If the print server failed to link, verify that all cables are correctly
connected. If all cables are correctly connected and the print server
still fails to link, follow the steps below to reconfigure the print server:
1
Turn off the printer and remove the HP JetDirect 10/100TX print
server.
2
Use jumpers P1, P2, and P3 to manually configure the print
server for either 10 or 100 Mbps (megabits per second) link
speed, and Full- or Half-duplex operation according to the table
below:
3
Reinstall the print server.
4
Verify that the configuration of the connecting network device
(such as a 10/100TX network switch) matches. For example, to
set the print server for 100TX Full-duplex operation, the port on
the network switch must also be set for 100TX Full-duplex
operation.
5
Turn the printer off and back on and check the print server
operation. If the print server fails to link, contact a local
HP-authorized dealer or service representative.
