Troubleshooting system startup failure
If you boot the system to the BIOS boot mode after installing an operating system from the UEFI
Boot Manager, the system stops responding. To avoid this issue, you must boot to the same boot
mode in which you installed the operating system.
For all other startup issues, note the system messages that appear on the screen.
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
Procedure
1. Check the system and power connections to the monitor.
2. Check the video interface cabling from the system to the monitor.
3. Run the appropriate diagnostic test.
Results
If the tests run successfully, the problem is not related to video hardware.
If the tests fail, see the Getting help section.
Troubleshooting a USB device
Before you begin
Note:
Follow steps 1 to 6 to troubleshoot a USB keyboard or mouse. For other USB devices, go
to step 7.
Procedure
1. Disconnect the keyboard and/or mouse cables from the system and reconnect them.
2. If the problem persists, connect the keyboard and/or mouse to another USB port on the
system.
3. If the problem is resolved, restart the system, enter System Setup, and check if the non-
functioning USB ports are enabled.
Note:
Older operating systems may not support USB 3.0.
4. Check if USB 3.0 is enabled in System Setup. If enabled, disable it and see if the issue is
resolved.
5. In iDRAC Settings Utility, ensure that USB Management Port Mode is configured as
Automatic or Standard OS Use.
6. If the problem is not resolved, replace the keyboard and/or mouse with a known working
keyboard or mouse.
If the problem is not resolved, proceed to step 7 to troubleshoot other USB devices
attached to the system.
