v
You do not operate the server without the air baffles installed. Operating the
server without the air baffles might cause the microprocessor to overheat.
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
you.
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
metal part on the outside of the server for at least 2 seconds. This drains static
electricity from the package and from your body.
v
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.
v
Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
Returning a device or component
If you are instructed to return a device or component, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to
you.
Removing and replacing server components
This section provides information for removing and replacing components in the

Removing and replacing consumable parts and Tier 1 CRUs
Replacement of consumable parts and Tier 1 CRUs is your responsibility. If IBM
installs a consumable part or Tier 1 CRU at your request, you will be charged for
the installation.
