Installation Notes
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 48 VDC, and the access point is operational up
to 60 VDC. Voltage higher than 60 VDC can damage the equipment.
to 60 VDC. Voltage higher than 60 VDC 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.
