Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the device. To prevent static damage, discharge

static electricity from your body before you touch any of your system's electronic components. You can

do so by touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

Rack Installation Safety Guidelines

Before installing your device in a rack, review the following guidelines:

•

OL-20929-01

Use only approved power cables. If you have not been provided with a power cable for your system

or for any AC-powered option intended for your system, purchase a power cable that is approved

for use in your country. The power cable must be rated for the product and for the voltage and

current marked on the product's electrical ratings label. The voltage and current rating of the cable

should be greater than the ratings marked on the product.

To help prevent electric shock, plug the system components and peripheral power cables into

properly grounded electrical outlets. These cables are equipped with three-prong plugs to help

ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.

Observe power strip ratings. Make sure that the total ampere rating of all products plugged into the

power strip does not exceed 80 percent of the power strip ampere ratings limit.

Do not use appliance or voltage converters or kits sold for appliances with your product.

To help protect your system components from sudden, transient increases and decreases in electrical

power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

Position cables and power cords carefully; route cables and the power cord and plug so that they

cannot be stepped on or tripped over. Be sure that nothing rests on your system components' cables

or power cord.

Do not modify power cables or plugs. Consult a licensed electrician or your power company for site

modifications. Always follow your local or national wiring rules.

When unpacking a static-sensitive component from its shipping carton, do not remove the

component from the antistatic packing material until you are ready to install the component in your

system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from

your body.

When transporting a sensitive component, first place it in an antistatic container or packaging.

Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and

workbench pads.

Two or more people are required to install the device in a rack.

Ensure that the room air temperature is below 95°F (35°C).

Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.

Plan the device installation starting from the bottom of the rack.

Install the heaviest device in the bottom of the rack.

Do not extend more than one device out of the rack at the same time.

Remove the rack doors and side panels to provide easier access during installation.
