Family

■Look carefully for possible hazards in your work area, such as ungrounded power extension cables, missing safety grounds, and moist floors.

■Locate the emergency power-off switch in the room before installation. Shut the power off at once in case accident occurs.

■Unplug all the power cords and external cables before moving the chassis.

■Do not maintain the equipment alone when it has been powered.

■Never assume but check each time that power has been disconnected from a circuit.

■Do not place the switch on a moist area and avoid liquid flowing into the switch.

The Switch 8800 Family are rather big and heavy, so follow the recommendations below when moving it.

■Remove all the external cables (including power cords) before moving the chassis.

■Do not move the switch alone. Work with another person.

■Move the switch slowly and stably. Never move suddenly or twist your body.

■Move the switch at stable and consistent paces with your peer. Keep balance of your body.

c CAUTION: You can only hold the handles at both sides of the chassis when moving the switch, but not the plastic panel of the chassis, the handle of the fan frame, the handle of the PSUs or the air vents of chassis.

As these parts are not designed for bearing the weight of the entire chassis, any attempt trying to carry the switch with these parts may impair the switch and even injure yourself.
