Power Switch and Indicator LEDs

The power switch and light-emitting diodes (LEDs) on the front of your server allow you control power to the server, observe system power status, and observe disk activity.

These features also have other built-in capabilities to assist you in diagnosing system problems and observing system status:

 As soon as the system unit is connected to a power source, the power LED will

begin blinking slowly (about 2 flashes per second) to indicate that Standby Power is on, even though the system unit is not powered on or running.

 When the system unit is turned on by pressing the power switch, the power LED

lights steadily.

If the operating system is loaded and running, a memory dump of system information can be requested.

 To enable this function, the sysdumpdev -K command must be executed before

an error condition exists.

 To request a memory dump, press and hold the power switch for longer than two

seconds. Requesting a memory dump directs the operating system to save system information to a predefined file before turning off the system. This feature can be used to assist in recovery from system problems.

1-8 Service Guide

 When a memory dump has been requested the power LED will blink quickly

(about 10 flashes per second) to indicate that the dump has been started. This blinking will cease after about a minute whether or not the dump is complete, and the LED will return to its steady, lit state until the system turns off or reboots when the dump is complete.

 The memory dump file can be viewed by entering the the operating system

command:

sysdumpdev -L

The disk drive LED lights whenever the hard disk drives within the server are being used.

The disk drive LED also provides basic system diagnostic information:

 If no memory can be found as the system boots, the disk drive LED lights and

the system stops the boot process.

 If an error is detected in the firmware boot program, this LED lights and the

system stops, and the diskette activity LED begins blinking. This condition indicates that the system is requesting a Firmware Recovery Diskette, which should be made to facilitate resolution of system problems. For instructions on creating a Firmware Recovery Diskette, see Chapter 5, “System Management Services” on page 5-1.

Chapter 1. Reference Information 1-9

MAP 1540: Minimum Configuration

Notes:

1. This MAP assumes that a CD-ROM drive is installed and connected to the integrated SCSI adapter, and a Diagnostics CD-ROM disc is available.

2. If a power-on password or privileged-access password is installed, you will be prompted to enter the password before the diagnostic CD-ROM will load.

3. The term "POST indicators" refer to the ICONs (graphic display) or device mnemonics (ASCII terminal) that display while the POST is executing.

Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For this procedure, diagnostics are run on a minimally-configured system. If a failure is detected on the minimally-configured system, the remaining FRUs are exchanged one at a time until the failing FRU is identified. If a failure is not detected, FRUs are added back until the failure occurs. The failure is then isolated to the failing FRU.

The MAP steps on the following pages instruct you to reduce the system to one or more of the following configurations:

 System board, CPU card, 1 memory module.

If no failure is detected, the green power LED will be on and the system will beep twice (one short beep, followed by one long beep up to a minute or more later). Any other response means one of the remaining FRUs is failing.

 System board, CPU card, all memory modules and a terminal attached to the S1

port or a keyboard, display, and graphics adapter. If no failure is detected, The power LED will be on and the system will beep

twice (one short, followed by one long beep up to a minute or more later). The SMS screen will be displayed.

 System board, CPU card, all memory modules, CD-ROM drive, and a terminal

attached to the S1 port or a keyboard, display, and graphics adapter. If no failure is detected, The power LED will be on and the system will beep

Chapter 4. Loading the System Diagnostics

The system unit can be booted either from the default boot list or from the custom boot list. (See Chapter 5, “System Management Services” on page 5-1 for instructions on defining the custom boot list.)

To load Standalone diagnostics from the default boot list, perform the following procedure:

1. Verify with the system administrator and users that all programs may be stopped, then do so.

2. Turn off the system.

3. Wait 30 seconds, and turn on the system.

4. Immediately insert the diagnostic CD-ROM into the CD-ROM drive.

5. When or after the diskette indicator appears during startup, press the F5 key on a directly-attached keyboard (or the number 5 key on an ASCII terminal).

6. Enter any requested passwords.

Online diagnostics can be loaded by booting from the custom boot list by pressing the F6 key (on a directly-attached keyboard) or the number 6 key on an ASCII terminal.

The procedure for booting from the devices listed in the custom boot list (Online diagnostics) is the following:

1. Verify with the system administrator and users that all programs may be stopped, then do so.

2. Turn off the system.

3. Wait 30 seconds, and turn on the system.

4. When or after the diskette indicator appears during startup, press the F6 key on a directly-attached keyboard (or the number 6 key on an ASCII terminal).

5. Enter any requested passwords.

After any requested passwords have been entered, the system will attempt to boot from the first device of each type found on the list. If no bootable image is found on the first device of each type on the list, the system does not search through the other devices of that type for a bootable image; instead, it will poll the first device of the next type.

Chapter 4. Loading the System Diagnostics 4-1

If all types of devices in the boot list have been polled without finding a bootable image, the system will will restart, this gives the user the opportunity to start the System Management Services ( by pressing the F1 key on a directly attached keyboard or the number 1 on an ASCII terminal) before the system attempts to boot again.

Custom Boot List and Default Boot List

The default boot list is:

1. Diskette

2. CD-ROM

3. Hard File

4. Network  Token-Ring  Ethernet

Pressing the F5 key on a directly-attached keyboard (or the number 5 key on an ASCII terminal) causes the system to boot in service mode from this list.

Pressing the F6 key on a directly-attached keyboard (or number 6 key on an ASCII terminal) selects a service mode boot from the custom boot list, which is the boot list defined using the System Management Services described in Chapter 5, “System Management Services” on page 5-1. Like the default boot list, the custom boot list can contain four entries. The F6 or 6 keys work like the F5 or 5 keys, with the following exceptions:

 The system will search for a boot record according to the custom boot list.  If the custom boot list is discovered by a cyclical redundancy check to be

corrupted, the system will rebuild the custom boot list according to the default boot list. (The default boot list contains four entries, and for each matching device type found in the system unit, the system makes an entry in the custom boot list.)

 If no custom boot list is present, the system enters "none" in the corresponding

location within the custom boot list.

4-2 Service Guide

Chapter 5. System Management Services

These programs make it possible for you to view information about your system, run memory tests, and set the storage device from which the server boots.

If you have a graphical display connected to a display adapter in your system unit, then you can use the graphical System Management Services. Otherwise, you must use the text-based version of the System Management Services.

The graphical System Management Services is described in “Graphical System Management Services” on page 5-2; the text-based System Management Services is described beginning in “Text-Based System Management Services Programs” on page 5-11; the ASCII terminal is described beginning in “ASCII Terminal System Management Services Programs” on page 5-16.

To start the programs:

1. Turn on or shutdown and restart the system.

2. When the first screen appears, press the F1 key to use the graphical System Management Services. To use the text-based System Management Services, press the F4 key or number 4 key on an ASCII terminal.

Note: You must press F1 or F4 key after the diskette indicator appears on the

screen, but before the last indicator appears. After you have pressed the F1 or F4 key, the initialization indicators continue to display, and the System Management Services screen displays after the last indicator.

Note: It is recommended that you create a Firmware Recovery Diskette using the

Update Firmware selection in the System Management Services Tools section described in this chapter.

Chapter 5. System Management Services 5-1

Graphical System Management Services

When the graphical System Management Services program begins, the following screen appears.

The System Management Services screen contains the following objects.

Start Up: This function allows you to define a custom boot list, which defines the sequence in which devices are searched by the operating system for a bootable image.

Test: Allows you to repeatedly test the memory in your system.

5-2 Service Guide

Tools: Enables you to set and remove passwords and to set the unattended start mode. In addition, you can view information about your system and update system programs.

Exit: Returns you to the previous screen.

To select an object, use the arrow keys to highlight an object and then press Enter or the Spacebar. To leave the current screen, either press the Esc or select the Exit object.

This selection enables you to define a custom boot list or reset default list, which determines the order in which devices are searched by the firmware for a bootable image. The screen may show the following objects.

Diskette: Diskette drive.

CD-ROM: CD-ROM drive.

HDD: Hard disk drive.

5-4 Service Guide

Highlight the device which the system will search for first when booting, and press the Spacebar. Notice that numbers appear over the objects, indicating the order of the startup sequence. Up to four devices can be specified. To cancel your selection, select the Cancel object. The Default object sets the sequence to:

 Diskette drive  CD-ROM drive

 Hard disk drive

 Tape drive

 Network (if installed)

If your system has more devices than shown in the list, their objects will be displayed after those in the default sequence.

Attention: If you change your custom boot list, you must be extremely careful when doing

write

operations (for example, saving or formatting). You can accidentally

overwrite data or programs if you select the wrong drive.

Test

Selecting this object enables you to test the memory in your system unit.

Chapter 5. System Management Services 5-5

5-6 Service Guide

Tools

Selecting this object enables you to perform various tasks and view additional information about your system. The following screen appears with objects presented for your selection.

The following describes the objects on this screen.

Chapter 5. System Management Services 5-7

Power-On Password: Setting a power-on password helps protect information stored in your system. When you select this object, a screen with 8 empty boxes appears. Type your password in these boxes. You can use any combination of up to eight characters (A–Z, a–z, and 0–9) for your password. As you type a character, a key appears in the box. Press Enter when you are finished; you will be required to type the password again for verification. If you make a mistake, select the Cancel object and start again.

If you already had set a power-on password and wanted to remove it, select the following object.

Note: If you

forget

your password, you will have to remove the battery for at least 30 seconds to disable the password. See “Battery” on page 7-25.

A password can be set only after system power has been turned off and then on again. You cannot set a password after using the Ctrl+Alt+Del combination (or

warm boot

) to restart

the system.

Privileged-Access Password: The privileged-access password protects against the unauthorized starting of the system programs. Follow the same procedure described for the power-on password.

As with the power-on password, you must turn system power off and then on again before setting a privileged-access password.

5-8 Service Guide

Remote Mode: The remote mode, when enabled, allows the system to start from the defined boot device. This mode is ideal for network servers and other systems that operate unattended. You

must

set a power-on password before you can enable the remote mode. When the remote mode is set, the object changes to Remote On.

If you remove the power-on password, the remote mode is automatically reset, and the object returns to Remote Off.

Selecting Remote On resets the startup mode to the normal startup sequence.

Firmware: Enables you to update system firmware. Firmware should be selected only when a change to the

system firmware is needed. A

Firmware Update
