The switch has Zero Touch Provisioning enabled. Zero Touch Provisioning (ZTP) enables switches "just out of the box" to automatically gain a management IP address and configuration without serial cables and manual configuration. The numbers seen on the display represent the IP address.
Link-Local addressing (subnet 169.254.x.x) allows a host device to automatically and predictably
derive a non-routable IP address for IP communication over Ethernet links.
The IPv4 address format is used to make it simple for a user to determine the switch's IP address. The
formula is to use the lower 2 bytes of the MAC address as the last two numbers in the Link-Local IPv4
* MAC address: 00:04:96:97:E9:EE
* Link-Local IP address: 169.254.233.238 or 0xa9fee9ee
