Connecting the ground cables to the rack grounding strip

To connect the power supply ground cables to the rack grounding strip:

1Locate the rack grounding strip at the back base of the rack (Figure 31).

Note: Figure 31 shows an example of a rack grounding strip. Your rack grounding strip can look different than the one shown in this example.

2Attach the lug ends of the power supply ground cables to the rack grounding strip (Figure 31).

Use a 7/16-inch hex wrench to fasten the hardware in the correct order.
