Plug-in and Boot Up

1. Connect the AC adapter power connector to the 12VDC port on the ETH-4X1 Manual Ethernet Switch.
Make sure the power connector is properly inserted. (See Fig. 3.)
2. Plug the AC adapter into a power outlet. The "Power" LED on the ETH-4X1 Manual Ethernet Switch should
illuminate indicating that a proper power connection has been made.
