CONSTELLATION ES.3 SAS PRODUCT MANUAL, REV. B 47
10.4 GROUNDING
Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which
the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired for the
system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive (electrically
isolating) method of mounting the drive in the host equipment.
Increased radiated emissions may result if you do not provide the maximum surface area ground connection between system ground and
drive ground. This is the system designer’s and integrator’s responsibility.
