Handling static-sensitive devices

Static electricity can damage the blade server and other electronic devices. To avoid
damage, keep static-sensitive devices in their static-protective packages until you
are ready to install them.
Attention:
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 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
