First Steps to Troubleshoot a Remote System
The following questions are commonly used to troubleshoot high-level problems in the managed
system:
1
Is the system powered on or off?
2 If powered on, is the operating system functioning, crashed, or just frozen?
3 If powered off, did the power turn off unexpectedly?
For crashed systems, check the last crash screen (see "Viewing the Last System Crash Screen"), and
use console redirection ("Supported Screen Resolutions Refresh Rates on the Managed System") and
remote power management (see "Managing Power on a Remote System") to restart the system and
watch the reboot process.
Managing Power on a Remote System
The DRAC 5 enables you to remotely perform several power management actions on the managed
system so you can recover after a system crash or other system event.
Use the Power Management page to do the following:
• Perform an orderly shutdown through the operating system when rebooting, and power the system
on or off.
• View the system’s current
Power Status —either ON or OFF .
