Front bezel
The front bezel provides an interface for system management via
status LED indicators. The light pipes on the backside of the front bezel
allow the system status LEDs to be monitored when the front bezel is
closed. A front bezel lock is provided to prevent unauthorized access
to hard drives, peripheral devices and the control panel.
For details on how to remove the front bezel, see “To remove the front
bezel” section on page 38.
