•SG 시리즈 PoE 와 Cisco Aironet 1200 AP 연결 시 전원 공급이 안되는 현상이 있으며, 이는 PoE Device를 검출하는 방식과 연관되어 있습니다.
detection-type은 다음과 같은 방식이 있습니다.
2-point IEEE 802.3af 2-point Detection only
2-point-legacy IEEE 802.3af 2-point followed by legacy
4-point IEEE 802.3af 4-point Detection only (Default)
4-point-legacy IEEE 802.3af 4-point followed by legacy
legacy Legacy Capacitive Detection Only
none None
Cisco Aironet 1200 AP를 연동 시 SG 시리즈 PoE에서 poe detection-type 을 legacy 로 설정하면 정상적으로 동작합니다.
※ 전원 공급이 안 되었을 때 상태 Trouble shooting - PoE 에서 Cisco Aironet 1200 Series 연결 시 전원공급이 안되는 경우 poe detection-type 설정 변경
