Normal control panel functions

Following are instructions to use function 01 through 49. Functions 21 through 49 are available when you select manual mode.

The instructions you follow for function 01 or function 02 depends on whether your server uses a keystick. Also, the instructions for function 01 and 02 alternate between servers with a keystick and servers without a keystick.

To determine how to activate functions 01 and 02 on a control panel, do the following:

Does the control panel have an electronic keylock (a keystick)?

Yes	Go to the next step.
No	The system displays the IPL key mode (M or N only). The IPL key modes, Auto and Secure, are not supported. Follow function 01 and 02 procedures for system without a keystick.

Insert the keystick.
Press the Mode-selection button to select the IPL mode. Follow function 01 and 02 procedures for systems with a keystick.

Note: The function that is displayed is not activated until you press Enter on the control panel.

To select a function number, press the Increment (^) or Decrement (V) button on the control panel. To activate the function, press Enter on the control panel while the system displays the required function number.

Function 03-Start IPL

The system enables function 03 only when the key mode is in manual and the system power is on.

This function starts an IPL of the selected IPL type when you press the Enter button. The system will load all the Licensed Internal Code.

Attention: The system does not perform a system shutdown before the IPL. The use of this function can cause loss of data.

Function 04-Lamp Test

This function shows whether any control panel indicators are burned out and whether characters that are displayed on the control panel Function/Data display are valid. When you activate this test, all the control panel lights and indicators flash on and off.

The lamp test continues on the system control panel until you perform another control panel function or a power procedure. The lamp test for the expansion unit control panel is active for 25 seconds and does not flash.

Use this procedure to verify that the lights on the system control panel are working correctly. If you cannot complete these steps, contact your service provider.

Power on the system.
Press the Increment (^) or Decrement (V) buttons on the control panel to display Function 04.
Press Enter on the control panel.

Do all of the lights and indicators on the system control panel flash on and off?

Yes	Proceed to the next step.
No	Need to exchange the control panel or the replaceable unit that contains the control panel function (system unit backplane (MB1) or tower card (CB1)). Contact your service provider.

Do all the control panel lights on the expansion unit come on?
Yes End.

No Exchange the control panel on the expansion unit.

The lights on the system control panel are working correctly.

Function 05-SPCN SRC

Function 05 displays information about power faults and provides informational reference codes during disk-unit concurrent maintenance procedures. The format for this function is as follows:

SPCN SRC formats

This image shows the format for Function 05. In this format: RR= The frame number where the failing unit is installed; U = the SPCN port to which the failing unit is connected; rrr= Unit reference code (URC).

Function 07

Function 07 is only used during service by authorized IBM^® service representatives.

Function 08-Fast Power Off

Function 08 is enabled only when the key mode is in manual mode and the system power is on.

Use this function when the system is suspended and you cannot perform a power down.

The first time that you select function 08 and press Enter, the system displays an attention SRC, 11 A1xx 8008. This SRC indicates that you selected function 08. The second time that you select function 08 and press Enter, you confirm the request to power off. To perform a fast power off, see Stop the system in the Basic system operations topic.

Attention: No system shutdown is performed before the IPL. The use of this function can cause loss of data.

Attention: If the system password was changed at the most recent IPL, performing a fast power off might cause that new password information to be lost.

Functions 09 to 10-Reserved

These functions are reserved for future control panel operations.

Functions 11 to 19 - System Reference Code (SRC)

Functions 11 though 19, if enabled, represent the words of the SRC.

You must record SRC information for error reporting and contact your service provider.

Function 20-System Type, Model, Feature Code, Hardware Level, and IPL Path Description

This function displays the machine type, model, processor feature code, hardware level, and IPL path description in the following format:

t m m m c c c c _ _ _ _ _ _ _ _

h h h h _ _ _ _ i i i i i i i i

Values for t indicate the machine type:

1	9401
2	9402
4	9404
6	9406

Values for m indicate the model:

mmm	Model number (for example, 820)

Values for c indicate the system processor feature code:

cccc	Processor feature code (for example, 23A4)

Values for hhhh indicate the system processor hardware level:

hhhh	Processor hardware level (for example, 1025)

Values for iiiiiiii indicate the description of the system power on or restart path:

iiiiiiii

The restart path description (for example, 00000001 indicates that the system was powered on by using the white button on the control panel).

You should record this information with the SRC.

Function 21-Make DST Available

This function makes DST available on the system console display. The Use Dedicated Service Tools (DST) display appears on the primary or alternative console.

To exit DST and return to the operating system, select the Resume operating system display option on the Use Dedicated Service Tools (DST) display.

Function 22-Dump Main Storage

This function dumps main storage and processor data to the disk.

Note: Before to pressing function 22, determine whether function 34 is available ( 00 shows in the panel after you select function 34). If it is available, then the system is attempting to run a main storage dump IPL. Using function 34 attempts to try the IPL again, such that the original dump is not lost. If function 34 is not enabled, ( >FF shows in the panel after you select function 34), go back and start function 22.

The first time that you select function 22 and press Enter, the system displays attention SRC 11 A1xx 3022. This indicates that you selected function 22. To dump main storage and system processor data to the disk, you must select function 22 again and press Enter.

Use this function only when a main storage dump is necessary, for example, after a suspended (system hang) condition or after an operating system failure.

Attention: No system shutdown is performed before the main storage dump. The use of this function can cause loss of data.

Functions 25 and 26-Service Switches 1 and 2

In function 25, the service representative switch 1 is set. Function 25 is the first step necessary to set the service function range (50 to 99).

In function 26, the service representative switch 2 is set. Function 26 is the second step necessary to set the service function range (50 to 99).

Function 33-Reorder SPCN Addressing

This function puts the rack addresses in the correct order to show their position in the system power control network (SPCN). Use it when you have added racks to or removed them from the system.

Function 34-Retry MSD IPL

Function 34 is enabled only for main storage dump IPLs. You can use it when the system is hung during the (MSD) IPL to try the IPL again without losing the original dump information.
