UCM ETH03

[martin.wonders@unn.ac.uk]

Hi,
I\'ve just purchased a UCM eth03 but it is not being detected by the server manager, all the lights are as they should be. Just spent hours going through the manuals with no luck, quite disappointing that these things don\'t work out of the box!, any help with this will be gratefully received.

Usual advice would be to ensure you are running the latest Eth3 firmware first.

Hi Julien,
Thanks for the quick response, but how do I upgrade the firmware if the ethernet interface is required to upgrade the firmware? My connection to Comfort has until a couple of weeks ago been through an eth02 interface which suddenly stopped working so I\'ve bought the replacement eth03 which isn\'t working either.
Thanks
Martin

Oh sorry I misread;  thought you couldn\'t connect to Comfort.

Try disabling the firewall on your PC for a few secs; if you can then see the ETh3 then that may point to need a port opened.

No problem, I\'ve reset the Eth03 and used the factory set ip 192.168.0.109 and isolated a LAN, I now get a successful ping to the factory IP and have managed to update the firmware for the Comfort Utra and the ET03 UCM to the latest versions but still the server manager does not pick up the UCM?
I have the firewall disabled completely and have run a wireshark capture to determine if the network manager is running a scan and it isn\'t so it looks like it could be the network manager software. I can communicate with comfort on my isolated network so just need a way to disable DHCP and enter a static IP to the UCM without the network manager, any Ideas?
Thanks
Martin

Also check that you are running the latest Server Manager and that you don\'t try and use the old DS Manager to discover the Eth03. If you can ping it then connectivity is fine. Check that you see a UDP port 30303 broadcast and reply in the trace.

Here\'s what mine looks like for example.

If you are using wireshark, check if the software is sending to port 30303 mentioned here http://www.comfortforums.com/forum113/3823.html




The screenshot shows sending to port 30303 and reply on UDP

Usually it is the router that blocks the port or firewall

Try connecting the ETH03 directly to the PC Lan port and run CS Manager

Tried it on two PCs with firewalls off, plugged into an isolated LAN (i.e. switch with ETH03 and PC), can ping the factory set 192.168.0.109 and can connect to comfort through the ETH03 on the isolated LAN to configure and have been able to update to the latest firmware. 
Server manager is the most up to date version and with wireshark running with a filter of (udp.dstport == 30303 || udp.srcport == 30303) I get nothing so it seems that the Server manager is doing nothing.
As soon as I bring the rest of the network up with the sky router I can no longer ping the factory default ip. Starting to pull my hair out! Help!

Ok the last example helped re: virtual machine, disabled the VM network card and bingo it\'s running. Thanks for the help all, much appreciated.
