* SSH / Ping to the CMM is working as expected.

* Executing '*standby_cmm -a "clia board"* ',the following is received:

  ```
  
  Pigeon Point Shelf Manager Command Line Interpreter
  No boards in the system
  ```

* No output on the console port of the SGM, SOL cannot connect to the SGM console.
* asg_version verify -v returns a hardware mismatch for the SGM component:

  ```
  
  BIOS version: database and hardware do not match: database - 2.28, hardware - N/A
  BL version: database and hardware do not match: database - 1.00, hardware - N/A
  IPMC version: database and hardware do not match: database - 1.02, hardware - N/A
  FPGA version: database and hardware do not match: database - 2.34, hardware - N/A
  NVRAM version: database and hardware do not match: database - 6.00, hardware - N/A
  ```

## Cause
