Setting up the DP-300U
Installing the Print Server
WARNING: Configuration problems may result if the Print Server is powered up
without first establishing its network connection.
Follow this procedure to avoid complications at the configuration stage.
1. Confirm proper operation of the printers to be connected to the DP-300U.

of the Print Server
6. Switch on the connected printer.
7. Plug the AC power adapter’s DC output plug into the DC 5V power socket on the

8. Plug the power adapter into a power outlet. This will supply power to the Print
Server, as it has no external power switch. The green Power LED on the Print
Server’s front panel should illuminate steadily, and the Print Server’s Self-Test
will proceed.
