The following illustrations show the LEDs and LED power switch on the processor board and I/O board. You need to remove the blade server from the BladeCenter unit, open the cover, and press one of the Light path diagnostics buttons to light any error LEDs that were lit during blade server operation. These LEDs will remain lit for a maximum of 25 seconds. See “Light path diagnostics” on page 86 for detailed information about this feature.
