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

Miscommunication between the CMM and the SGMs IPMI controller.
