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. Status LED "1" should also illuminate
indicating a connection between the "COMMON" port and user selectable port 1.
3. Power up the COMMON and SELECTABLE device(s). The COMMON device should react as if it were
directly connected to the SELECTABLE device plugged into user selectable port 1.
