Check the internal cables for damage. 9. Check for dirt, water, and any other contamination within the system unit. 10.Check the voltage label on the back of the system unit to ensure that it matches the voltage at the outlet.
Page 31: Chapter 2. Using System Guard
Chapter 2. Using System Guard This chapter introduces the SystemGuard service processor which is included in all Symmetric Multiprocessor models. Introduction SMP servers include a service processor, called SystemGuard, as a standard feature. SystemGuard continually monitors the hardware as well as the operating system. If, for instance, a CPU fails, the system detects this, reboots itself automatically and runs the built-in diagnostics on the hardware.
Page 32: Systemguard Power
SystemGuard Power SystemGuard has its own DC power boundary. This means that even if the system power is off (power button of the system in the off position), SystemGuard is still powered on, as long as the unit is still plugged into a power outlet. This allows control of the system even though the system is down.
Page 33: The Operator Panel
Reset Button Operator Panel Display Note: In the 7012 G Series the system board contains the NVRAM, the NVRAM battery, and the TOD. You can drain NVRAM by disconnecting the NVRAM battery. When NVRAM is drained it results in a reset of the TOD to 1969 which affects applications.
Page 34: Systemguard Consoles
SystemGuard Consoles SystemGuard works with two types of consoles: The Bump Console , which is an ASCII terminal attached to the S1 serial port. This console provides the normal input to the BUMP. It can be local or remote. The line speed for the BUMP console must be set to 9600 baud for either type of connection.
Page 35: Init Phase
Init Phase Init phase is entered when the power button on the Operator Panel is pressed on or when the power-on command is entered on the BUMP Console or Service Console. If the System Key is in Normal mode, the BUMP runs the built-in or resident power-on (PON)-tests on the system hardware, IPLs on the first available processor, runs the functional power on self-tests (POST) on the I/O subsystem to check the system, and finally loads the AIX operating system.
Page 36 Phase Change (Stand-By to Init Stage) The phase change from Stand-By to Init is called crossing the power boundary. This is achieved by pushing the power button on the Operator Panel or by typing the keyword power at the Stand-By prompt (>). Note that if you type power while the power button is not pushed in, nothing happens until you press the power button.
Page 37 Power-on (PON) Tests PON tests are run by SystemGuard whenever the system power comes on. There are two types of tests: A comprehensive set of tests are performed on the processors, cache, memory and related hardware when the Fast-IPL flag is disabled. A minimum core set of tests are performed on the processors, cache, memory and related hardware during fast-IPL which cannot be turned off.
Page 38 Enabling at least one processor from the STAND-BY MENU There are other resident PON tests to check other system resources. These tests are a subset of the SystemGuard maintenance offline tests, and reside within the flash EEPROM. These tests are divided into the following groups: BUMP Quick I/O Test Group These tests check the accessibility and the functions of the standard and direct I/O components from the BUMP: Async lines...
Page 39: Systemguard Parameters And Flags
Phase Change (Init to Boot) The maintenance phase is entered from the Init phase if the system key is in service mode. If the BUMP console present flag is set, the MAINTENANCE MENU is displayed on the BUMP console, and the system waits for an operator action. The maintenance menu choices are described on page 2-21.
Page 40: Working With Systemguard
Working with SystemGuard You can change SystemGuard parameters and flags from different locations They can be changed from the SystemGuard STAND-BY MENU, the SystemGuard MAINTENANCE MENU, the Diagnostics interface, and also from AIX. When the key signal is received, SystemGuard clears the screen and displays the SystemGuard prompt.
Page 41: Systemguard Menus
When the system is in Stand-By mode and the System Key (Physical or Electronic Key) is in Service mode, the STAND-BY MENU can be accessed and SystemGuard executed. If you turn the system unit power on from Stand-By mode with the System Key in the Normal position, the system boots to AIX Multi-User.
Page 42: Stand-By Menu
Stand-By Menu The STAND-BY MENU can only be entered when the system is in Stand-By mode (the word Stand-By must be displayed on the LCD display). Perform the following steps to bring up the STAND-BY MENU. 1. With Stand-By displayed on the LCD display press the Enter key on the BUMP console. The Stand-By prompt is the greater than (>) sign.

Page 254: Appendix E. System Power States
Appendix E. System Power States The state of the system is dependant on the condition of four variable conditions that effect how the system IPLs or shuts down. The four conditions are: the position of the Power-on button This button has two positions. It can be pressed in to the On position (position for turning the power on), or it can be in the out or Off position.
Page 255 If the command sbb is entered on the BUMP console, and the system key is in the Normal position, the system goes to the SBB_ECMD state. If the Power-on button is pressed and changes from the On position to the Off position, the system sets the was_shutdown status to false.
Page 256 If the power_fault status is false, the system attempts to power on. If the system then detects a power fault, the power_fault status is set to true. The system displays an operator panel LCD error message, and the system goes to the MAIN_STANDBY status. If no power fault is detected, the system goes to the IPL state.
Page 257 If the system power does not turn on, the Power-on button may be in the off position. Go to the system unit and press the Power-on button (only press the button once), If the system power still does not turn on there may be an earlier fault condition. Remove main power from the system unit, wait 30 seconds, and restore main power.
