Configuring System Power Settings for 1130 and 1240 Series 
Access Points
The 1130 and 1240 access points disable the radio interfaces when the unit senses that the power source 
to which it is connected does not provide enough power. Depending on your power source, you might 
need to enter the power source type in the access point configuration. Use the System Software: System 
Configuration page on the web-browser interface to select a power option. Figure 4-6 shows the System 
Power Settings section of the System Configuration page.

Using the AC Power Adapter
If you use the AC power adapter to provide power to the 1130 or 1240 access point, you do not need to 
adjust the access point configuration.
Using a Switch Capable of IEEE 802.3af Power Negotiation
If you use a switch to provide Power over Ethernet (PoE) to the 1130 or 1240 access point, and the switch 
supports the IEEE 802.3af power negotiation standard, select Power Negotiation on the System 
Software: System Configuration page. 
Using a Switch That Does Not Support IEEE 802.3af Power Negotiation
If you use a switch to provide Power over Ethernet (PoE) to the 1130 access point, and the switch does 
not support the IEEE 802.3af power negotiation standard, select Pre-Standard Compatibility on the 
System Software: System Configuration page.
