Introduction
Bengal (VL-EPMe-30) Reference Manual
5
Cautions
Electrostatic Discharge
CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board, and do
not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a grounded,
static-free surface, component side up. Use an antistatic foam pad if available.
The board should also be protected inside a closed metallic antistatic envelope during
shipment or storage.
Note:
The exterior coating on some metallic antistatic bags is sufficiently conductive to cause
excessive battery drain if the bag comes in contact with the bottom side of the Bengal.
Handling Care
CAUTION:
Avoid touching the exposed circuitry with your fingers when handling the board. Though
it will not damage the circuitry, it is possible that small amounts of oil or perspiration on
the skin could have enough conductivity to cause the contents of CMOS RAM to
become corrupted through careless handling, resulting in CMOS resetting to factory
defaults.
Earth Ground Requirement
CAUTION:
All mounting standoffs (four on PC/104 boards, eight on EBX and EPIC boards) should
be connected to earth ground (chassis ground). This provides proper grounding for EMI
purposes.
Battery Usage
CAUTION:
If you are using a CBR-5015 paddleboard with the Bengal board, do not connect an
external battery using the J8 connector. Connecting two batteries to the Bengal board
will damage the batteries and may possibly damage the Bengal board and the CBR-
5015 paddleboard as well.
