●
You must always discharge static build-up (e.g. by touching a grounded
object) before working with such components.
●
Any devices or tools that are used must be free of electrostatic charge.
●
Wear a suitable grounding cable that connects you to the external chassis
of the system unit.
●
Always hold components with ESDs at the edges or at the points marked
green (touch points).
●
Do not touch any connectors or conduction paths on an ESD.
●
Place all the components on a pad which is free of electrostatic charge.
I
For a detailed description of how to handle ESD components, see the
relevant European or international standards (EN 61340-5-1,
ANSI/ESD S20.20).
Transporting the system unit
●
Only transport the system unit in its original packaging or in suitable
packaging which protects it from knocks and jolts.
For the Japanese market, transporting the device in its original packaging
does not apply.
Only unpack the system unit at the place where you want to set it up.
●
Ask someone for help with carrying the system unit. Because the
PRIMERGY BX900 S2 system unit is large and heavy, at least three people
are needed.
●
Before lifting the system unit, remove all server blades, storage blades,
connection blades, management blades, all power supply units, fan units
and dummy modules to reduce the weight.
●
To lift or carry the system unit, mount the handles on the long sides of the
unit.
●
Only lift or carry the system unit by the handles on the long sides.
●
Never lift or carry the system unit by the handles on the front or back.
