4.3.3 Attaching a Ground Cable (Optional)

The Oracle Exadata Rack power distribution units (PDUs) achieve earth ground
through their power cords. Final chassis ground is achieved by way of the ground
prong when you connect the power cord to a socket. For additional grounding, attach a
chassis earth ground cable to Oracle Exadata Rack. The additional ground point
enables electrical current leakage to dissipate more efficiently.
Ensure the installation site has properly grounded the power source in the data
1.
center. The facility PDU must have earth ground.
Ensure all grounding points, such as raised floors and power receptacles,

reference the facility ground.
Securing Oracle Exadata Rack Using the Leveling Feet
WARNING:
The PDU power input lead cords and the ground cable must reference a
common earth ground. If they do not, then a difference in ground potential can
be introduced. If you are unsure of your facility's PDU receptacle grounding,
then do not install a ground cable until you confirm that there is a proper PDU
receptacle grounding. If a difference in ground potential is apparent, then you
must take corrective action.
Note:
A grounding cable is not shipped with the system.
