Resolving communication problems with the network
To resolve communication problems with the network
Check the following items to verify that the all-in-one is communicating with the network. This
information assumes you have already printed a Network configuration page (see
).
1.
Are there any physical connection problems between the workstation or file server and the all-in-
one?
Verify that the network cabling, connections, and router configurations are correct. Verify that
the network cable lengths meet network specifications.
2.
Are your network cables connected properly?
Make sure that the all-in-one is attached to the network using the appropriate 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 ports on the hub or transceiver. The amber activity light and
the green link status light next to the port connection on the back of the all-in-one should be lit.
3.
Are the link speed and duplex settings set correctly?
Hewlett-Packard recommends leaving this setting in automatic mode (the default setting). See
Link speed and duplex settings
.
4.
