Servicing Hot-Pluggable Components

Hot-pluggable components can be removed and replaced without powering off the system. For information about disconnecting and connecting hot-pluggable components that require service, see "Hot-Plug Feature".

Powering Off the System

Internal Access

The system has a front bezel that must be removed to access the media tray.

Front Bezel

To remove the front bezel:

1. Grasp the front bezel on both sides near the center.

   Place your thumbs on top of the front bezel and place your other fingers at the slight indentations under the front bezel for leverage.

2. Pull the front bezel straight out toward you and set it aside.

   Press down on the top of the bezel as you pull it toward you. See Figure 12-1.
