Power, controls, and indicators

This chapter describes the power features, how to turn on and turn off the blade server, and what the controls and indicators mean.

Turning on the blade server

After you connect the blade server to power through the BladeCenter unit, the blade server can start in any of the following ways.

Note: Unless otherwise stated, references to the BladeCenter unit also apply to the BladeCenter T unit.

vYou can press the power-control button on the front of the blade server (behind the control panel door) to start the server.

Notes:

1.After you connect the power cords of your BladeCenter unit to the electrical outlets, wait until the power-on LED on the blade server flashes slowly before pressing the blade server power-control button. During this time, the service processor in the BladeCenter management module is initializing; therefore, the power-control button on the blade server does not respond.

2.While the blade server is starting up, the power-on LED on the front of the server is lit steady. See “Controls and LEDs” on page 8 for the power-on LED states.

vIf a power failure occurs, the BladeCenter unit and then the blade server can start automatically when power is restored (if the blade server is configured through the BladeCenter management module to do so).

vYou can turn on the blade server remotely by means of the service processor in the BladeCenter management module.
