RECOVER Fixing the Failure Once in a Failed Boot State
If the camera is currently in a failed initialization state (where the orange LED is on solid), the camera firmware
must be reinstalled. Upgrading to a higher TC software version will not correct a camera already in this state.
Two recovery procedures exist:
1.
Upgrade to TC 5.1.5 and use systemtools camerarescue from the admin CLI;
2.
Perform the manual recovery procedures listed under Camera Firmware Recovery Procedures Using a
PC on page 7.
Starting with TC 5.1.5, a recovery method for cameras in this failed boot state is can be run from the codec. This
recovery method can be run remotely with the camera connected as normal to the codec. This new recovery
method is initiated from the codec with the admin shell comm
, and is the
recommended recovery method. Please see the TC 5.1 Release Notes for more information:
http://www.cisco.com/en/US/docs/telepresence/endpoint/software/tc5/release_notes/tc_software_release_not
es_tc5.pdf
recovery method will take roughly 10 minutes to complete. When complete, the
codec and the camera should be fully operational.
Below is an example output of the sh
The progress of the script can be monitored if root access is enabled on the codec. Once the script is started using
running the root shell command
-f /var/log/camera-rescue.log
allows progress to be monitored. This step is not necessary for the script to function, merely to monitor progress
of the recovery.
