All Blus falling off ethernet network

Mark Plukas

I have an installation going in with about 30 Blu 100's, 120's, and 160's cohabitating a network with Crestron frames, touch panels, and endpoint devices. The Crestron DM is on a seperate subnet on the same physical layer.

About every 3 days every BSS Blu unit stops responding on the network. They are still passing audio but we cannot talk to them at all including getting a ping response.

If we reset the boxes they all come back on line and are happy and sound fine.

Does anyone have any suggestions for why this is happening? A wireshark trace does not show me anything unusual. Originally I found CobraNet packets flooding the network but we have subsequently taken all CobraNet and HiQNet devices off the network and the trace is much cleaner.

Have you checked the error log on the Blu's? See if any network related errors are logged.

I finally figured out that I had t oenable them first. Logging now.

We have TCPServe error messages on some of the devices.

So the problem has been coming and going. We are back into it and the BLUs are crashing nightly...all at the same time.

We are discussing pulling all the Crestron DM switchers off onto another network and isolate the system through routers.

I had the same thing happen to me with 48 devices, blu-80/32's I had to update the entire systems firmware even though it ran for 6 years without a problem. Since updating the firmware i have had 0 issues.

I'm also running on a crestron network, very similar situation.

Do you have DHCP enabled on the network and the BLU's set to get their IP address from the DHCP server? If so, check your DHCP settings to ensure that there are enough IP addresses available and your DHCP lease times are adequate.
