Installing the DP-300
WARNING:
Configuration problems may result if the DP-
300 is powered up without first establishing its
network connection. Follow this procedure to
avoid complications at the configuration stage.
1.
Confirm proper operation of each of the printers to be connected to
the DP-300. If you test your printers by printing test files directly
from a PC, then make each printer’s test connection to the PC
through the same port (serial or parallel) as the one you plan to use in
connecting to the DP-300.
2.
When you have confirmed proper operation of each printer, switch
its power off.
3.
Confirm that your network is operating normally.
4.
Connect the DP-300 to the network, using the RJ-45 (10Base-
T/100Base-TX) connector on the print server’s side panel.
5.
While each printer is powered off, connect its tested and confirmed
port to a like printer port of the DP-300. If you are connecting fewer
than three printers, then keep in mind that parallel- port connections
are preferred for high-performance printers.
6.
Switch on each connected printer.
7.
Plug the DC power adapter’s DC output plug into the DC 12V power
socket on the side panel of the DP-300.
8.
Plug the power adapter into an electric service outlet. This will
supply power to the DP-300, as it has no external power switch. The
Power/Tx LED on the DP-300’s front panel should light steady
green, and the DP-300’s self-test will proceed.
