The scope covers the detailed electrical and connector specifications defined for the interoperability of the OPS, as well as the mechanical and thermal specifications that need to be adhered to when designing the physical system and its thermal solution.
Note: Throughout this document the digital signage computing system will be referred to as
the “Pluggable Module”.
Throughout this document the 80pin JAE TX24A/TX25A series connector will be referred to as the “JAE connector”.
Dimensions shown in all figures are in unit mm.

Introduction
feature interfaces are being routed through this set of connectors to provide a functional system level computing solution for digital signage.
The Pluggable Module consists of a computing board (for example, EPIC size board or smaller) in a wrapper chassis. The JAE connector enables plug and unplug mechanism between the Pluggable Module and the docking board inside the display panel.
Note: The connector does not support hot plug function. If such a requirement is needed,
developers can choose to design the power-on self-start function and hot plug
protection circuit to prevent any damage to the pluggable module and display panel docking board, which may be caused by the hot plug usage model.

This pin shall be Open Collector and pull up to +3.3V on the docking/control board side. High: Pluggable board power off state Low: Pluggable board power on state See Figure 4 for illustration example. Pluggable Signal ON: This is meant for signal initiation to power ON or boot up the Pluggable Module. PS_ON# shall be asserted at least 500 ms after power is delivered from PSU to the board via the JAE connector (G3 to S5 state). Pull up to +3.3V on the pluggable board. A pulse width present on the PS_ON# shall be detected and responded within 200 ms to ensure successful operation. Use case: Power Button initiation from the panel control board to the Pluggable board via, for example, IR remote control ON. The PWRBTN# pin on the Intel ICH/PCH can be utilized for this purpose. PWRBTN# has a 16 ms of internal debounce logic. External debouncing circuit is not required. Refer to the respective platform design guide and chipset datasheet. +If the pluggable board present state is S5, the transitions start as soon as the PWRBTN# is pressed (but after the debounce logic), and does not depend on when the Power Button is released. +If pluggable board present state is S0-S4 and if PWRBTN# is held low for at least four consecutive seconds, this will initiate unconditional transition to S5 state. **This timing spec applies only for Intel ICHx series and 5 series chipset. For other platforms, refer to the respective component Power Button spec. 73 PS_ON# I Digital Signage Open Pluggable Specification (OPS) Electrical, Mechanical, and Thermal Specification 18

High: System Fan OFF Low: System Fan ON *1 Note *1: This signal shall be triggered ON by the thermal management system (EC) in the pluggable module only when needed. Use case: In situation where display panel is in standby mode and the Pluggable Module is still operating (e.g., remote maintenance, etc.), system fan solution may still be needed and since display panel is in standby mode there is no way to control the system fan. This pin therefore serves as an option to trigger the system fan to operate when necessary. 71 CEC I/O 50 SYS_FAN O 2.4.7 Reserved

3.3 The Lock Holes on the Pluggable Module
There are two lock holes on each side of the Pluggable Module. These holes, mated with the matching lock pins from the guiding rail on the display system, provide locking effect to the module during docking/undocking process. Figure 9 shows the dimension and the location of these locks holes on the Pluggable Module. Guiding rail
implementation has to adhere to the location of the lock holes, as well as the thickness and depth of the Pluggable Module.

3.4 Rating Labels
Rating labels should not be placed on keep-out-zones on the Pluggable Module due to potential interference with the guiding mechanism that guides the module box during the mating/un-mating process. The dimensions of these keep-out-zones are shown in Figure 10. Also, the rating labels should not be placed on the ventilation holes on the heat sink and the DIMM service windows, as that would prevent air intake to the components.

3.6 Venting Area on the Display Panel for the Pluggable Module
Vent holes must be opened at the location of the Pluggable Module so that air can enter the heat sink on top of the module. It is required that the venting area should at least cover the Pluggable Module so that the entire top surface is exposed to ambient air. Figure 12 shows the minimum venting area for the Pluggable Module in a reference display panel. Note that Figure 12 is only an illustration for the venting area for
modules that plug in from the bottom the display panel. For modules that plug in from the side, the orientation of the venting area should follow accordingly as shown in Figure 13.

Thermal Management for the Pluggable System
The thermal management of the Pluggable Module must be handled carefully to
ensure all components comply with the thermal specifications. This section illustrates a simple wind tunnel test to quantify the airflow needed for module cooling. Figure 14 shows the top view of an empty wind tunnel. (The module should not be present in this test.) There is an opening at the top where air from the surrounding enters the wind tunnel. The Free Area Ratio (FAR) for the opening is set to 0.6 for reference. It is
imperative that all other surfaces be sealed off so that air enters the wind tunnel only from the top opening. Figure 14 also shows an imaginary plane located approximately at the mid-section of the wind tunnel. It is required that the average airflow speed through this plane is 1.2m/s to ensure sufficient airflow is provided to the module for forced convection cooling.
Figure 15 shows the wind tunnel dimension and the location of the module. The
module can be tested in an environment temperature not higher than 45°C to ensure all components pass the thermal requirement. It is the responsibility of module designer to ensure all components comply with the thermal specification.

4.2 Thermal Consideration for Display Panel
The display panel should be designed in such a way that there is sufficient airflow provided to the Pluggable Module within the panel in the desired operating
environment. The operating temperature and airflow being provided to the Pluggable Module are keys to good thermal design. While there are vast varieties of possible display panel design, it is hard to achieve a point solution that satisfies the Pluggable Module and display panel thermal requirements. However, the display panel design must ensure the thermally critical components in the Pluggable Module are meeting their thermal requirements.
To ensure the display panel is thermally friendly to the Pluggable Module, a dummy module is available for thermal test. Contact an Intel representative for further details.
