Troubleshooting Methodology
WARNING Ensure that the system is powered-down and all power sources have been
disconnected from the server prior to removing or replacing a removable media
drive.
Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Do not operate the HP server for more than 5 minutes with any cover (including disk drives)
removed. If you are hot-swapping a fan, reinstall the cover within 5 minutes to prevent
overheating. Damage to system components may result due to improper cooling airflow.
