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://<ip-address>
  • 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.

  1. Determine the reader's self-assigned IP address by pinging the hostname:
    • Windows (PowerShell):
      • ping -4 xspan-XX-XX-XX.local
      • You should see something like this: Pinging xSpan-13-69-B9.local [169.254.1.1] 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.
  2. Set your computer's IP address and subnet mask manually:
    • IP Address: 169.254.1.10
    • Subnet mask: 255.255.0.0
  3. Connect to the reader's web interface with the IP address to confirm connectivity:
    • http://<ip address>
  4. After verifying that the web interface is accessible, log in via ssh and enable DHCP using RShell:
    • ssh root@<ip address>
    • 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.
    • > reboot
      • This will reboot the reader. After reboot, DHCP will be enabled and the reader should get an IP address assigned automatically.
  5. Set your computer's IP address and subnet mask back to their original values.
