We have a bunch of 1130AG LWAPP access points that we are installing in various locations. Those locations with newer 802.3af switches such as the 3750's and 3560's power the AP's without issue. However we have mixed results plugging them in to older Cisco POE only 3524PWR Switches.
For the most part if we plug the 1130AG's into the 3524PWR's with short patch cords they power the radios up. However, if we connect them to a longer network line (80 to 100 feet) they disable the radios and WCS alarms tell me that the switch could not supply enough power for the radios.
The Quick Start Guide (page 14) shows the 1130AG supporting both Cisco POE and 802.3af power. Is there any way to get these to reliable power up on 3524PWR switches or do I need to use power cords or power injectors?
