POST Keys

The POST keys, if pressed after the keyboard POST indicator displays and before the last POST indicator
speaker 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 CEC drawer are not used and
will be ignored. After the keyboard POST indicator displays, you must use the numeric number
keys.
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.
This mode attempts to boot from the first device of each type found in the list. It does not search for other
bootable devices of that type if the first device is not bootable. Instead, it continues to the next device type
in the list. The firmware supports up to five entries in the boot list.
Note: This is the preferred method of loading standalone diagnostics from CD-ROM.
The default boot sequence is:
1. Diskette (if installed)
2. CD-ROM (if installed)
3. Hard file
4. Tape drive (if installed)
5. Network
a. Token ring
b. Ethernet
6 Key
The numeric 6 key works like the numeric 5 key, except that firmware uses the customized service mode
bootlist that was set up in the AIX service aids.
Note: This is the preferred method of loading online diagnostics from the boot hard disk.
