ThinNet Interface: Change Jumper First
You need to change a jumper inside the Ethernet Print Server unit before
you can print using the ThinNet Ethernet interface.
How to Change the Ethernet Print Server Jumper
The Ethernet Print Server is designed to withstand minor bumps and bangs
without accidentally opening. Follow the steps in this section to open the
plastic unit if you need to change the jumpers from the Ethernet 10BASE-T
interface to the ThinNet interface. The default is the 10BASE-T interface.
1. Make sure you do not have the Ethernet Print Server unit plugged into a
wall outlet. If it is, unplug the power cord before you open the unit.
2. Hold the side of the unit against your body. Grab the side that is the
farthest away from your body and press the bottom half of the unit inward
toward you. Pull the two halves apart, as shown in Fig. 3-2.
