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.

Notes:

1.The removable media drives, keyboard, and mouse in the BladeCenter unit are viewed as USB devices by the blade server operating system.

2.Local media tray support can be turned off preventing the blade servers from accessing the removable media drives.

3.Local KVM switching support can be turned off preventing the blade servers form accessing the keyboard, video, and mouse.

Press keyboard keys in the following sequence to switch KVM control between blade servers:

NumLock <blade server number> Enter

Where <blade server number> is the two-digit number for the blade bay in which the blade server is installed.

You will need to press the Shift key to switch KVM control when using the 28L3644 (37L0888) keyboard. If pressing the Shift key does not switch KVM control, complete the following steps:

1.Press and hold the Shift key.

2.Press keyboard keys in the following sequence: NumLock <blade server number> Enter

3.Release the Shift key.

Starting the BladeCenter unit

Important: For the LEDs on each system LED panel to function correctly, be sure to install the management module before turning on the BladeCenter unit. See Chapter 4, “Installing options,” on page 31 for instructions for installing the management module.

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 dc power. The blade servers in the BladeCenter unit are connected to dc 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).

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