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 straight.
Never use sharp objects (screwdrivers) for leverage.
Boards with electrostatic sensitive devices (ESD) are identifiable by the label
shown.
When you handle boards fitted with ESDs, you must, under all
circumstances, 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.
●
Always hold boards with ESDs by their edges.
●
Never touch pins or conductors on boards fitted with ESDs.
Touchpoints for easier installation and removal of modules
and components
In order to make the installation and removal of modules and components easier, the locations for
engaging and releasing them are green coloured or marked with green dots (Touchpoints).
!
Always release and engage the modules and components marked in this way at the
corresponding locations and in the direction shown in the relevant chapter of this manual.
