1.3 Precautions
This section contains safety information and advice on how to avoid damage to the
PB926EJ-S.
1.3.1 Ensuring safety
The PB926EJ-S can be powered from one of the following sources:
• the supplied power supply connected to J35
• a bench power supply connected to the screw terminals on header J34
•an external PCI bus.
Warning
Do not supply more than one power source. If you are using the baseboard with the PCI
enclosure for example, do not connect a power source to J35 or J34.
To avoid a safety hazard, only connect Safety Extra Low Voltage (SELV) equipment to
the connectors on the PB926EJ-S.
1.3.2 Preventing damage
The PB926EJ-S is intended for use in a laboratory or engineering development
environment. If operated without an enclosure, the board is sensitive to electrostatic
discharges and generates electromagnetic emissions.
Caution
To avoid damage to the board, observe the following precautions.
• never subject the board to high electrostatic potentials
• always wear a grounding strap when handling the board
• only hold the board by the edges
• avoid touching the component pins or any other metallic element
• do not connect more than one power source to the platform
• always power down the board when connecting RealView Logic Tiles or
expansion boards.
Caution
Do not use the board near equipment that is:
• sensitive to electromagnetic emissions (such as medical equipment)
• a transmitter of electromagnetic emissions.
