我最近有几张二手 APC 网络管理卡 (一个 AP9617 和 AP9630). 两者都设置了静态 IP (即. 他们没有从 DHCP 获得地址) 所以为了访问他们的网络界面，我需要找到他们.
With the AP9630 one option is just to reset it (press a paperclip or similar into the reset hole and hold for 20+ 秒) but this doesn’t work for all cards (e.g. it didn’t work for the AP9617)
The easiest way to connect the card up to my network with an ethernet cable, then install Wireshark. Double click on your main network connection to monitor the traffic on it and then in the “apply a display filter” field at the top enter the following
You might then have to wait 2–3 minutes. Or alternatively try unplugging and replugging the network cable from the management card. You should see a “who has x.x.x.x” entry appear fairly soon. The source of the request (which will likely be x.x.x.y) 是 知识产权 of the card. To connect to it you just set a manual 知识产权 for your own network card on the same range with a different ending — x.x.x.z
This works because the first part of the MAC address of all APC cards is 00:c0:B7 and you’re unlikely to have any others on your network. If you do have others on your network then just use a network cable directly connected between your NIC and the network management card and do the same process.
