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 server. Notes: 1. The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard and mouse, even if the keyboard and mouse have PS/2-style connectors. 2. If you install a supported Microsoft Windows operating system on the blade server while it is not the current owner of the KVM, a delay of up to 1 minute occurs the first time that you switch the KVM to the blade server. During this one-time-only delay, the blade server device manager enumerates the keyboard, video, and mouse and loads the device drivers. All subsequent switching takes place in the normal KVM switching time frame (up to 20 seconds). 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 server. 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 server. It can take approximately 20 seconds for the operating system in the blade server 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 server. Note: The operating system in the blade server must provide USB support for the blade server to recognize and use the removable-media drives and front-panel USB ports. Activity LED: When this green LED is lit, it indicates that there is activity on the hard disk drive or network. Location LED: When this blue LED is lit, it has been turned on by the system administrator to aid in visually locating the blade server. 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 server has been placed in the management-module event 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 server. The blade-error LED will turn off only after the error is corrected. Power-on LED: This green LED indicates the power status of the blade server in the following manner: v Flashing rapidly: The service processor (BMC) on the blade server is communicating with the management module. v Flashing slowly: The blade server has power but is not turned on. v Lit continuously: The blade server has power and is turned on.
