Installation Grounding
The AC power supplies have internal grounding and so no additional grounding is required when the
supported AC power cords are used.
When using a DC power supply, additional grounding of the server chassis to the earth ground of the
rack is available. Screw holes for use with your grounding lugs and grounding wires are supplied on the
chassis rear panel.
Note
The grounding points on the chassis are sized for M5 screws. The grounding points are spaced at 0.625
inches (15.86 mm). You must provide your own screws, grounding lug, and grounding wire. The
grounding lug required is a Panduit LCD10-14AF-L or equivalent. The grounding cable that you provide
must be 14 AWG (2 mm), minimum 60° C wire, or as permitted by the local code.
See Figure 3-30 for the location of the grounding lug screw-holes on the chassis rear panel.
