only. This cabling must be shielded.
General Safety Practices
Follow these guidelines to ensure general safety:
• Keep the chassis area clear and dust-free during and after installation.
• Keep tools away from walk areas where you or others could fall over them.
• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf, and roll up
your sleeves.
• Wear safety glasses when 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 equipment unsafe.
Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
Warning
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when connected
to power and ground and can cause serious burns or weld the metal object to the
terminals.
• Locate the emergency power-off switch in the room in which you are working. Then, if an electrical
accident occurs, you can quickly shut the power OFF.
• Disconnect all power before installing or removing a Cisco router chassis
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
–
Use caution; do not become a victim yourself.
–
Turn OFF power to the chassis.
–
If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim and then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
