How to configure the APC PDU, model number AP7930
You need to know the MAC address of the PDU and the IP address you want to give it. In this example the MAC address is 00:c0:b7:4d:a4:83 and the IP address is 10.10.10.2. This will assign 10.10.10.2 to the PDU. After doing this you can login with telnet using the username apc and password apc. You can also access the PDU with a web browser using http.
arp -s 10.10.10.2 00:c0:b7:4d:a4:83 ping 10.10.10.2 -s 113 telnet 10.10.10.2 # http://10.10.10.2/
This technique of remotely setting up a network device is known as ARP stuffing. It use used for relatively primitive device such as PDUs and security cameras.
