Installation Grounding
The 770 W AC power supplies have internal grounding and so no additional grounding is required when
the supported AC power cords are used.
When using the 1050 W DC power supply, additional grounding of the server chassis to the earth ground
of the rack is available. A single screw hole for use with your grounding lug and grounding wire is
supplied on the chassis rear panel.
You must provide your own screw with lock-washer, grounding lug, and grounding wire. The
Note
recommended lug is Panduit LCD10-14AF-L or equivalent. The grounding point on the chassis is sized
for a single #10-32 screw. A lock-washer is required to secure the lug to the chassis. The grounding lug
must fit a #10-32 screw and 14 AWG wire. The grounding cable that you provide must be 14 AWG
(2 mm), minimum 60° C wire, or as permitted by the local code.
