Pane 3 describes how to attach an additional ground cable to the rack chassis.
An additional chassis earth ground cable (not supplied) enables electrical current leakage to dissipate more efficiently.
Steps:
Ensure that the ground cable makes metal-to-metal contact with the attachment point. Remove paint or coating if necessary.
Attach the ground cable to one of the attachment points at the bottom rear of the system frame.
An image shows the location of the cable attachment points in the rack. A detail bubble provides a close-up view of an attachment point.
