Tests Run During Extended uBoot on the SP

When you run extended uBoot diagnostics on the SP, the following tests are performed.

Extended uBoot Test

Purpose

Memory Data Bus Test

Check for opens/shorts on the DIMMs' data bus

Memory Address Bus Test

Check for opens/shorts on the address bus for the entire memory space

Memory Data Integrity Test (Top 9MB of Memory)

Check for data integrity in the flash memory

Testing IMAX Initialization

Verify that IMAX can be initialized

EEPROM Data Bus Test

Check for opens/shorts on the EEPROM's data bus

Memory Data Integrity Test (Remaining Memory)

Check for data integrity in the remainder of system memory

Checking ECC

Verify that there is no more than one ECC error

ETHERNET PHY # Chip ID Test

Verify ability to read from the specified Ethernet PHY

USB Controller # Chip ID Test

Verify value of chip ID register

USB Controller # Read/Write Test

Verify ability to read and write from the specified USB controller

ETHERNET PHY # Internal Loopback Test

Send packets to Ethernet PHY and confirm data returned

ETHERNET PHY # to System Controller # Link Status

Verify link between the specified PHY and the specified CMM

Access to BIOS FLASH

Verify connectivity to BIOS flash memory

TEMPERATURE SENSOR Test

Verify integrity of temperature sensors

Testing Electronic Circuit Breakers

Verify that current and voltage to/from 48V regulators are within specification

Testing ADM1024s

Verify that ADM1024s are within specification

Checking environmental enetaddr not at default value
