Configuring System Power Settings for 1040, 1130, 1140, 1240, 1250, and 1260 Series Access Points
The 1040, 1130, 1140, 1240, 1250, and 1260 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 4-7 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, 1140, 1240 or 1250 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 1040, 1130, 1140, 1240, 1250, and 1260
access point, and the switch supports the IEEE 802.3af power negotiation standard, select Power
Negotiation on the System Software: System Configuration page.
