Preparing for Installation 2-3
Safety Recommendations
Review the safety warnings contained in the document entitled Regulatory Compliance
and Safety Information for the Cisco 12000 Series Gigabit Switch Routers (Document
Number 78-4347-02). This document accompanied the shipment of your Cisco 12008
router; familiarize yourself with its contents before attempting to install, configure, or
maintain the router.
Cisco 12008 routers configured with AC-input power suppli es are shipped with a 3-wire
electrical grounding-type plug that fits only into a grounding-type po w er outl et. Th is is
a safety feature that you should not circumvent. Equipment grounding should comply
with local and national electrical codes.
Cisco 12008 routers configured with DC-input power supplies require a 40-ampere DC
circuit breaker for the input DC power source. This circuit breaker should protect
against short-circuit and overcurrent faults in accordance with United States National
Electrical Code NFPA 70 (United States), Canadian Electrical Code, part I, CSA C22.1
(Canada), and IEC 364 (other countries).
Only a DC power source that complies with the safety extra-low voltage (SELV)
requirements in UL950, CSA 950, EN 60950, and IEC950 can be connected to a
Cisco12008 DC-input power supply.
A Cisco 12008 configured with DC-input power supplies that is to be used in a restricted
access area must be installed in accordance with Articles 110-16, 110-17, and 110-18
of the National Electric Code, ANSI/NFPA 70.
A Cisco12008 configured with DC-input power supplies must have a readily accessible
disconnect device incorporated in the fixed wiring for the site.

having to move the router later to accommodate the availability/proximity of power sources
and network interface connections.
Whenever you lift or move the router (or any other heavy object), observe the following
guidelines:
