10/100Base-TX Link Configuration
Introduction
HP J6057A (615N) or J4169A (610N) 10/100Base-TX print servers 
support 10 or 100 Mbps operation using full-duplex or half-duplex 
transmission channels. By default, the print server will attempt to 
autonegotiate its link operation.
When connecting to network hubs and switches that do not support 
autonegotiation, the print server will configure itself for 10-Mbps 
or 100-Mbps half-duplex operation. For example, when connected 
to a non-negotiating 10 Mbps hub, the print server card will 
automatically set itself to operate at 10-Mbps half-duplex.
If the card is not able to connect to the network through 
autonegotiation, you can manually set the link operating mode 
using one of the following methods:
● the printer’s control panel (if it has one). See Appendix A for more 
information.
● the embedded web server running on the Jetdirect print server.
● accessing the Telnet interface on the Jetdirect print server.
● using a TFTP (Trivial File Transfer Protocol) file downloaded, for 
example, from a BootP or DHCP server.
