Impinj xSpan - Troubleshooting Connection The xSpan reader should by default have DHCP enabled, allowing you to connect via: http://xspan-XX-XX-XX.local (where the X values are the last 3 bytes of the MAC address) http:// username: root password: impinj However, if you're unable to connect, DHCP may be disabled, in which case you need to connect to the device on its local link address (most likely 169.254.1.1 ) and use RShell to enable DHCP. Determine the reader's self-assigned IP address by pinging the hostname: Windows (PowerShell): ping xSpan-XX-XX-XX.local You should see something like this: Pinging xSpan-13-68-53.local [fe80::216:25ff:fe13:6853]%11 with 32 bytes of data: The address in [brackets] is the address of the reader. macOS (Terminal): ping -c 1 xspan-XX-XX-XX.local You should see something like this: PING xspan-13-69-b9.local (169.254.1.1): 56 data bytes The address in (parentheses) is the address of the reader. Log in via ssh and enable DHCP using RShell: ssh root@ password: impinj > show network summary You'll likely see ipAddressMode='Static' . This confirms that DHCP is disabled. > config network ip dynamic This will enable DHCP and reboot automatically. After completing these steps, you should be able to access the reader on your LAN.
