Because of its integrated service processor, the boot sequence of the Model
260 is different than the Model 150.

start-up begins, and releases reset to the service processor. If the SSC
cannot communicate with the service processor, the LED displays a
4BA00000 code. If the service processor is not present, the LED displays
4BA00001.
