The print server has a function to interlock the main power with the printer.
After enabling this function, the print server’s power turns OFF when the printer is turned off.
When the interlock switch is set to DS, the interlock function is OFF, and when the switch is set to EN, the interlock function is ON.
The power interlock switch is located at the rear side of the print server. It is recommended to use the print server with this switch set to EN.
