Do not lift the server only by yourself. Two people are required to lift this
server.

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 the system is powered off and unplug the
AC power cord from the back of the chassis. Failure to disconnect
power before opening the system can result in personal injury and
equipment damage.
The server management logic on the system board monitors and
logs system voltage changes. When powering down the 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 the
system powering down. This is normal system operation and is
required by the server management logic.
