away. I thought I could connect the switch to the RJ45 receptacle and that the signal would still flow through the switch to our VOIP phone and the TV. Is that incorrect? I strongly prefer for the TV to have wired connection for security reasons.
Thanks for any feedback you can give.

Makes perfect sense to deploy a switch in this network position. Wired Ethernet is much more reliable and performing usually better.

Hard to say what happens there.
All three ports connected (the uplink to the server room, the VoIP phone, the Smart TV show active links as you said.
Can you figure out what could be special on the network port from/to the server room? Different VLAN, or port security in place?

Correct, there is no dedicated uplink port - all ports are equal.

Thank you for your responses Schumaku, greatly appreciated.
It appears that our VOIP phones might be set up in a VLAN although I wasn't able to confirm that. Another employee with a lot of technical knowledge plugged the smart TV's ethernet cable into the VOIP phone's spare RJ45 port (I wasn't even aware that the phone had one). We confirmed the wired ethernet connection via settings. This was a simple and cost-free solution. In the future if we have need to wire in other devices, I'll connect the switch between the phone and the TV and see if that works.
Thanks again. Bernadette Pesce
