Information about boards
Take care with the locking mechanisms (catches and centring pins) when you
are replacing boards or com ponents on boards.
Note that some components on the mainboard may be very hot if the device was
in use shortly before the casing was removed.
To pre vent damage to the board or the components and co nductors 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 electrostat
ic sensitive devices (ESD) are identifiable by the label
shown.
When handling boards fit
ted with ESDs, you must always observe the
following points:
• You must always disc
harge static build up (e.g. by touching a grounded
object) before work
ing.
• The equipment and tools you use must be free of static charges.
• Only touch or hold t
he boards by the edge or, if present, at the areas
marked green (Touc
h Points).
• Never touch pins or conductors on boards fitted with ESDs.
