performs a simple test on them. The system firmware displays the device 
name or device icon being tested. After the keyboard name or icon appears, 
you can enter the Systems Management Services menu by hitting the 1 key 
(on a ASCII terminal) or the F1 key (on a graphics terminal).

You can also enter one of the following:

  • 5 (on a ASCII terminal) or F5 (on a graphics terminal) to start the 

Stand-Alone Diagnostics (CD).

  • 6 (on a ASCII terminal) or F6 to start the On-line Diagnostics (Hard Disk)

Depending on the boot device, a checkpoint may be displayed on the 
operator panel for an extended period of time while the boot image is 
retrieved from the device. If a bootable image is found, then the system unit 
loads and starts the operating system.The AIX Boot code indicates LED 
progress codes in the range from 05XX to 09XX. After the AIX Boot is 
completed, the AIX login prompt appears on the main console.

If no bootable operating system image is found on any of the storage devices 
listed in the system firmware boot list, then the system unit attempts to boot 
again. With each attempt, you have the opportunity to start the System 
Management Services (SMS) as described in 6.7.1, “SMS Start-Up” on page 
173.

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

After the A/C power is turned on, the System Support Controller (SSC) 
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.
