This section describes the DNR-12-1G chassis and provides an overview of
common components included in every DNR-12-1G system.
The DNR-12 enclosure is a rigid mechanical structure with complete EMI
shielding (see Figure 2-4 below). Unused slots can be filled with filler panels
(filler panel diagram shown in Figure 2-6).
The DC/DC power module provides output voltages of 24, 3.3, 2.5, 1.5, and 1.2
VDC for the logic/CPU and 8 VDC to power the four cooling fans.

NOTE: Note that the rightmost module (I/O board slot 12) is 2-slots wide (to
accommodate future designs and/or custom modules).
Also note that the DNR-12 enclosure has reversible mounting flanges
designed for rack or surface mounting. Rubber feet are supplied for
desktop or tabletop mounting.
Refer to Section 4.7 on page 56 for more information about mounting
options and field connections.
Each DNR-12-1G chassis contains a power board (DNR-POWER-DC) with
status indicators and an external ON/OFF switch. Each DNR-12-1G chassis
also contains a CPU board with a dedicated GigE CPU and two Network
Interface Control (NIC) ports, one for controlling up to 12 I/O boards mounted in
the enclosure and another for diagnostics functions. Front-loading slots allow
I/O boards to be quickly and easily installed and removed, as needed.
