Preparing the server blade for servicing
To service an internal server blade component, power off the server blade and remove it from the server blade enclosure.
WARNING! Before proceeding with maintenance or service on a server blade that requires physical contact with electrical or electronic components, be sure that power is removed or safety precautions are followed to prevent electric shock and equipment damage. Observe all warning and caution labels on equipment.
CAUTION: Electrostatic discharge can damage electronic components. Ensure you are properly grounded before beginning an installation procedure. For more information, see the “ESD handling information” (page 12).
Powering off the server blade
Before powering down the server blade for any upgrade or maintenance procedures, backup critical server data and programs.
Use one of the following methods to power off the server blade:
NOTE: To power off blades in a conjoined configuration, only power off the Monarch blade.
•Use a virtual power button selection through iLO 3 (Power Management, Power & Reset).
This method initiates a controlled remote shutdown of applications and the OS before the server blade enter standby mode.
•Press and release the Monarch power button.
This method initiates a controlled shutdown of applications and the OS before the server blade enter standby mode.
•Press and hold the Monarch power button for more than 4 seconds to force the server blade to enter standby mode.
