Power-on LED: This green LED indicates the power status of the blade server in the following manner:

vFlashing rapidly - The service processor on the blade server is handshaking with the BladeCenter management module.

vFlashing slowly - The blade server has power but is not turned on.

vLit continuously - The blade server has power and is turned on.

If there is no response when you press the keyboard/mouse/video select button, you can use the management-module Web interface to see whether local control has been disabled on the blade server.

You can also press keyboard keys in the following sequence to switch keyboard/mouse/video control between blade servers:

NumLock 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. A blade server that occupies more than one blade bay is identified by the lowest bay number that it occupies.

If you install the Microsoft® Windows® 2000 operating system on the blade server while it is not the current owner of the keyboard, video, and mouse, a delay of up to 1 minute occurs the first time you switch the keyboard, video, and mouse 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 keyboard-video-mouse switching time frame (up to 20 seconds).

Information LED: When this LED is lit, it indicates that a noncritical event has occurred. A light path diagnostics LED on the processor board or I/O board is also lit to help isolate the error. The information LED can be turned off through the BladeCenter management-module Web interface or through the 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.
