Front Bezel Door" in this chapter.
2. Power down the server. Refer to "Powering Down the Server" in this chapter.
3. For rack-model servers only, extend the server from the rack. Refer to
"Extending the Server from the Rack" in Chapter 6, "Installing the Rack Server."
4. Remove the access panel. Refer to "Removing the Access Panel" in this chapter.
