Cisco Aironet 1250 Series Manual page 22

The access point power options:
•
Option 1—Switches with sufficient inline power (single radio only):
– An inline power capable switch, such as the Cisco Catalyst 3550
PWR XL, 3560-48PS, 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
•
Option 2—Switches without sufficient inline power can use the power
injector (two radio operation):
– – 1250 series power injector (AIR-PWRINJ4)
•
Option 3—Local power using the 1250 series DC power module
(AIR-PWRSPLY1)
•
Option 4—An 802.at compliant PoE switch
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 Status LED
turns amber and an error log entry is created
