Powering On
Caution – The power switch on the front of the server is an On/Off switch, but it
does not isolate the equipment from the AC power being supplied through the AC
power cord.
The location of the switch is shown in Figure 4-4.

Pushing the power pushbutton sends a signal to monitoring circuitry inside the
server. The switch does not directly control high-voltage AC; it controls only lowvoltage signals. When the monitoring circuitry detects that the button has been
depressed, it activates the power supply and powers up the server. Likewise, when
the server is powered up, pushing the switch powers the server down.
The main method for isolating the server from all high voltage is to physically
remove the AC power cord. If the power cord is not removed, the only other way to
isolate the server from high voltage is to open all external circuit breakers that
supply AC voltage to the equipment.
