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.
The server management logic on your system board monitors
and logs system voltage changes. When powering down your
system you may experience a
1–5 second delay from the time you press the push-button
power on/off switch on the front panel and your system
powering down. This is normal system operation and is
required by the server management logic.
Operating your system with the side panels removed can
damage your system components. For proper cooling and
airflow, always replace the side panels before powering on
your system.
Contact your sales 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.
