HP ProLiant ML150 G2 Server - Installing and Replacing the System Board
|| Only authorized technicians trained by HP should attempt to repair this equipment. As the individual boards and subassemblies are complex in nature, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.
|| Electrostatic discharge (ESD) can damage electronic components. Ensure that proper grounding measures are taken before beginning these procedures.
|| Before removing any serviceable parts, determine whether the part is hot pluggable or non hot-pluggable. If the device is non hot-pluggable, the server must be powered down.
