Installing The Firewall In A Standard 19-Inch Rack - H3C F5030 Manual

As shown in Figure2-2, the firewall provides a primary grounding point at the rear panel and an
auxiliary grounding point at the left side. The primary grounding point has a grounding sign and a
grounding screw.
The grounding screw at the primary grounding point is also applicable to the auxiliary grounding
point. To use the auxiliary grounding point, attach the grounding cable to the grounding point before
you install the firewall in a rack.
The procedure is the same for connecting a grounding cable to the primary grounding point and the
auxiliary grounding point. This section uses the primary grounding point as an example.
To connect the grounding cable:
1. Remove the grounding screw from the primary grounding point at the device rear.
2. Attach the grounding screw to the ring terminal of the grounding cable.
3. Use a screwdriver to fasten the grounding screw into the grounding hole.
4. Connect the other end of the grounding cable to the grounding strip on the rack.
