This section provides a description of each of the major components that comprise the
OmniStor 4700S 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 monitoring system. The monitoring system 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 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.
