Default CMM uBoot Tests

Startup diagnostics on the Chassis Monitoring Module (CMM) use the uBoot diagnostic utility. The following uBoot tests are executed whenever the CMM is powered on or reset. If any of these tests fail, the CMM will not start. See About Diagnostics Failures for additional information.

uBoot Test

Purpose

MPC8245 BIST

Read/verify local BIST register

Testing Register PLD

Verify access to the PLD

Testing SPI PLD

Verify communications with the management switches

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 1MB of Memory)

Check for data integrity in the flash memory

Testing IMAX Initialization

Verify that IMAX can be initialized

Testing Local FourEyes Initialization

Verify that the local FourEyes can be initialized

Testing Blade # FourEyes Initialization

Verify that the FourEyes on the specified blade(s) can be initialized

Testing NEM # FourEyes Initialization

Verify that the FourEyes on the specified NEM(s) 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

INTEL MAC/PHY # TEST

Verify communications with the specified MAC/PHY(s)

Management Switch # BIST

Read/verify BIST register on the specified management switch(es)

MPC8245 to Management Switch # via Intel MAC/PHY Link Status

Verify link between specified management switch and CPU port

Checking environmental enetaddr not at default value

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