Troubleshooting external connections
Before troubleshooting any external devices, ensure that all external cables are securely attached to the external connectors on your
system before troubleshooting any external devices.
Troubleshooting the video subsystem
Prerequisite
NOTE:
Ensure the Local Server Video Enabled option is selected in the iDRAC Graphical User Interface (GUI), under Virtual
Console. If this option is not selected, local video is disabled.
Steps
1
Check the cable connections (power and display) to the monitor.
2
Check the video interface cabling from the system to the monitor.
3
Run the appropriate diagnostic test.
If the tests run successfully, the problem is not related to video hardware.
Next step
If the tests fail, see the Getting help section.
