Cisco Room Navigator - Power but no network through a switch

[esmoger]

We are testing a Webex Room Bar / Cisco Room Navigator and we're running into an issue where the navigator gets power, but no network (no ip) through the switch in our conference room. This is the case whether we use DHCP or manual config.

If we plug directly into the wall, we do get a connection. Other devices plugged into the switch have a connection. The switch is a basic tp-link poe 10/100 5 port.

Plugging directly into the wall isn't an option because we need connectivity for other devices in the room and only have one port on that side of the room.

Any ideas? Thank you!

The normal configuration is to have the Room Navigator directly connected to the back of the Room Bar (see the Connecting the Cables section of the Cisco Room Bar Installation Guide).   Does the Navigator work correctly if you install it this way?

Wayne, thanks for your response. Yes, the direct connection to the bar works as expected, however we can't route the cable from the display to the conference table in the room, and draping the cable across the floor isn't an acceptable option.

Is it the case that the navigator *cannot* connect through a network switch(any switch?). For now we've connected it directly to the ethernet port on the wall and the system is working as expected, so clearly the direct connection is not the only supported option.

We have no problem buying a different switch if there's one that's known to work, just hoping we don't have to just start blindly buying them and hoping for the best.

Edit: Thanks to Micro Center's proximity to the office and their return policy, I decided to blindly try a different switch, and this one works just as expected. Netgear 8-Port Poe+ Gigabit switch. No idea what about the 2 TP-Link switches were causing connection issues, but all good now. Thank you.

Sorry if there was confusion, I wasn't saying that the direct connection was the only way, I was just trying to ascertain whether there was a problem with the Navigator, and to confirm it was actually working with the codec, had correct firmware on it/etc.

I'm glad you got it sorted though by swapping out the TP-Link and everything is now working for you.
