Install a Ground Cable (Optional)
The SPARC SuperCluster T4-4 power distribution units (PDUs) achieve earth ground through their power cords. For additional grounding, attach a chassis earth ground cable to the SPARC SuperCluster T4-4. The additional ground point enables electrical current leakage to dissipate more efficiently.
 | Caution - Do not install a ground cable until you confirm that there is proper PDU receptacle grounding. The PDU power input lead cords and the ground cable must reference a common earth ground. |
Note - A grounding cable is not shipped with the system.
-
Ensure that the installation site has properly grounded the power source
in the data center.
An earth ground is required. See Grounding Requirements
- Ensure that all grounding points, such as raised floors and power receptacles, reference the facilities ground.
-
Ensure that direct, metal-to-metal contact is made for this installation.
The ground cable attachment area might have a painted or coated surface that must be removed to ensure solid contact.
-
Attach the ground cable to one of the attachment points located at the
bottom rear of the system frame.
The attachment point is an adjustable bolt that is inside the rear of the rack on the right side.
