POST Keys

The POST keys, if pressed after the keyboard POST indicator displays and before the last (speaker)
POST indicator displays, cause the system to start services or to initiate service mode boots used for
configuring the system and diagnosing problems. The keys are described below:
Note: The program function keys (F1-F12) on a keyboard attached to the HMC or USB card are not used
and will be ignored. After the keyboard POST indicator displays, you must use the numeric number
keys to enter input.
1 Key
The numeric 1 key, when pressed during POST, starts the System Management Services (SMS) interface.
5 Key
The numeric 5 key, when pressed during POST, initiates a system boot in service mode using the default
service mode boot list.
6 Key
The numeric 6 key works like the numeric 5 key, except that the firmware uses the customized service
mode bootlist.
8 Key
This option is used by service personnel. To enter the open firmware command line, press the numeric 8
key after the word keyboard displays and before the last word speaker displays during startup. After you
press the 8 key, the remaining POST indicators display until initialization completes.
When initialization and POST are complete, the open firmware command line (an OK prompt) displays.
Note: This option should only be used by service personnel to obtain additional debug information.
To exit from the open firmware command prompt, type reset-all or power off the system and reboot.
