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 |
Ensure that MAC addresses are programmed and that none use the default value |
