Missing Back-End on C-60 codec

Hello,

What version of software are you using?

Do you have both HTTP and HTTPS enabled or one of these disabled?  You could try enabling both and rebooting to see if this resolves your issue.

Thanks

Missing Back-End on C-60 codec

I am not able to access anything on the codec at all.  as far as I know http, https, telnet was enabled

when i try to telnet in it bumps me out

is there a back way into the codec thru serial with specific instructions to stop this message or reset?

thanks

FYI, Cisco TAC sending over a replacement codec for this error message

Question to all if you are experiencing Cisco Codecs having issues lately? 

so far within this week we have had two C60 that needed replacements

Re: Missing Back-End on C-60 codec

Hi,

Did you try to take a log from the serial port and see if the codec actually boots up properly?

Or did you try to break the boot and send the selectsw command and try selecting the other image if any.

Missing Back-End on C-60 codec

was trying to find out how to break the boot but was not informed how to,

are you able to provide that set of instructions?

have not had a chance to connect thru serial port in what that is saying as well

would love to if had time but we needed the codec to be replaced to get a working one up and running

my only concern is eventhough am able to break the boot, there is no insurance that it will not happen again, correct?

Hi,

Connect a serail cable to the codec, reboot the codec and you should see below (example from C60)

Notice the last 2 lines, follow it and you should see the "Casper >" prompt for C60.  Then you can enter the selectsw command.

Connecting via the serial will enable you to see if the codec actually boots up properly.

Missing Back-End on C-60 codec

connected thru serial but am getting garbage characters in using putty

what is the appropriate settings for serial connection?

Cisco Employee

Missing Back-End on C-60 codec

Hi,

SerialPort BaudRate

Specify the baud rate (data transmission rate, bits per second) for the COM 1 port on the codec. The

default value is 38400.

Connection parameters for the COM port: Data bits: 8; Parity: None; Stop bits: 1; Flow control: None.

You can find this in the admin guide.

So here is the log that was captured, at the end i get the login prompt, therefore am I assuming that it booted properly then?

Missing Back-End on C-60 codec

So here is the wierd part, I did nothing to the codec, all we did was to power it off for at least 24hrs and when I plugged into the serial to check that is what i got from the log capture.

Question if it hangs like before, what would I be selecting from the options? and what needs to be done to resolve the original problem?

Press 'b' to enter u-boot prompt

Press 'c' to stop autoboot:  0

Would it be option 'b' or 'c'?

Cisco Employee

Missing Back-End on C-60 codec

Hi,

so now your codec is functioning normally without the error?  I am not sure of the cause either (did you btw enter the release key previously?) since there is no log to trace.

If you want to break the boot, press 'b' then follow by 'c' and you will get a prompt.  then from there, you can enter the selectsw command.

What I am suggesting is for you to choose the other software image if you encounter the issue.  It may/may not solve what you are facing intially.

New Member

Missing Back-End on C-60 codec

no release key was entered prior to the error, the unit was left over night and next morning the error just showed up

connected a monitor to the codec thru the HDMI output to DVI monitor but am not getting any signal at all

trying to do factory default but cannot connect thru ethernet using cross-cable to the endpoint

New Member

Missing Back-End on C-60 codec

so here is an update:

eventhough i am getting the root prompt from the serial connection indicating that everything is normal

when I am accessing thru the web portal of the codec it is still getting me the "Missing Backend" message

I am able to connect to codec thru ssh and get login prompt but it bounces me out when i try to log in

so wonder if there is anything else i can do to do a factory reset or reload software from boot process?

Cisco Employee

Missing Back-End on C-60 codec

Do you mean you cannot login as admin?

Do you have an SR open for this issue?

Cisco Employee

Missing Back-End on C-60 codec

Hi,

a)can you login as admin when using serial cable?  If you can, you can do a factory default by sending the factory reset command

b)are you accessing the web via http or https

c) which TC software are you running

New Member

Missing Back-End on C-60 codec

I am not able to login as admin using serial cable but can under as root

able to access thru web portal http but gives me the "Missing Back-end" message

codec was running 3.1.4

have SR # open with TAC and they informed me they are sending me a replacement codec

think this one is totally hooped

Cisco Employee

Missing Back-End on C-60 codec

Hi,

I am interested to take a look at this codec, can you send me an email if you wish to.  Then we can probably do a web-ex?

New Member

Missing Back-End on C-60 codec

Forgot to update, received new unit from Cisco and now everything is working

was not able to trouble shoot the cause so no resolution was found on that device

Missing Back-End on C-60 codec

thx for the info!
