Chapter 5. Installing options 31
Before you begin
Before you begin to install options in your server, read the following information:
• Become familiar with the safety and handling guidelines under “Handling
static-sensitive devices”, and read the safety statements in “Safety information”
on page 32. These guidelines will help you work safely while working with your
server or options.
• Make sure that you have an adequate number of properly grounded electrical
outlets for your server, monitor, and any other options that you intend to install.
• Back up all important data before you make changes to disk drives.
• Have a small, flat-blade screwdriver available.
• For a list of supported options for your server, refer to
http://www.ibm.com/pc/compat on the World Wide Web.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
• Each of the drive bays has either a drive or a filler panel installed.
• The cover is in place during normal operation, or is removed for no longer than
30 minutes while the server is operating.
• There is space around the server to allow the server cooling system to work
properly. Leave about 127 mm (5 in.) of space around the front and rear of the
server.
• Cables for optional adapters are routed according to the instructions that are
provided with the adapters.
• A failed fan is replaced within one hour.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To avoid
damage, keep static-sensitive devices in their static-protective bag until you are ready
to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around
you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and possibly damage the
device.
• While the device is still in its anti-static package, touch it to an unpainted metal
part of the system unit for at least two seconds. (This drains static electricity
from the package and from your body.)
• Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If your device is an adapter, place it component side
up.) Do not place the device on your system unit cover or on a metal table.
• Take additional care when handling devices during cold weather, as heating
reduces indoor humidity and increases static electricity.
