Upgrading Your System
General Information
!
WARNING
The DC push-button on/off switch on the front panel does
not turn off the system AC power. Also, +5vdc is present on
the system board whenever the AC power cord is connected
between the system and an AC outlet. Before doing the
procedures in this manual, make sure that your system is
powered off and unplug the AC power cord from the back of
the chassis. Failure to disconnect power before opening
your system can result in personal injury and equipment
damage.
!
CAUTION
Operating your system with the top access cover removed
can damage your system components. For proper cooling
and airflow, always replace the top cover before powering on
your system.
WARNING
Avoid burns:
If the system has been running, any installed
processor and heat sink will be hot. To avoid the possibility
of a burn, be careful when removing or installing
components that are located near processors.
Contact your service representative or dealer for a list of approved optional
peripheral devices.
Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards, and
other components. You can provide some ESD protection by wearing an
antistatic wrist strap attached to chassis ground when handling system
components.
Electronic devices can be easily damaged by static electricity. To prevent
damage, keep them in their protective packaging when they are not installed in
your system.
Equipment Log
Use the equipment log form located at the end of this manual to record the
model and serial number of your system, all installed options, and any other
pertinent information specific to your system. You will need this information
when configuring your system.
