This section contains installation notes for access points.

Cisco Aironet 1130, 1240, and 1250 Series Access Points provide adequate fire resistance and low 
smoke-producing characteristics suitable for operation in a building's environmental air space, such as 
above suspended ceilings, in accordance with Section 300-22(C) of the National Electrical Code (NEC) 
and Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.

The power injector does not provide fire resistance and low smoke-producing characteristics and is not 
intended for use in extremely high or low temperatures or in environmental air spaces such as above 
suspended ceilings.

This section describes issues that you should consider before applying power to an access point.

Cisco Aironet power injectors are designed for use only with Cisco Aironet access points and bridges. 
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.

You cannot provide redundant power to 1130 series access points with both DC power to its power port 
and inline power from a patch panel or powered switch to the access point 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.
