This section provides a description of each of the major components that comprise the
OmniStor 4900F Series 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 controller. The SES controller 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 21 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.
