Before you begin
Before you begin to install options in the computer, read the following information:
v
Become familiar with the safety and handling guidelines specified under
“Handling static-sensitive devices,” and read the “Safety information” on page
103. These guidelines help you work safely while working with the computer or
options.
v
Make sure that you have an adequate number of properly grounded electrical
outlets for the computer, monitor, and other options that you intend to install.
v Back up all important data before you make changes to disk drives.
v
Have a small, flat-blade screwdriver available.
v For a list of supported options for the computer, refer to
http://www.ibm.com/pc/us/intellistation on the World Wide Web.
System reliability considerations
To help ensure proper cooling and system reliability, make sure:
v
Each of the drive bays has a filler panel installed.
v
The cover is in place during normal operations, or is removed for no longer than
30 minutes while the computer is operating.
v There is space around the computer to allow the computer cooling system to
work properly. Leave about 127 mm (5 in.) of space around the front and rear of
the computer.
v
Cables for optional adapters are routed according to the instructions provided
with the adapters.
v A failed fan is replaced within 48 hours.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and the system. To
avoid damage, keep static-sensitive devices in their static-protective packaging until
you are ready to install them.
To reduce the possibility of damage from an 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 frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v
Do not leave the device where others can handle and possibly damage the
device.
v
While the device is still in its static-protective package, touch it to an unpainted
metal part of the computer for at least two seconds. (This discharges the static
electricity from the package and from your body).
v Remove the device from its package and install it directly into the computer
without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If the device is an adapter, place it component side
up). Do not place the device on the computer cover or on a metal table.
v
Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
