Upgrading Your System
General Safety Information
Warning
The DC push-button on/off switch on the front panel does not
turn off completely the system AC power. +5vdc is present on
the system board whenever the AC power cord connects the
system to 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 the power cord before opening your
system can result in personal injury and equipment damage.
Caution
Operating your system with the top covers removed can dam-
age your system components.
For proper cooling and airflow, always replace the top covers
before powering on your system.
Warning
Avoid burns: If the system has been running, any installed pro-
cessor and heat sink on the processor board(s) will be hot.
To avoid the possibility of a burn, be careful when removing or
installing components that are located near processors.
Contact your sales representative or dealer for a list of approved optional peripheral
devices.
