S2626-PWR 端口故障

S2626-PWR 端口故障：POE不提供电或网络不工作。进入contrl 超级终端 显示如下错误：

System application is starting...RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 1651 *** [RT_ERR] dal/maple/dal_maple_port.c:936: In function 'dal_maple_port_phyAutoNegoEnable_get' Error Code: 0xFFFFFFFF *** [RT_ERR] dal/maple/dal_maple_port.c:1171: In function 'dal_maple_port_phyAutoNegoAbility_get' Error Code: 0xFFFFFFFF RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 1918 *** [RT_ERR] dal/maple/dal_maple_port.c:936: In function 'dal_maple_port_phyAutoNegoEnable_get' Error Code: 0xFFFFFFFF *** [RT_ERR] dal/maple/dal_maple_port.c:1250: In function 'dal_maple_port_phyAutoNegoAbility_set' Error Code: 0xFFFFFFFF RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 808 *** [RT_ERR] dal/maple/dal_maple_port.c:992: In function 'dal_maple_port_phyAutoNegoEnable_set' Error Code: 0xFFFFFFFF RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 904 *** [RT_ERR] dal/maple/dal_maple_port.c:936: In function 'dal_maple_port_phyAutoNegoEnable_get' Error Code: 0xFFFFFFFF *** [RT_ERR] dal/maple/dal_maple_port.c:1171: In function 'dal_maple_port_phyAutoNegoAbility_get' Error Code: 0xFFFFFFFF RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 1918 RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 347 RTK API error = -1, file hal/switch/realtek/rtk_drv_port.c, line = 1651

请问是软件问题或是端口物理坏了。

配置用工厂缺省配置。
