Statement Safety Recommendations Before installing, configuring, or maintaining the router, review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco Series ISR s guide that comes with your router. Follow these guidelines to ensure general safety: Never attempt to lift an object that might be too heavy for you to lift by yourself.
Keep the chassis area clear and dust-free during and after installation. If you remove the chassis cover, place it in a safe place. Keep tools and chassis components away from walk areas.
Do not wear loose clothing that may get caught in the chassis. Fasten any tie or scarf and roll up sleeves. Wear safety glasses when working under conditions that might be hazardous to your eyes. Do not perform any action that may create a hazard to people or makes equipment unsafe.
Safety with Electricity Warning This unit might have more than one power supply connection. Statement Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement Warning Read the installation instructions before connecting the system to the power source. Statement Warning The covers are an integral part of the safety design of the product.
Statement Follow these guidelines when working on equipment powered by electricity: Locate the emergency power-off switch in the room in which you are working. If an electrical accident occurs, you can quickly turn off the power. Disconnect all power before doing the following: — Installing or removing a chassis — Working near power supplies Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
Do not work alone if hazardous conditions exist. Never assume that power is disconnected from a circuit. Always check. Never open the enclosure of the internal power supply. If an electrical accident occurs to another person, proceed as follows: — Use caution; do not become a victim yourself.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source but has telephone wiring or other network cabling connections: Never install telephone wiring during a lightning storm. Never install telephone jacks in wet locations unless the jack is specifically designed for it. Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface. Use caution when installing or modifying telephone lines.
Remove power cables from all installed power supplies before opening the chassis. Always follow these ESD prevention procedures when removing and replacing modules: Ensure that the router chassis is electrically connected to the ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching a metal part of the chassis. Caution For the safety of your equipment, periodically check the resistance value of the anti-static strap. It should be between 1 and 10 megohms Mohm. General Site Requirements This section describes the requirements your site must meet for the safe installation and operation of your router.
Keep your system components away from radiators and heat sources, and do not block cooling vents. Do not spill food or liquids on your system components, and never operate the product in a wet environment. Do not push any objects into the openings of your system components. Doing that can cause fire or electric shock by shorting out interior components. Position system cables and power supply cables carefully. Route system cables and the power supply cable and plug so that they cannot be stepped on or tripped over.
Be sure that nothing else rests on your system component cables or power cable. Do not modify power cables or plugs. Consult a licensed electrician or your power company for electrical modifications at your site. Always follow your local and national wiring rules. If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component damage.
Site Environmental Requirements Environmental monitoring in the router protects the system and components from damage caused by excessive voltage and temperature conditions. It allow you to mount on a front to rear rail variance distance of The following information can help you plan your equipment rack configuration: Allow clearance around the rack for maintenance.
Allow at least one rack unit of vertical space between routers. Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment at the bottom of the rack can be drawn upward into the intake ports of the equipment above it.
When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack. Ensure that the room where your router operates has adequate air circulation.
