Hardware Preparation and Installation

2.1 Environmental and Power Requirements

2.1.1 Environmental Requirements

The following module environmental requirements must not be exceeded.
Operating temperature refers to the temperature of the air circulating around the module and not the component temperature.
The following table provides the environmental requirements for the module.
Chapter 2
Table 2-1 Environmental Requirements
Requirement Operating Non-Operating
Temperature
Humidity
Vibration Sine (10mins/axis) 5G, 15 to 2000Hz
Vibration Random (1hr/axis) 0.04g2/Hz, 15 to 2000Hz
Shock 30g/11mS(half sine)
Altitude -60 to 4000 m ASL
Thermal Requirements
A standard passive heat sink can be provided by Artesyn; 12 CFM system airflow volume (at 71oC) is needed for the heat sink to keep sufficient cooling to the module. Contact your Artesyn sales representative for detailed thermal information.

2. Check for damage and report any damage or differences to customer service.
3. Remove the desiccant bag shipped together with the enclosure and dispose of it according to your country’s legislation.
Improperly disposing of used products may harm the environment. Always dispose of used products according to your country’s legislation and manufacturer’s instructions.
The product is thoroughly inspected before shipment. If any damage occurred during transportation or any items are missing, contact customer service immediately.

2.3 Installing and Removing the Module on the Carrier Board

The heat sink is assembled to the module before the procedure below:
Installing the COM module on the carrier board
1. Line up the board-to-board connector of the module assembly with the board-to-board
connector of the carrier board.
2. Make sure that the inter-connectors are properly aligned and that the five standoffs on the
module have contact with the top of the carrier board.
