Rack Mounting
When you prepare your equipment rack:
• Make sure that the rack is bolted to the floor and braced to a wall or ceiling.
• Make sure that the rack is permanently grounded to earth ground. The equipment rack must be grounded
to the same ground point used by the service in your area.
• The AC cord is the primary ground.
When you install the chassis, use a level to ensure the chassis is installed level.
