Cisco Wide Area Application Engine 511 and 611 Hardware Installation Guide

• 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.
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):
• 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.
Rack Installation Safety Guidelines
Before installing your device in a rack, review the following guidelines:
• 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.
