Information about boards
Take care with the locking mechanisms (catches and centring pins) when you
are replacing boards or components on boards
To prevent damage to the board or the components and conductors on it, please take care when
you insert or remove boards. Make sure expansion boards are inserted straightly.
Never use sharp objects (screwdrivers) for leverage.
Boards with electrostatic sensitive devices (ESD) are identi fi able by the label
shown.
When handling boards fi tted with ESDs, you must always observe the
following points:
• You must always discharge static build up (e.g. by touching a grounded
object) before working.
• The equipment and tools you use must be free of static charges.
• Only touch or hold the boards by the edge or at the areas marked green
(Touch Points).
• Never touch pins or conductors on boards fi tted with ESDs.
• Disconnect the mains plug before inserting or removing components.
• When installing components, use a suitable earthing cable to connect
them to a bare metal (i.e. unpainted) part of the system unit which does
not carry a live voltage.
• Place down all components on a surface which is free of static charge.
A detailed description of how to protect sensitive components from the
effects of electrostatic discharge can be found in the relevant European and
international standards (EN 61340-5-1, ANSI/ESD S20.20).
