  1. Blue - Solid
    1. Normal Operation
  2. White - Flashing
    1. Unconfigured state
  1. No light/power
    1. Check power connection.
    2. Are you connected to a PoE enabled switch or PoE injector?
  2. Can only connect to the primary/default VLAN
    1. Check that your switch port has all VLANs enabled (Try cycling the port through 'Disabled')
  • What is PoE Passthrough
    • The US-8 switch can be powered via PoE in Port 1 (Labeled PoE In). Remaining wattage of the port is passed to Port 8 (Labeled PoE Out) to chain into a PoE powered device. FIXME Add simple diagram of this function for clarity?

Note: Without PoE input via port 1, port 8 will NOT have PoE.
