Both the metal rack and the equipment must be grounded to ensure electrical safety and prevent electrical noise. Grounding the metal rack provides a common ground reference for all the equipment in the rack, which can reduce the risk of ground loops and interference. Grounding the individual pieces of equipment helps to protect against electric shocks and ensures that any fault current will be safely directed to ground.
