CAUTION
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.
Wear an electrostatic-discharge wrist strap, if one is available.
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 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 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 you handle devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
