much more obvious. The root cause is the same as with the failed camera initialization, but with different
symptoms and corrective actions.
Solution:
There is no workaround once the camera gets into the above state and replacement should be
considered. Upgrading to TC 4.2.4 or TC 5.1.3 or higher will not correct a camera that is continuously rebooting.
Corrective Actions for Failed Camera Boot Continuous Reboot:
With a serial connection to the camera (either through the camera-rescue.log file from the new recovery method
or as
Serial Recovery Procedure
on page 7) TAC is able to verify the signature of a continuously
rebooting camera. Additionally, if the orange LED at the top of the camera blinks on/off at a steady rate with
complete loss of camera control, that is a good indication the camera is continuously rebooting. Each flash of the
orange LED is an attempt by the camera to boot its firmware image, which repeatedly fails.
Unfortunately, there are no corrective actions to bring the camera back to a working state.

3. Wake from Standby
Certain Precision HD 4X cameras may also display the following after working for a period of time:
1.
System is configured for standby;
2.
System goes into standby;
3.
When system resumes from standby, camera cannot be controlled by the codec - no PTZ control from any
input device no video on self-view.
Details are documented in the following bug:
CSCts05788
PrecisionHD 1080p 4x Camera losing connectivity after going to standby
Root cause:
A high peak current consumption when the camera wakes up from standby or when powered on causes the
camera not to be detected by the codec.
Cisco has detected that some PrecisionHD 1080p 4x cameras lose connectivity to the connected codec after a
reboot or when coming out of standby. The problem has been identified and fixed and a new camera software
revision (20010) is included in TC4.2.3 and TC5.1.2 and higher. The TC software upgrade will automatically update
the camera with the newest software.
Solution:
Fixed in TC4.2.4 and TC5.1.2 and higher. The camera firmware 20010 will lower the maximum current
consumption requirement. TC4.2.4 and TC5.1.3 and higher also contains fixed camera firmware 20011 or higher
for the two other issues listed in this document.
It is strongly recommended to upgrade to either TC4.2.4 or TC5.1.3 or higher to prevent this failure from occurring.
