hi,
I have deployed a wireless network with a 5508 wireless lan controller with indoor and outdoor access points, the indoor ones are working fine but the 1552 outdoor ones are transmitting a very weak signal. when I check the advance features in the wlc. I see that the access point is operating in low power . when I try to add a poe injector, the APs wont rejoin the controller. I have attached a screenshot. What can I do to maximize the signal. Please help

1.To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=).
Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source.
2. The 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.
Note The PoE-out port is disabled when the access point is powered by the power injector.
Please refer to the below guide :

Power over Ethernet
When you power the access point over Ethernet, the access point does not supply 802.3af PoE to an Ethernet-attached device. When you use Power over Ethernet, use the power injector listed in Table 4.
Table 4. Power Injector for Use with Power over Ethernet
Product ID | Description |
AIR-PWRINJ1500-2= | 1520/1550 Series Power Injector |
Do not use any other power injector or switch for Power over Ethernet with the 1550 Series access points. The 1550 Series is approved for use only with the AIR-PWRINJ1500-2=. You must also specify the country type power cord for the power injector.
The AIR-PWRINJ1500-2= is for indoor use only. It has built-in surge protection, but you may also need to install a surge protector at the building entry point. Please check your local electrical regulations.
The 1550 Series access points use a standard RJ-45 Ethernet connector. Cisco does not provide an Ethernet cable for the 1550 Series. You will need to source an outdoor-rated, Category 5 or better Ethernet cable and shielded RJ-45 connectors from a local supplier. Liquid-tight adapters are provided with the access point to seal this cable entry point from weather.
