Chapter 2 Installing the Access Point
Connecting the Ethernet and Power Cables
Connecting the Ethernet and Power Cables
The access point receives power through the Ethernet cable or an external power module. Figure 2-8
shows the power options for the access point.
Figure 2-8 Access Point Power Options ---- TBD ----
Warning
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
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
Note Some older switches and patch panels might not provide enough power to operate the access point. 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 and creates an error log entry (refer to the
“Checking the Access Point LEDs” section on page 6-2 and the “Low Power Condition” section on
page 6-6).
