or repairing the appliance. When you touch both a live power source or wire and ground, any metal objects can heat up

rapidly and may cause burns, set clothing on fire, or fuse the metal object to an exposed terminal.

Use a regulating, uninterruptible power supply (UPS) to protect the appliance from power surges and voltage spikes, and

to keep the appliance operating in case of power failure.

Never stack the appliance on top of any other server or electronic equipment.

All appliances are designed to be installed on power systems that use TN earthing. Do not install your device on a power

system that uses either TT or IT earthing.

Make sure that the appliance has a direct physical connection to the earth during normal use. When installing or repairing

an appliance, always make sure that the ground circuit is connected first and disconnected last.

Make sure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S. (240 VAC, 16 A international) is used on all

current-carrying conductors on the power system to which your appliances are connected.

Do not work alone when working with high voltage components.

Always disconnect the appliance from power before removing or installing any component. When disconnecting power,

first shut down the appliance, and then unplug the power cords of all the power supply units connected to the

appliance. As long as the power cord is plugged in, line voltages can be present in the power supply, even when the power

switch is OFF.

Do not use mats designed to decrease static electrical discharge as protection from electrical shock. Instead, use rubber

mats that have been specifically designed as electrical insulators.

Make sure that the power source can handle the appliance's maximum power consumption rating with no danger of an

overload. Always unplug any appliance before performing repairs or upgrades.

Do not overload the wiring in your server cabinet or on your server room rack.

During thunderstorms, or anticipated thunderstorms, avoid performing any hardware repairs or upgrades until the danger

of lightning has passed.

When you dispose of an old appliance or any components, follow any local and national laws on disposal of electronic

waste.

To prevent possible explosions, replace expired batteries with the same model or a manufacturer-recommended

substitute and follow the manufacturer’s instructions for battery replacement.

Never remove a power supply cover or any sealed part that has the following label:

Appliance Precautions

Determine the placement of each component in the rack before you install the rails.

Install the heaviest appliance first, at the bottom of the rack, and then work upward. Distribute the load on the rack

evenly. An unbalanced rack is hazardous.

Allow the power supply units and hard drives to cool before touching them.

Install the equipment near an electrical outlet for easy access.

Mount equipment in a rack with sufficient airflow for safe operation.

For a closed or multiple-unit rack assembly, the ambient operating temperature of the rack environment might be

greater than the ambient temperature of the room. Therefore, consider the lowest and highest operating

temperatures of the equipment when making a decision about where to install the appliance in the rack.
