If there is no response when you press the KVM select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade workstation. Media-tray select button: Press this button to associate the shared BladeCenter unit media tray (removable-media drives and front-panel USB ports) with the blade workstation. The LED on the button flashes while the request is being processed, and then is lit when the ownership of the media tray has been transferred to the blade workstation. It can take approximately 20 seconds for the operating system in the blade workstation to recognize the media tray. If there is no response when you press the media-tray select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade workstation. The operating system in the blade workstation must provide USB support for the blade workstation to recognize and use the removable-media drives and USB ports. The BladeCenter unit uses USB for internal communication with these devices. Activity LED: When this green LED is lit, it indicates that there is activity on the hard disk drive, flash drive, or network. Location LED: The system administrator can remotely light this blue LED to aid in visually locating the blade workstation. When this LED is lit, the location LED on the BladeCenter unit is lit also. The location LED can be turned off through the management-module Web interface or through IBM Director Console. Information LED: When this amber LED is lit, it indicates that information about a system error for the blade workstation has been placed in the system-error log. The information LED can be turned off through the management-module Web interface or through IBM Director Console. Blade-error LED: When this amber LED is lit, it indicates that a system error has occurred in the blade workstation. The blade-error LED turns off only after the error is corrected. Power-control button: This button is behind the control panel door. Press this button to turn on or turn off the blade workstation. Note: The power-control button has effect only if local power control is enabled for the blade workstation. Local power control is enabled and disabled through the management-module Web interface. Power-on LED: This green LED indicates the power status of the blade workstation in the following manner: v Flashing rapidly: The service processor (BMC) on the blade workstation is handshaking with the management module. v Flashing slowly: The blade workstation has power but is not turned on. v Lit continuously: The blade workstation has power and is turned on. Sleep-mode LED: When this green LED is lit, it indicates that the blade workstation is in Sleep mode. The blade workstation can be put in the Sleep or Hibernate mode by the operating system or by the thin client. The blade workstation can be awakened through the management-module Web interface, through IBM Director Console, or by the thin client. Chapter 2. Power, controls, jumpers, switches, and indicators 13
