Built-In-Self-Test (BIST)
The service processor initiates a Built-In-Self-Test (BIST) on the Central
Electronics Complex (CEC) chips when the power button is pressed. The
VPD is read, the CRC is done, and the processor compatibility test is run.
LED Code range is E0A0 - E0E1.

The system firmware displays the device name or device icon being tested.
After the keyboard name or icon appears, you can enter the Systems
Management Services menu by hitting the 1 key (if using a ASCII terminal) or
the F1 key (if using a Graphics terminal).
