Server blade preparation
To service any internal server blade component, power down the server blade and remove it from the
enclosure.
Power down the server blade
Power down the server blade using either of the following methods:
• Press the Power On/Standby button on the server blade front panel.
Be sure that the server blade is in standby mode by observing that the system power LED is amber.
This process may take 30 seconds, during which time some internal circuitry remains active.
• Use the virtual power button feature in iLO 2.
After initiating a manual or virtual power down command, be sure that the server blade goes into
standby mode by observing that the system power LED is amber.
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 server
blade enclosure.
IMPORTANT: Remote power procedures require the most recent firmware for the power
enclosure and server blade enclosure management modules. For the most recent firmware,
refer to the HP website (http://www.hp.com/go/support
).
