The optional USB device server is an interface board that adds an Ethernet port to the printer.
With this option installed, two Ethernet cables can be connected at the same time using the standard port on the printer and an additional port on the USB device server. You can assign different IP addresses to each port, so the printer can print jobs from different network segments.
Procedure for installing the USB device server

Turn the printer off and unplug the power cord.
Loosen the two screws and remove the slot cover.
The removed cover will not be reused.
Fully insert the interface board.
Check that the interface board is firmly connected to the controller board.
Tighten the two screws to secure the interface board.
Connect the USB device server to the printer.
