Finding the MAC address of the CCU2EN

A MAC address is a unique identifier assigned to network interface cards (NICs) during manufacturing. It's a 12-digit hexadecimal number that serves as a physical address for network devices within a local network. It is the "hardware fingerprint" of a device.

The MAC Address for a CCU2EN should be printed on a sticker next the the Ethernet port. However, if is not readily accessible or legible you can ping it directly using the windows Command Prompt. To determine the physical address of the unit, use the procedure below.

The instructions are for Windows 11 but would be similar for Windows 10.

  • Open Command prompt (Windows key, then type cmd):
  • Type: ping 192.168.1.223 (or the known IP of the CCU2EN)
    • This refreshes the cache, wait for it to finish
  • Type arp -a
    • This is the Address Resolution Protocol command and is for mapping IP addresses to the device MAC address (ARP) cache on a local network
  • Look at the Interface section for the CCU2EN's IP (you may need to scroll up)
    • The Physical Address next the IP is the MAC Address
