Front Panel
The front panel is mounted onto the subrack with two quick-release
fasteners. It incorporates the cooling fans for the PAs and the PMU if these
modules are present.
Control Panel
The control panel is mounted onto
the subrack and is accessible through
an opening in the front panel. The
control panel provides some manual
control of the channels in the subrack,
can display status information for each
channel and allows the technician to
make and receive calls (refer to
“Control Panel” on page 79).
It is a technician tool rather than a user
facility.
Subrack
The 4U subrack is made of passivated steel and is designed to fit into a
standard 19 inch rack or cabinet.
It is fitted with a configurable subrack interconnect board that provides
switching and control logic. The position of a module in the rack is defined
by the socket in the subrack interconnect board to which the module is
connected by the system control bus.
