Lifting and weight-related precautions DANGER This device might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before servicing. DANGER Remove both power cords before servicing. DANGER Disconnect the power cord from all power sources to completely remove power from the device. DANGER To avoid high voltage shock, do not open the device while the power is on. DANGER Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions. CAUTION Use a separate branch circuit for each power cord, which provides redundancy in case one of the circuits fails. CAUTION Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the input power connectors. CAUTION The power supply switch must be in the off position when you insert the power supply into the chassis. Damage to the switch can result if a live power supply is installed. CAUTION Carefully follow the mechanical guides on each side of the power supply slot and make sure the power supply is properly inserted in the guides. Never insert the power supply upside down. Lifting and weight-related precautions DANGER Use safe lifting practices when moving the product. DANGER Mount the devices you install in a rack as low as possible. Place the heaviest device at the bottom and progressively place lighter devices above. Brocade G620 Hardware Installation Guide 19 53-1003990-01
