Chapter 2 Preparing for Installation
Site Requirement Guidelines
Power Connection Guidelines
Follow these precautions and recommendations when planning power connections to a Cisco uBR7100
series router:
• Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
• The AC power supply includes the following features:
–
Autoselects either 110V or 220V operation.
–
All units include a 6-foot (1.8-meter) electrical power cord that is appropriate for the country
of operation.
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
the protective device is rated not greater than: 15A minimum, 60VDC.
Statement 1005
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Statement 1024
• Use a grounded AC power outlet and install proper grounding to avoid damage from lightning and
power surges.
• The AC-input power supply operates on input voltage and frequency within the ranges of 100 to
240 VRMS and 50/60 Hz without the need for operator adjustments. This power supply also
incorporates an active power factor corrector that minimizes the unwanted generation of line current
harmonics that can cause overload of site electrical distribution systems.
Note We recommend an uninterruptible power source to protect against power failures at your
site. We recommend powering a Cisco uBR7100 series router from a 15A receptacle at the
power source.
