Chapter 3. BladeCenter unit power, controls, and indicators

This section describes the controls and light-emitting diodes (LEDs) and how to start and shut down the BladeCenter unit.

Starting the BladeCenter unit

Important: For the LEDs on each system LED panel to function correctly, be sure to install the management module before starting the BladeCenter unit. See Chapter 2, “Installing options”, on page 13 for instructions for installing the management module.

The BladeCenter unit does not have a power switch. To start the BladeCenter unit, plug one end of each power cord into a power module on the rear of the BladeCenter unit, and the other end of each power cord into a 220-volt power distribution unit (PDU) that is plugged into an appropriate electrical outlet.

After you start the BladeCenter unit, it has ac power. The blade servers in the BladeCenter unit are connected to ac power but are not turned on. Press the power-control button on the front of each blade server to obtain full power for the blade server and start its operating system (see the documentation that comes with your blade server for information about turning on the blade server). Be sure to shut down the operating system before turning off the blade server, to avoid damaging the hard disk drives.

Notes:

1.If a power failure occurs, the BladeCenter unit restarts automatically when power is restored.

2.The blade server power button turns on or turns off the blade server if local power control has not been disabled through the management module.

3.The blade server power button turns on the blade server only if the green power light on the blade server is flashing slowly. If the light flashes rapidly, the blade server has not yet synchronized with the management module and the power button will have no effect.
