Installation Notes
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.

Operating 5-GHz Radio Requires Power Injector, Power Module, or Catalyst 3550-24 PWR Switch
The 1200 series power injector and the 1200 series power module support operation of the 5-GHz radio
in the access point. Currently, the Catalyst 3550-24 PWR switch supports power for both the 2.4-GHz
radio and the 5-GHz radio. Other switches and power patch panels might not provide enough power for
the 5-GHz radio.

Access Point Requires 1200 Series Universal Power Supply and Power Injector
If you use a power injector or a power module to provide power to a 1200 series access point, you must
use a 1200 series universal power supply. If you need to use a power injector to inject power into the
access point’s Ethernet port, you must use a 1200 series power injector.

Unpowered 1100 Series Access Points Cause Loopback When Connected to Switches Without
Loopback Detection
Loopback Detection
When you connect an unpowered 1100 series access point to a switch without loopback detection, the
access point causes a loopback. To avoid this problem, make sure loopback detection is enabled on the
switch to which the access point is connected. If your switch does not have loopback detection,
disconnect the access point from the switch when the access point power is off.
