Chapter 2. Power, controls, jumpers, switches, and indicators This chapter describes the power features, how to turn on and turn off the blade workstation, and what the controls and indicators mean. This chapter also identifies the system board jumpers and switches. Turning on the blade workstation After you connect the blade workstation to power through the BladeCenter unit, the blade workstation can start in any of the following ways: v You can press the power-control button on the front of the blade workstation (behind the control panel door, see "The control panel buttons and LEDs" on page 12) to start the blade workstation. Notes: 1. Wait until the power-on LED on the blade workstation flashes slowly before you press the blade workstation power-control button. While the service processor in the management module is initializing, the power-on LED does not flash, and the power-control button on the blade workstation does not respond. 2. While the blade workstation is starting, the power-on LED on the front of the blade workstation is lit. See "The control panel buttons and LEDs" on page 12 for the power-on LED states. v If a power failure occurs, the BladeCenter unit and then the blade workstation can start automatically when power is restored, if the blade workstation is configured through the management module to do so. v You can turn on the blade workstation remotely by using the management module. v If the blade workstation is connected to power (the power-on LED is flashing slowly), the operating system supports the Wake on LAN feature, and the Wake on LAN feature has not been disabled through the management module, the Wake on LAN feature can turn on the blade workstation. v The thin client can turn on the blade workstation remotely. Turning off the blade workstation When you turn off the blade workstation, it is still connected to power through the BladeCenter unit. The blade workstation can respond to requests from the service processor, such as a remote request to turn on the blade workstation. To remove all power from the blade workstation, you must remove it from the BladeCenter unit. Shut down the operating system before you turn off the blade workstation. See the operating-system documentation for information about shutting down the operating system. The blade workstation can be turned off in any of the following ways: v You can press the power-control button on the blade workstation (behind the control panel door, see "The control panel buttons and LEDs" on page 12). This starts an orderly shutdown of the operating system, if this feature is supported by the operating system. Note: After you turn off the blade workstation, wait at least 5 seconds before you press the power-control button to turn on the blade workstation again. © Copyright IBM Corp. 2007 11
