Chapter 2: Hardware
This section describes the three major components of the
flare.IQ Gen 2 system hardware – the digital processing
unit (DPU), the network switch and the redundant 24 VDC
power supply.
2.1 Main processor (DPU) –
Advantech UNO-2271G
2.1.1 Functional description
The flare.IQ Gen 2 DPU is based on a highly ruggedized,
fan-less, and modular industrial embedded computer.
The Advantech UNO-2271G edge gateway shown in figure 6
supports HDMI display, 2 x GbE LAN and 1 x USB 3.0 interfaces.
It is equipped with an Intel® Atom™ processor. 4GB of DDR3L
RAM and 32 GB of eMMC sold-state storage.
Figure 6: Advantech DPU front view
The DPU offers the following features:
• Integrated design, single-board architecture, industrial-
strength protective shell
• Intel® Atom™ E3815/E3825 processor with 4GB DDR3L
onboard memory
• 2 x GbE, 1 x USB 3.0, 1 x HDMI
• Compact fanless design
• Rubber stopper design with internal reserved screws for
2nd layer assembly
• 32GB eMMC non-volatile flash memory storage onboard
2.1.2 Connections
LAN: ethernet connector
The DPU is equipped with two gigabit LAN controllers that
are fully compliant with IEEE 802.3u 10/100/1000 Base-T.
The two ethernet ports have standard RJ-45 jacks labeled
LAN A and LAN B.
Power connector
The DPU features a Phoenix contact connector that is
compatible with 10–30 VDC input power shown in figure 7.
The added inclusion of reversed wiring protection means
reversed wiring of the ground line and power line wiring
will not damage the system. Following a forced shutdown,
wait 4 seconds before powering on the system. The power
connector must then be reconnected.

USB connector
A USB type A connector that supports plug-and-play
functionality is provided to enable service personnel to
plug in a keyboard if required. The USB interface can be
enabled/disabled in the system BIOS. A silicone rubber
dust plug is provided to increase protection of the DPU
during regular operation.
HDMI connector
An HDMI type A connector is provided for attachment of
a monitor display for use by service personnel if required.
A silicone rubber dust plug is provided to increase
protection of the DPU during regular operation.
RTC battery specification
The DPU is equipped with an RTC battery to ensure that
the BIOS and system clock settings are retained even
when the power is disconnected.
• Type: Panasonic BR2032
• Output voltage: 3 V, 195mA
Power button/power management
The UNO-2271G system has been configured to
automatically power on when DC power is applied.
Pressing and holding the power button down for
10 seconds will power off the controller, if required.
Reset button
If the DPU becomes unresponsive, gently press the
“reset” button with a paper clip to activate the hardware
reset function.
LED indication
A power status LED is provided on the DPU front panel
right above the power connector. Also, each RJ45 ethernet
interface provides 2 LEDs for network connection status,
i.e., the system’s link (green) and active (green) status.
While designed for long-term availability, Panametrics
reserves the right to change the DPU hardware provided
with a suitable replacement as required.
