OL-11636-01
Never attempt to lift an object that might be too heavy for you to lift by
•
yourself.
Always disconnect the power source and unplug all power cables before
•
lifting, moving or working on the router.
Keep the work area clear and dust free during and after installation.
•
Keep tools and router components away from walk areas.
•
Do not wear loose clothing, jewelry (including rings and chains), or other
•
items that could get caught in the router.
Fasten your tie or scarf and sleeves.
•
The Cisco 12404 Internet router operates safely when it is used in accordance
•
with its electrical ratings and product usage instructions.
Do not work alone if potentially hazardous conditions exist.
•
Always unplug the power cables when performing maintenance or working
•
on the router, unless the replacement part is capable of online insertion and
removal, hot swappable.
The installation of your Cisco 12404 router should be in compliance with
•
national and local electrical codes: in the United States, National Fire
Protection Association (NFPA) 70, United States National Electrical Code; in
Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries,
International Electrotechnical Commission (IEC) 364, part 1 through part 7.
Before installing, configuring, or maintaining the router, review the safety
•
warnings listed in the document Regulatory Compliance and Safety
Information for the Cisco 12000 series Internet Routers (Document Number
78-4347-xx) that accompanied your Cisco 12404 router.
Cisco 12404 routers configured with the AC power entry module (PEM) are
•
shipped with a three-wire electrical grounding-type plug that will only fit into
a grounding-type power outlet. This is a safety feature. The equipment
grounding should be in accordance with local and national electrical codes.
Cisco 12404 routers configured with a DC PEM require a dedicated 35–Amp
•
DC circuit breaker for the DC power source. This circuit breaker should
protect against short-circuit and overcurrent faults in accordance with United
