Resetting APC Switched Rack PDU’s
You need to be connected to them via the serial cable / console. Press the reset button and as soon as the status lights start flashing green/orange, press the reset button again, then press Enter on the keyboard until you get a prompt from the unit. The login username/password then is apc/apc.
Edit: the initial button press should be for 10 seconds or so.

APC PDU configuration trick
The MAC address is on the back of the PDU and on the Quality Assurance slip included in the package.
- Use ARP to define an IP address for the PDU, and use the PDU’s MAC address in the ARP command. For example, to define an IP address of 156.205.14.141 for the PDU that has a MAC address of 00 c0 b7 63 9f 67, use one of the following commands:
Windows command format:
arp -s 156.205.14.141 00-c0-b7-63-9f-67
LINUX command format:
arp -s 156.205.14.141 00:c0:b7:63:9f:67
- Use Ping with a size of 113 bytes to assign the
IP address defined by the ARP command. For
example:Windows command format:
ping 156.205.14.141 -l 113
LINUX command format:
ping 156.205.14.141 -s 113
- Use Telnet to access the PDU at its newly
assigned IP address.
For example:telnet 156.205.14.141
- Use apc for both user name and password.
At this point the IP address is configured for the interface, you can browse to the IP via HTTP. Don’t forget to delete your static ARP entry.
