Opening and Closing the HP ProLiant ML150 Server
This section describes how to open and close the front bezel, lower bezel, and side panel of
the HP ProLiant ML150 server.
WARNING: Before opening the server, always disconnect the power cord and unplug
cables. Disconnect the power cord to avoid exposure to high energy levels that may
cause burns when parts are short-circuited by metal objects such as tools or jewelry.
Disconnect telephone cables to avoid exposure to shock hazard from telephone
ringing voltages. Wear a wrist strap and use a static-dissipating work surface
connected to the chassis when handling components. Be sure the metal of the wrist
strap contacts your skin.
