3. LAN 10/100 lights:
◆ If one light is on, a network connection is established at 10 Mbps or
100 Mbps. No problem indicated.
◆ If both lights are off, no network is detected. See “ Resolving
Communication Problems with the Network ,” below.
Resolving Communication Problems with the Network
Check the following items to verify that the projector server is communicating
with the network.
1. Are there any physical connection problems between the workstation or
file server and the HP Jetdirect projector server?
◆ Verify network cabling, connections, and router configurations.
◆ Verify that network cable lengths meet network specifications.
◆ Verify that network settings have been properly configured.
2. Are your network cables connected properly?
Make sure that the projector is attached to the network using the
appropriate HP Jetdirect projector server port and cable. Check each cable
connection to make sure it is secure and in the right place. If the problem
continues, try a different cable or network port on the hub or switch.
3. Is autonegotiation properly configured?
The speed and communication mode on the projector server must match
the network for proper operation.
The server’s RJ-45 network connector
has indicator lights to identify the
connection speed. Verify that either the
10 Mbps or 100 Mbps light is on.
4. Is the projector server connected to an
802.1X network and properly configured
for EAP/802.1X operation?
The network must support the Extensible Authentication Protocol (EAP)
method configured for use on the server.
Verify the configuration of the network’s 802.1X port. If it does not allow
guest or temporary access, you may need to preconfigure the Jetdirect
projector server for 802.1X operation before connection to your network.
This is done using an isolated LAN, or through a direct computer-to-Jetdirect
server connection using a cross-over cable.
