Chapter 2 Preparing for Installation
Safety Recommendations
Note If you need to remove the chassis cover to install a hardware component, such as additional memory or an interface card, doing so does not affect your Cisco warranty. Upgrading the ASA does not require any special tools and does not create any radio frequency leaks.
Observe the following safety guidelines:
•Keep the chassis area clear and
•Keep tools away from walk areas in which you and others might fall over them.
•Do not wear loose clothing or jewelry, such as earrings, bracelets, or chains that could get caught in the chassis.
•Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Never attempt to lift an object that is too heavy for one person to handle.

Maintaining Safety with Electricity
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12
Follow these guidelines when working on equipment powered by electricity:
•Before beginning procedures that require access to the interior of the chassis, locate the emergency
•Do not work alone if potentially hazardous conditions exist anywhere in your work space.
•Never assume that power is disconnected from a circuit; always check the circuit.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
•If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Disconnect power from the system.
–If possible, send another person to get medical aid. Otherwise, assess the condition of the victim, and then call for help.
–Determine whether or not the person needs rescue breathing or external cardiac compressions; then take appropriate action.
•Use the ASA chassis within its marked electrical ratings and product usage instructions.
•Install the ASA in compliance with local and national electrical codes as listed in the REgulatory Compliance and Safety Information document.
