HP 4050 manual Print Server Operation Jumper P1 Jumper P2 Jumper P3

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:

1Turn off the printer and remove the HP JetDirect 10/100TX print server.

2Use 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:

Print Server Operation			Jumper P1	Jumper P2	Jumper P3
Autonegotiation Enabled			AUTO	—	—
100		Half-duplex	(not AUTO)	100	H
100		Full-duplex	(not AUTO)	100	(not H)
10	Half-duplex		(not AUTO)	(not 100)	H
10	Full-duplex		(not AUTO)	(not 100)	(not H)

3Reinstall the print server.

4Verify 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.

5Turn 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.
