Under certain rare conditions, the video output from the CMM might be distorted, colored incorrectly, or not visible. This occurs when a video monitor is connected to the video port on the multiport cable.
Workaround
This condition is benign, and if the video display is acceptable, you can ignore it.
Connect to the video display using Oracle ILOM.
For instructions for using Oracle ILOM to view the video display, refer to Communicating With the ILOM and the System Console in Sun Fire X4800 Server Installation Guide.
