firmware will use this terminal as the console, regardless of the previous console selection.
the
After a console has been selected, the console-selection sequence is only started at boot time if there is a
change in the system configuration (as previously described), or the contents of the system’s nonvolatile
memory (NVRAM) are lost.
Note: Moving an ASCII terminal from one serial port to another (from S1 to S2) cannot be detected by the
firmware, so it does not constitute a configuration change.
You can also initiate a system console-selection sequence from the SMS menus.
Power-On Self-Test
After power is turned on and before the operating system is loaded, the system does a power-on self-test
(POST). This test performs checks to ensure that the hardware is functioning correctly before the
operating system is loaded. During the POST, a POST screen displays, and POST indicators appear on
the firmware console (if one is connected). The next section describes the POST indicators and functions
that can be accessed during the POST.
Chapter 1. Reference Information 5
POST Indicators
POST indicators indicate tests that are being performed as the system is preparing to load the operating
system. The POST indicators are words that display on the system console. Each time that the system
starts a different step in the POST, a POST indicator word appears on the console. Each word is an
indicator of the tests that are being performed.
The POST screen displays the following words:
Memory Memory test
Keyboard Initialize the keyboard and mouse. The time period for pressing a key to access the
System Management Services, or to initiate a service mode boot is now open. See “POST
Keys” for more information.
Network Self-test on network adapters
SCSI Adapters are being initialized
Speaker Sounds an audible tone at the end of POST
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 system unit 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 AIX diagnostics from CD-ROM.
The default boot sequence is:
1. Diskette (if installed)
2. DVD-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 or the service processor menus.

PCI-X Slot Locations
Six PCI-X slots are available. Slots 1, 4, 5, and 6 are 64-bit capable at 133 MHz, 3.3 volts. Slots 2 and 3
are 32-bit capable at 66 MHz, 3.3 volts. All slots have hot-swap capabilities. The slots are numbered on
the rear of the chassis from left to right, 1 through 6.
All PCI-X slots are capable of running either 64-bit or 32-bit adapters. However, a 32-bit adapter operates
in a 32-bit mode and shows no performance advantage while running in a 64-bit slot. The following
illustration shows the PCI adapter slot locations when viewing from the rear of the system.
