Power down the server blade Before powering down the server blade for any upgrade or maintenance procedures, perform a backup of critical server data and programs on each server. Depending on the Onboard Administrator configuration, use one of the following methods to power down the server blade: • Use the virtual power button selection through iLO 2 for both server A and server B. This method initiates a controlled remote shutdown of applications and the OS before the server blade enters standby mode. • Press and release the server A and server B Power On/Standby buttons. This method initiates a controlled shutdown of applications and the OS before the server blade enters standby mode. • Press and hold the server A and server B Power On/Standby buttons for more than 4 seconds to force the server blade to shut down. This method forces the server blade to enter standby mode without properly exiting applications and the OS. It provides an emergency shutdown method in the event of a hung application. CAUTION: To prevent damage to the server or the operating system, always power down both server A and server B before removing the server blade from the enclosure. IMPORTANT: When the server blade is in standby mode, auxiliary power is still being provided. To remove all power from the server blade, remove the server blade from the enclosure. After initiating a virtual power down command, be sure that both server A and server B are in standby mode by observing that the system power LEDs are amber. Remove the server blade To remove the component: 1. Identify the proper server blade. 2. Power down the server blade (on page 23). Removal and replacement procedures 23
