Observe the following instructions to use the server safely. Failure to follow
these instructions may result in death or serious personal injury.
Do not disassemble, repair, or alter the server.
Do not look into the CD-ROM drive.

Observe the following instructions to use the server safely. Failure to follow
these instructions may cause a fire, personal injury, or property damage.
Do not lift the server only by yourself. Two people are required to lift this
server.
Do not install the server on the rack with the cover removed.
Be careful not to pinch your fingers between mechanical components.
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 top cover removed can damage
your system components. For proper cooling and airflow,
always replace the top cover before powering on your system.
Note: Your system error log will be lost, if your system ac power
source is off or disconnected.
