Powering the System On and Off
Powering On the System Power
1. Connect the power cables to AC input power connectors in the back of the system
and to the outlet. If 100 - 110 VAC is used, both power supplies must be connected.
2. If peripheral devices are attached that need to be turned on first, power on these
peripherals. See your peripheral guides for information.
3. Press the power button on the front panel. The green power LED will light.
4. Watch the fault LED on the front panel for any signs of trouble. See the
troubleshooting information at the end of this manual for help if necessary.
Powering Off the System Power
1. If peripheral devices are attached that need to be turned off first, power off these
peripherals. See your peripheral guides for information.
2. Press the power button on the front panel. The green power LED will turn off.
Note: The system will force a power off if the power button is held down for four or more
seconds. This method should be used only if the system has locked up. If the power is
forced off, wake events, such as Wake-on-LAN, are disabled. The IPMI “Power Off”
command functions the same way as a four-second button press. When the system power is
forced off, either the power button or the IPMI “Power On” command must be used to
power the system back on.
