Q.
Is the Cisco Aironet 1240AG Series UL2043 plenum rated?
A.
Yes. UL2043 is a standard specified by the Underwriters Laboratories. In the United States, most municipal
building codes require certain UL certifications for equipment used in buildings. Municipalities often specify
UL2043 certification for equipment used in the plenum air spaces. Municipalities also define what they
considered to be plenum air space. In some U.S. municipalities, the plenum air space only includes the area
above a suspended ceiling. In others, the area below the suspended ceiling may also be considered the plenum
area.
Q.
What are the powering options for the Cisco Aironet 1240AG Series? Is the Cisco Aironet 1240AG Series
802.3af-compliant?
A.
The Cisco Aironet 1240AG Series supports local power or inline power; supported inline power sources include
802.3af-compliant power sources, newer Cisco inline power-capable switches supporting 13W or greater, and
Cisco Aironet power injectors.
Q.
If I have Cisco inline power sourcing equipment that is only able to deliver 6.3W to powered devices, can
I reduce the power requirement of the access point to below this level by turning off one of the radios?
A.
No, Cisco Aironet 1240AG Series access points require about 12.94W, regardless of whether it is configured to
operate a single 802.11a or single 802.11g radio, or both. If inline power is required for Cisco Aironet 1240AG
Series operation, use an 802.3af-compliant power source, Cisco Aironet Power Injector, or higher-power Cisco
switches capable of supporting 13W or greater, such as the Cisco Catalyst
®
3750 Series, to provide adequate
power to the access point.
