Chapter 1 Introduction
1.1 Overview
Nuvo-2400 is a fanless shoe-box IPC with 3 PCI/PCIe expansion slots. The expansion slots
are provided for add-on cards, such as COM port cards and frame grabbers. Nuvo-2430
provides 3 PCI slots, while Nuvo-2421 provides one PCIe x4 slot with 1-lane PCI Express
2.0 signal and two PCI slots.
A convenient design of Nuvo-2400 facilitates the integration of both remote on/off switch
and the system status indicators. Corresponding signals are reserved for buttons and LEDs
outside of Nuvo-2400. And users can power on/off Nuvo-2400 externally. Furthermore,
8-channel digital input and 8-channel digital outputs are provided as an option of
Nuvo-2400. All inputs and outputs are isolated and 24VDC-rated. This makes the DI/O
compatible with many industrial sensors, indicators, coils and actuators.
Powered by Intel®Celeron®Bay Trail J1900 quad-core processor, Nuvo-2400 shows
outstanding computing power and is even more power efficient compared to those with its
predecessors. Nuvo-2400 supports dual independent displays, dual 2.5" SATAbays and
dual gigabit LAN ports with teaming and PXE. These features, together with the 3
expansion slots, maximize the flexibility of Nuvo-2400 for even more generic applications.

3.1.1 Power Button
Figure 1: Power Button
The power button is a non-latched switch for ATX mode on/off operation. To turn on the
Nuvo-2400, press the power button and the PWR LED is lighted up. To turn off the
Nuvo-2400 you can either issue a shutdown command in OS, or just simply press the
power button. In case of system halts, you can press and hold the power button for 5
seconds to compulsorily shut down the system. Please note that a 5 seconds interval is
kept by the system between two on/off operations (i.e. once turning off the system, you
shall wait for 5 seconds to initiate another power-on operation).
