Connect the Chassis Ground Wire
This procedure is optional for servers with AC input power. It is acceptable to ground the server through the supplies and chassis ground wire.
 | Caution - The server chassis must be grounded with the power supply ground pins or with the chassis ground holes. It is acceptable to have both grounds connected. |
-
Obtain a grounding lug (two-hole, long flared barrel, #6 AWG wire, ¼ inch stud
hole, 5/8 inch hole spacing, NEMA hole sizes and spacing, 45° angle tongue) and
two M5 screws.
The grounding lug and screws must be supplied by the customer. The grounding lug should be a two-hole, 1/4" stud hole, with 5/8" hole spacing.
-
Go to the rear of the server and locate the two grounding holes beneath fan
module 4 (FM4).
- Position and align the grounding lug on the two grounding holes at the rear of the chassis.
- Secure the grounding lug to the grounding holes using the two M5 screws.
-
Secure the other end of the grounding wire to the earth ground in the
building.
You can secure the grounding wire to a proper grounding point on the rack, as long as the rack is properly grounded to the earth ground in the building.
