C40's Network Dead After Restart

I was in the process of updating the software (TC5.1.1) on a Profile 42 (C40 CODEC), I entered the new key code and the system needed to restart.  After the reboot I could not see the device on TMS. After talking with the location the device says Not Registered (No LAN) which I thought was odd.  I'm at the site now and the network connection is fine and I triple checked every thing.  I rebooted the system again and the touch panel works fine and if you watch the two network ports on the C40 the #1 for the LAN will light up until the device gets almost started and then goes blank.  Any ideas on what is going on or why this happened?  I'm worried we have a hardware failure with no access to TAC on this device.

Could I update the software via USB on the C40 and see if this resolves the problem?  Thanks for helping out the newbie again.

Hi Dave,

can you try to access this C40 using its serial port ? you can then check the xconfig and xstatus network  and also  check the vlan settings on this unit.

other way to check device ethernet port is by direclty connecting this C40 to your laptop using a crossover cable and then assigning ip on laptop ethernet card in same ip range as codec and then try to ping it.

try giving it hard reboot and check if there is any difference

Is there a certain program you need to go the serial route?  I assume a USB to serial cable? 

I can try the crossover route too and see.

The hard reboot would simply physically powering it down, let it sit for a bit then restart?  I just want to make sure we are on the same page.

Hi Dave,

just to confirm, is this device on a boot loop ??

means, it is rebooting after cisco logo on screen continously, never reaching wallpaper screen ??

No, everything boots up fine we just do not have a network connection.

Hi Dave,

Please let me know what do you mean by entered the code for upgrade.

Did you upload the software file only?

Please run the command on putty-

xcommand systemunit releasekey list

and check if release key is present for TC5 or not.

if not, please enter the release key and reboot the codec again to check.

I was provided new release codes due to a possiable security problem with the old TC releases.  I entered the code for TC6.3 which needed a reboot, afte this the problem started. There was no software update performed, that was my next step.

Sorry I have never used putty before, but could not get a connection.  If I look on TMS there are codes for TC5.1.6 and TC6.0.1 listed.

Re: C40's Network Dead After Restart

What is the codec showing on the screen?  Can you see the System Information screen to see if it has picked up an IP address from the network, or can you set one via the menus?  Is the device still connected to the switch (has it been inadvertently disconnected by someone, or faulty cable)?  I'd be trying the simple things like that before going to the serial connection and playing with the CLI

Re: C40's Network Dead After Restart

I can see and run though the menus when I was physically at the site.  No IP address shown on the screen and I did check all of the cabling back to the patch panel and switch.

C40's Network Dead After Restart

Hey Dave,

I am curious of a few things. What type of switch is the profile system connected to? If you connect to to the switch, do you see any errors on that switchport? Does the switch you are using support CDP and can you see the codecs CDP information on the switchport?

If you have a db9 serial to usb cable, you can connect to the com port on the Codec and do some more testing to see if the system's nic is active or not.

First connect to the codec via a serial cable. Then connect to the codec with a speed of 38400, 8 bits, 1 stop bit, no parity. Turn on the codec and wait for it to boot up and get to the login prompt. Now login as root (if root is not enabled login as 'admin' and once you are in issue the command 'systemtools rootsettings on' to enable root. then type logout and re-login as root). Once you are in as the root user, issue the command 'ifconfig' to check the network port. Also try to ping the loopback address on the codec ' ping 127.0.0.1'. What are the results of these tests? Also can you get the output from the log file located at /var/log/console.log. Let us know!

Re: C40's Network Dead After Restart

I'm not sure what exact model the switch is but if I had to guess I would say a Cisco Catalyst 3750 48 port PoE.  I will have to contact our network team to see if the switch has a bad port, but I did move it to a new switch and new port to hope with eliminating the problem.

I will see if I can get back to the location today connect via the com port.

How do you kill th loop back ping??

Here are a few screen shots on what I have found.  I may end up having the CODEC in my office to help with speeding up this process.

The ping looks OK.

Any thoughts?  Could a factory reset be another option?

C40's Network Dead After Restart

Thats already a quite long discussion here, but I am not sure if the core elements are addressed.

If you could let us know a bit more about your network, like what kind of switches and network

configuration fo you use. Is there any CDP, (Voice)VLANs, Port security, DHCP, ....

What ip would you expect the endpoint to have?

The endpoint has two network interfaces, the orange marked Ethernet 1 (=eth0) and the

Ethernet 2 (=eth1). The network has to be connected to the Ethernet 1.

The touchpanel has to be connected to Ethernet 2 or on a switch connected to Ethernet 1,

so that the endpoint can still reach the network.

Can you get an IP via DHCP if you connect a different device/computer to this network port?

The endpoint itself if reset to factory default will loose its pre configured network settings

and fall back to DHCP and depending on the used software there might be some changes

regards VLANs.

If the system is still listed in TMS you might be able to see the status and configuration in the

extended configuration tab. That can be helpful as well.

I could picture that there was a fixed ip address set up and or changes regards VLAN and CDP.

If you look at your ifconfig output, eth0 has no ip and sure, if there is no ip you will not be able to connect to it.

127.0.0.1 / the loop back interface is nothing what has any use for you here.

I went over and removed the C40 to bring it back to my office for testing.  I power cycled the device before it was removed tried the current and secondary network cables with no luck again (note the green/orange lights by the port were always dead never illuminated).  In my office I powered the device up and it worked 100% and connected just fine on the network.  I updated to TC7.0 took the C40 back to the other location and it worked fine for the test calls I performed.  Just odd??

Re: C40's Network Dead After Restart

Port Security on the switch?

Some failed authentication feature like 802.11x... etc

Investigating the config of the switch really is your next step to know what is in play on the network.

Re: C40's Network Dead After Restart

I will talk with the network guys and see.  It's working fine now though.
