IO Conguration card
The IO Conguration card provides comprehensive print server status. The information provided is an important
diagnostic tool, especially if network communication is not available. For a description of messages that may
appear on the card, see the HP Jetdirect Print Servers Administrator’s Guide for your print server model.
For detailed connectivity information, go to the Connectivity menu and click Network card or Services card to see
all the information available.
The network card provides details about the network conguration and status. The services card provides
information about the state of connections to HP services, such as HP ePrint.
To verify correct operation:
1. On the network card, look for the status message I/O Card Ready.

b. Check that the status indicator lights (LEDs) are providing proper status.
