Cisco Aironet 1131G - Radio access point AIR-LAP1131G-E-K9 User Manual

The access point can receive power from an external power module or from inline power using the 
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power 
Negotiation. Using inline power, you do not need to run a power cord to the access point because power 
is supplied over the Ethernet cable. 

This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source 
or an IEC60950 compliant limited power source. Statement 353

Be careful when handling the access point; the bottom plate might be hot.

The access point supports the following power sources:

Power module

Inline power:

Cisco Aironet Power Injector (AIR-PWRINJ3 or AIR-PWRINJ-FIB)

An inline power capable switch, such as the Cisco Catalyst 3550 PWR XL, 3560-48PS, 
3570-48PS, 4500 with 802.3AF PoE module, or the 6500 with 802.3AF PoE module

Other inline power switches supporting the IEEE 802.3af inline power standard

Some switches and patch panels might not provide enough power to operate the access point when 
configured with both 2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine 
that the power source can supply sufficient power, the access point automatically deactivates both radios 
to prevent an over-current condition. The access point also activates a Status LED low power error 
indication (refer to the 

 or 

the 

The access point has 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 NEC, and with Sections 2-128, 12-010(3) and 12-100 of the Canadian 
Electrical Code, Part 1, C22.1.

Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a 
building’s environmental air space; the AIR-PWRINJ3 power injector and the power module are not 
tested to UL 2043 and should not be placed in a building’s environmental air space, such as above 
suspended ceilings.
