Server Blade Components
Use the procedures in this section to perform service events on ProLiant BL20p server blades.
Server Blade Preparation
To service any internal server blade component, you must power down the server blade and
remove it from the server blade enclosure.
CAUTION:
Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. For more information, refer to
the “Electrostatic Discharge Information” section in this chapter.
System power in server blades does not completely shut off with the front panel Power
On/Standby switch or Integrated Lights-Out (iLO) Virtual Power Button feature. The
function toggles between on and standby modes, rather than on and off. The standby position
removes power from most electronics and the drives, but portions of the power supply and
some internal circuitry remain active.
To service internal server blade components:
1. Identify the proper server blade in the server blade enclosure.
2. Remove power from the server blade in one of the following ways:
— Use the Virtual Power Button feature in the iLO Remote Console to power down the
server blade from a remote location. Be sure that the server blade is in standby mode
by observing that the power LED is amber.
— Press the Power On/Standby button on the front of the server blade. Be sure that the
server blade is in standby mode by observing that the power LED is amber.
