(Optional) Attach a Grounding Cable
The PDUs achieve earth ground through their power cords. For additional grounding, optionally attach a chassis earth ground cable to the rack. 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 facility AC receptacle grounding. The PDU power cords and the ground cable must reference a common earth ground. |
Note - A grounding cable is not shipped with the server.
-
Ensure that the installation site has properly grounded the power source
in the data center.
An earth ground is required. See Grounding Requirements. Consult with your facilities manager or a qualified electrician for the specific instructions at your data center.
- 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 on the rack
frame.
-
On a Sun Rack II 1242 rack, locate the attachment points at the
bottom rear of the rack frame.
-
On an Oracle Rack Cabinet 1242, locate the attachment point at the
bottom rear of the rack, inside the V-shaped support.
