Information about boards
Take care with the locking mechanisms (catches and centring pins) when you
are replacing boards or componen ts on boards.
Note that some compo nents on the mainboard may be very hot if the device was
in use shortly before the casing was removed.
To prevent damage to the board or the components and conductors on it, please take care wh en
you insert or remove boards. Make sure expansion boards are i nserte d straightly.
Never use sharp objects (screwdrivers) for leverage.
Boards with electrostat
ic sensitive devices (ESD) are identifiable by the label
shown.

harge static build up (e.g. by touching a grounded

• Only touch or hold t
he bo ards by the edge or, if present, at the areas
