Handling Static-Sensitive Devices; Internal Cable Routing And Connectors - IBM x3650 M3 Installation And User Manual

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:
v Limit your movement. Movement can cause static electricity to build up around
v The use of a grounding system is recommended. For example, wear an
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
v Remove the device from its package and install it directly into the server
v Take additional care when handling devices during cold weather. Heating
