Safety Recommendations
Use the following guidelines and the information in the following sections to help ensure your safety and
protect the PIX security appliance. The list of guidelines may not address all potentially hazardous
situations in your working environment, so be alert and exercise good judgement at all times.
Note If you need to open the PIX security appliance case to install a hardware component, such as additional
memory or an interface card, doing so does not affect your Cisco warranty. Upgrading the PIX security
appliance does not require any special tools and does not create any radio frequency leaks.
The safety guidelines are as follows:
• Keep the chassis area clear and dust-free before, during, and after installation.
• Keep tools away from walk areas where you and others could 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.
This section includes the following topics:

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.
Follow these guidelines when working on equipment powered by electricity:
• Before beginning procedures that require access to the interior of the PIX security appliance, locate
the emergency power-off switch for the room in which you are working. Then, if an electrical
accident occurs, you can act quickly to turn off the power.
• 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.
