  Installation Notes
Use Only One Power Option
You cannot provide redundant power to 1100 and 1200 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. 
 shows the power configuration that can shut 
down the port on the patch panel or powered switch.

Improper Power Configuration Using Two Power Sources
Using the AC Power Adapter
If you use the AC power adapter to provide power to the 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 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 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. 
Using a Power Injector
If you use a power injector to provide power to the access point, select Power Injector on the System 
Software: System Configuration page, and enter the MAC address of the switch port to which the access 
point is connected.
