SUGGESTIONS
Make sure your machine is powered on and is on-line and in Ready
mode. Print the Network Configuration list to see your current Network
settings. (See Printing reports on page 8-1.)
Reconnect the LAN cable to the hub to verify that the cabling and
network connections are good. If possible, try connecting the machine
to a different port on your hub using a different cable. If the connections
are good, the machine will show LAN Active for 2 seconds.
(If you are using a wireless connection or are having Network problems
see the Network User's Guide on the CD-ROM for more information.)
