Handling Static-Sensitive Devices; Removing And Installing Server Components; Removing And Installing Structural Parts - Lenovo x3250 m6 Installation And Service Manual

• Do not allow your necktie or scarf to hang inside the server.
• Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches.
• Remove items from your shirt pocket, such as pens and pencils, that could fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep
static-sensitive devices in their static-protective packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist
strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system
when working inside the server with the power on.
• 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 surface on the
outside of the server for at least two seconds. This drains static electricity from the package and from
your body.
• Remove the device from its package and install it directly into the server 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 server cover or on a metal surface.
• Take additional care when handling devices during cold weather. Heating reduces indoor humidity
and increases static electricity.
