Components

This section provides a descriptive overview of each of the major components
that comprise the NexStor 4100FS Storage System enclosure.

Front Bezel

The front bezel houses the Status LEDs, Drive LEDs, and alarm reset button. When
removed, the user has access to the disk drives. The front bezel can be installed or
removed without interruption to system activities.

Embedded within the front bezel is the electronic package that provides the
communication with the SAF-TE processors (SEP). The SAF-TE processors control
the signals to the front panel through a smart interconnect. Power is applied to the
front bezel through a smart interconnect edge connector, where a control circuit
monitors the bezel for a proper connection. When the bezel is properly installed
and power is applied to the enclosure, the bezel is immediately energized.

Refer to “Control and Monitoring” on page 15 for details on the monitoring
functions.

Removable Front Bezel

To remove the bezel and gain access to the disk drives, use a Phillips screwdriver
to release both bezel fasteners, then grasp and remove the bezel. The fasteners
rotate one-quarter turn clockwise to lock and counter-clockwise to unlock.
