Typical Boot Sequence for Eserver pSeries 610 Model 6C1 and Model 6E1
After the ac power is turned on, the system support controller (SSC) startup begins, and
releases reset to the service processor. If the SSC cannot communicate with the
service processor, the LCD displays 4BA00000. If the service processor is not present,
the LCD displays 4BA00001.
A typical boot sequence is as follows:
1. Service processor self-test
v Service processor card performs self-test and NVRAM initialization.
v LCD code range is E000 - E07F.
v LCD code is OK when complete.
2. Service processor in standby mode
v You can enter the service processor menus whenever the LCD code is OK,
STBY, or has an eight-digit error code on the LCD display by pressing the Enter
key on an ASCII terminal connected to serial port 1.
3. Built-In Self-Test (BIST)
v The service processor initiates built-in self-test (BIST) on the central electronics
complex (CEC) when the power button is pressed.
v The VPD data are read and the CRC is checked.
v The processor compatibility test is run.
v LCD code range is E0A0 - E0E1.
4. System Initialization
v System firmware begins to execute and initializes system registers after LCD
code E0E1.
v LCD code range is E1XX - E2XX.
5. Memory Test
v The system firmware tests the system memory and identifies failing memory
DIMM locations.
v LCD code range is E3XX.
6. Device Configuration and Test
v System firmware checks to see which devices are in the system and performs a
simple test on them.
