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.

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 |
