This section provides a description of each of the major components that
comprise the NexStor 4700F Series RAID Storage System.
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 SES processes. The SES (SCSI Enclosure Services)
manages the signals to the front panel through a smart interface. Power is applied
to the front bezel through the interface edge connector, where a control circuit
monitors the bezel for 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 14 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.
