Chapter 3 Installation Safety and Site Preparation
Power Guidelines and Requirements
Poletop Installation Requirements
The installation steps in this manual (Installing the Router) require that the router mounting and
installation locations, usually at the top of a power or other utility pole, have the following connections
available for basic router installation:
• AC power connection
• Fast Ethernet connection, as described in the section Ethernet Connections, page 3-5
Environmental Requirements
The location of your router is an important consideration for proper operation. Equipment placed too
close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns,
and can make maintenance difficult. Plan for access to both power supply side and cable side panels of
the router.
If you are currently experiencing shutdowns or an unusually high number of errors with your existing
equipment, these precautions and recommendations may help you isolate the cause of failure and prevent
future problems.
• Always follow ESD-prevention procedures described in the Preventing Electrostatic Discharge
Damage, page 3-2 to avoid damage to equipment. Damage from static discharge can cause
immediate or intermittent equipment failure.
• Ensure that the chassis door closes securely and that all empty module slots and have filler panels
installed.
• When other equipment is installed on or connected to the router, try operating the router by itself,
if possible. Power off other equipment (such as USB devices and installed third-party modules) to
allow the router under test a maximum of cooling air and clean power.
FCC Safety Compliance Statement
The FCC, with its action in ET Docket 9608, has adopted a safety standard for human exposure to RF
electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco antennas,
Cisco products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991.
Proper operation of this radio device according to the instructions in this publication results in user
exposure substantially below the FCC recommended limits.
Power Guidelines and Requirements
• Check the power at your site to ensure that you are receiving power that is free of spikes and noise.
• Install a power conditioner if necessary.
• Verify the AC power supply includes an autorange feature to autoselect 100 V to 240 V operation.
