32 3 System upgrades Installing and removing the power supply WARNING! To reduce the risk of personal injury or damage to the equipment, the installation of power supply modules should be referred to individuals who are qualified to service server systems and are trained to deal with equipment capable of generating hazardous energy levels. WARNING! To reduce the risk of personal injury from hot surfaces, observe the thermal labels on each power supply module. You can also consider wearing protective gloves. WARNING! To reduce the risk of personal injury from electric shock hazards, do not open the power supply modules. There are no serviceable parts inside the module. Caution! Electrostatic discharge can damage electronic components. Make sure that you are properly grounded before handling a power supply module. Caution! Due to chassis airflow disruption, a power supply bay should never be vacant for more than two minutes when the server is powered on. Exceeding five minutes might cause the system to exceed the maximum acceptable temperature and possibly damage the system components. Caution! The power supply is only hot-pluggable if you have a redundant system with two power supplies installed. If you only have one power supply installed, before removing or replacing the power supply, you must first take the server out of service, turn off all peripheral devices connected to the system, turn off the system by pressing the power button, and unplug the AC power cord from the system or wall outlet. The server has a single 720-Watt power supply, capable of operating at 100 - 240 input volts.
