2 Removal and Replacement Procedures This chapter provides subassembly/module-level removal and replacement procedures for system components. After completing all necessary removal and replacement procedures, verify that all components operate properly by running the appropriate diagnostic software: • For server blade components, run the Compaq Server Diagnostics utility, available from the Compaq website: www.compaq.
Removal and Replacement Procedures WARNING: Setting the server blade Power On/Standby button to the standby position removes power from most areas of the server blade. This process may take 30 seconds, during which time some internal circuitry remains active. To remove power completely, remove the server blade from the server blade enclosure. WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching them.
Removal and Replacement Procedures WARNING: To reduce the risk of shock or injury from high current electrical energy, do not reach into a server blade enclosure once it has been installed in a rack and connected to a working rack bus bar. Do not touch the power or data backplanes within the server blade enclosure once it has been installed.
Removal and Replacement Procedures 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.
