Installation Notes
Note
If you plan to mount the access point in an area subject to environmental air space with the intention
of upgrading to a 5-GHz radio, Cisco recommends that you mount the access point horizontally so
that its antennas point down. Doing so ensures that the access point complies with regulatory
requirements for environmental air space after the 5-GHz radio is installed.

Caution
The Cisco Aironet Power Injector has a smaller operating temperature range (32 to 104
o
F; 0 to 40
o
C)
than the 1200 series access point. The power injector is not intended for use in extremely high or low
temperatures or in environmental air spaces, such as above suspended ceilings.

Antenna Installation
For instructions on the proper installation and grounding of external antennas, refer to the National Fire
Protection Association’s NFPA 70, National Electrical Code, Article 810, and the Canadian Standards
Association’s Canadian Electrical Code, Section 54.

Warning
Do not install the antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, as they may cause serious injury or death.

Power Considerations
This section describes issues you should consider before applying power to the access point.
Caution
The nominal voltage for 1200 series access points is 48VDC, and the access point is operational up
to 60VDC. Voltage higher than 60VDC can damage the equipment.

Caution
Cisco Aironet Power Injectors are designed for use with 1200 series access points only. Do not use
the power injector with any other Ethernet-ready device. Using the power injector with other
Ethernet-ready devices can damage the equipment.

Ethernet-ready devices can damage the equipment.
Use Only One Power Option
You cannot provide redundant power to the access point with both DC power to its power port and inline
power from a patch panel or powered switch to the access point’s Ethernet port. If you apply power to
the access point from both sources, the switch or power patch panel might shut down the port to which
the access point is connected.
