weight1_kg weight1_lb This symbol indicates that the component exceeds the recommended weight for one individual to handle safely. WARNING: To reduce the risk of personal injury or damage to the equipment, observe local occupational health and safety requirements and guidelines for manual material handling. These symbols, on power supplies or systems, indicate that the equipment is supplied by multiple sources of power. WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system. Powering Down the Server The server does not completely power down when the power button on the front panel is pressed. The button toggles between On and Standby. The standby position removes power from most electronics and the drives, but some internal circuitry remains active. To completely remove all power from the system, disconnect all power cords from the server. WARNING: Hazardous voltages are present inside the server. Always disconnect AC power from the server and other associated assemblies while working inside the unit. Serious injury may result if this warning is not observed. CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible power supply. This device protects the hardware from damage caused by power surges and voltage spikes, and keeps the system in operation during a power failure. CAUTION: The server must always be operated with the system covers on. Proper cooling is not achieved when the system covers are removed. To power down the server: 1. Shut down server as directed by the operating system documentation. 2. Press the power button to toggle to Standby. This places the server in standby mode changing the power LED indicator to amber. In this mode, the main power supply output is disabled. Standby does not completely disable or remove power from the system. 3. Disconnect the AC power cord from the AC outlet and then from the server. 4. Be sure that the power LED indicator is turned off and that the fan noise has stopped. 5. Disconnect all external peripheral devices from the server. Removal and Replacement Procedures 28

the server and other associated assemblies while working inside the unit. Serious injury may result if
this warning is not observed.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply. This device protects the hardware from damage caused by power
surges and voltage spikes, and keeps the system in operation during a power failure.
