Important notes Notes on safety
When you handle components fitted with ESDs, you must observe the following
points under all circumstances:
●
You must always discharge yourself of static charges (e.g. by touching a
grounded object) before working.
●
The equipment and tools you use must be free of static charges.
●
Shut-down the system and remove the power plug from the power socket
before inserting or removing boards containing ESDs.
●
Always hold boards with ESDs by their edges.
●
Never touch pins or conductors on boards fitted with ESDs.
●
Use a grounding cable designed for this purpose to connect yourself to the
system unit as you install/deinstall the board.
●
Place all components on a static-safe base.

You will find a detailed description for handling ESD components in the
relevant European or international standards (EN 61340-5-1,
ANSI/ESD S20.20).
Notes about boards
●
During installation/deinstallation of the board, observe the specific instruc-
tions described in the service supplement for the respective server.
●
Shut-down the system and remove the power plug from the power socket
before you make modifications on an installed board.
●
To prevent damage to the board, the components and conductors on it,
please take great care when you insert or remove boards. Take great care
to ensure that extension boards are slotted in straight, without damaging
components or conductors on the board, or any other components, for
example EMI spring contacts
●
Be careful with the locking mechanisms (catches, centring pins etc.) when
you replace the system board or components on it, for example memory
modules or processors.
●
Never use sharp objects (screw drivers) for leverage.
