Grounding Requirements
For TN power systems, always connect the PDU input power cords into grounded power outlets. For TT power systems, always attach a grounding cable to the rack frame. Refer to Attaching a Grounding Cable in Sun Rack II User’s Guide for further information.
 | Caution - To reduce the risk of electric shock or damage to installed equipment, never disable the grounding plug on any power cord or receptacle. |
