IDCSU Components
The complete IDCSU assembly consists of an application module
and a rear connector module (CDM), together occupying a single
shelf-slot position accessible from the front and back of the
AS2000 shelf. The CDM is installed from the rear of the shelf into
the backplane. The IDCSU module is installed from the front. The
CDM is always installed first and removed last. The IDCSU front
module is installed last and removed first.
IDCSU Front
Panel
The IDCSU front panel provides LED indicators for visual alarm
indication. It is equipped with dual ejector levers to aid installation
and removal of the module. The following figures
illustrate the
front panel of the three types of IDCSU modules.
