To reduce the possibility of damage from electrostatic
discharge, observe these precautions.
Attention: Static electricity can damage the compute node and
other electronic devices. To avoid damage, keep static-sensitive devices
in their static-protective packages until you are ready to install
them.
- When you work on a chassis that has an electrostatic discharge
(ESD) connector, use a wrist strap, especially when you handle modules,
optional devices, or compute nodes.
To work correctly, the wrist strap must have a good contact at both
ends (touching your skin at one end and firmly connected to the ESD
connector on the front or back of the chassis).
- Limit your movement. Movement can cause static electricity to
build up around you.
- Handle the device carefully, holding it by its edges or its frame.
- Do not touch solder joints, pins, or exposed circuitry.
- Do not leave the device where others can handle and damage it.
- While the device is still in its static-protective package, touch
it to an unpainted metal part of the chassis or any unpainted metal
surface on any other grounded rack component in the rack in which
you are installing the device for at least 2 seconds. This drains
static electricity from the package and from your body.
- Remove the device from its package and install it directly into
the compute node without
setting down the device. If it is necessary to set down the device,
put it back into its static-protective package. Do not place the device
on the compute node cover
or on a metal surface.
- Take additional care when you handle devices during cold weather.
Heating reduces indoor humidity and increases static electricity.
